Thursday required an early start to beat the infamous N1-traffic and have breakfast at the Rcafe in Long Street (go here to find out more) before starting our day. We left Brackenfell at 05:17, which was actually later than our original ITD of 05:00. ITD? My shorthand for Intended Time of Departure. We were parked in front of Rcafe by 05:45 which meant that the trip had taken us a mere 28 minutes. As soon as the doors opened at 06:00 Lynnette and I went inside to order two much needed Americano’s to start the day properly. What really amazed us was that the owner and staff recognized us the moment we walked in the door and it was a few days more than a year since we’d last been there! Auke arrived shortly after us and ordered his cappuccino. After breakfast, we headed for the Iziko South African Museum (click here for more information) where Benjamin was waiting to unlock the gates for us and set out the traffic cones to prevent vehicles entering our display and observing space in the amphitheatre. The weather was clear but blustery. The wind was, in fact, such a nuisance that I eventually took down and put away the posters, as the frames were being badly scratched every time they toppled over onto the brick paving. Anyway, by 08:00 we were ready to roll and all we needed was a visitor or two, which we soon got.
Thursday’s are popular school days at Iziko and we had three groups that we managed to convince that they should take a peek at the Sun. There were several other school groups whose teachers waved us away when we invited them to view the Sun. Being a weekday many of our visitors were from outside the country’s borders as most South Africans were hard at work earning an income. Many of the tour guides with the groups declined to let their tourists take a look at the Sun. Their reason was mostly that they had a schedule to keep to and did not have the time. Nevertheless, we had groups from Gabon, Thailand, Hong Kong, France, Netherlands, Israel, and Germany.
It was also nice to have the research staff from the backrooms of Iziko pay us a visit. I was especially pleased to make the acquaintance of Jay van den Berg a palaeontologist on Dr Roger Smith’s staff and Clair Browning the newly appointed Curator of the Karoo Collection.
The problem of getting people to sign our visitor’s book was highlighted for the umpteenth time. Many people who viewed the Sun through our telescopes flatly refused to sign the list and some actually became quite agitated when asked to do so. This problem is exasperated when one is busy and you simply do not have time to chase after people and ask them to sign. So, once again, our signature total (288) and counter tally (597) do not agree. I am more convinced than ever that the answer lies in devising a means to automatically count the number of people who look into each telescope’s eyepiece.
Because the Sun appears as a very bland and uninteresting white ball as a result of of the solar filter fitted to Lorenzo, many viewers say it looks like the Moon. So I decided to do some experimenting with filters to make the image more “exciting”. The images were all taken with my mobile and I am afraid that I do not have the world’s steadiest hand, so the photos are not of the best quality.
Sunday was an almost perfect day for an outreach event in the amphitheater of the Iziko South African Museum (click here for more information) in Cape Town. Lynnette and I, unfortunately, got there a bit later than we had intended. Auke had almost finished setting up by the time we arrived and we just managed to get Lorenzo setup before the first visitors put in an appearance.
While we were setting up, Benjamin, the museum security guard, came round to say hello and put out the traffic cones thereby preventing people from attempting to park among the telescopes. Throughout the rest of the day, he appeared every now and again, keeping a watchful eye on the ever present idlers and strollers who often have less than honest intentions.
We had a steady stream of visitors throughout the day. However, every time a tour group passed through the activity around the telescopes peaked and required all hands on deck. It was really a pity that, other than one lone sunspot (2670) which was about to disappear over the rim of the sun, there was no activity to be seen. I found the overseas visitors far more aware of astronomical matters than the South Africans. Having said that though, Lynnette had one local three-year old who knew the names of all the planets and, when quizzed, also knew which planet was the smallest and which was the largest!
All in all, it was a very pleasant day with the wind dying down by mid-morning and the few clouds that there were never really posing a serious threat to our solar observing. One of the problems, that occurs every year, with this kind of event is the effort to get people to sign our visitor’s register. Some people just refuse point blank and others again refuse to give contact details. During periods of high activity, when everyone is manning a telescope, we also lose signatures because there is nobody available to monitor if visitors sign the register or not. Our counters, as is usual, gave far higher figures than the number of signatures but, because one is busy with visitors, one probably also misses visitors with the counters. Maybe we should get some inventive person to install a counter at the eyepiece that counts when people look into it.
This was an event with a difference. Jeanne’s daughter, Jade, had her birthday the previous day and this was a camp-out party on their very nice property in the shadow of Table Mountain near Kirstenbosch. We found the address easily and our summary of the property from Google Earth was quite accurate except that the oak trees on the eastern side were higher than we had estimated which made viewing Jupiter a problem.
Patience let us in and helped us to decide on where to park the car. I then carried Lorenzo and all the other gear to the area we had chosen to set up and got everything organised. We had promised to bring each partygoer a light pollution booklet, an eclipse viewer and a set of solar system stickers. Auke was going to bring the personalise Southern Star Wheels and also show the girls how to assemble and use them as well as do the what’s up. I had just finished setting up when Auke phoned to say that he was about six minutes away (right on schedule) when he discovered he had left the Star Wheels at home. At that point, he was already heading back to Somerset West to fetch them and would we please adapt the program and carry on without him.
Auke had also phoned Jeanne to inform her of the hiccup so we decided to get the girls to look at the moon, which was clearly visible while it got dark enough, to actually do a what’s up. At this point, we noticed the wisps of cloud coming over the mountain and slowly spreading away from it towards us. Using the time honoured ostrich tactics of sticking your head in the telescope and pretending you don’t see the clouds, we lined the girls up and did several rounds of moon viewing. When the moon lost its allure the girls went back to the tents and collected blankets and other warm stuff before gathering around the fire.
Lynnette had already given the handouts to Jeanne but I took a little time to explain the use of the eclipse viewer stressing all the usual things about never looking at the sun with the unprotected eyes. I also stressed the fact that one should never look at the sun through binoculars or telescopes or through a camera unless the equipment was equipped with a proper solar filter.
I then gave a short talk and a brief what’s up but by that time the clouds had already covered part of Orion and Lepus and were making their way slowly toward Canis Major. Crux was still open as was most of the southern sky and the moon. Jupiter was still stuck behind the oaks when Auke pitched and did his thing with the Southern Star Wheel and it was still there by the time he had finished his little show.
Jeanne indicated that the girls now had other activities to attend to so there would be no waiting for Jupiter. Having done what we came to do we packed up and left, shepherded out again by a very friendly Patience.
I do not know which of the following is applicable to our case “You cannot have your cake and eat it” or “What you gain on the swings you loose on the roundabouts”. On the one hand we had bright sunshine and a six day old waxing moon that was situated very nicely but, on the other hand, we had a brisk and fairly chilly South-Easter that pushed clumps of fluffy clouds across our field of view all afternoon and, to top it all, there were only two minuscule sunspots visible.
Auke was already there and Eddy and Jannie arrived shortly after us with Dirk about 30 minutes after them. Alan and Rose weren’t there because Alan had to work and Wendy could also not make it as her husband was ill and had been hospitalized.
The brisk South-Easter was quite cold and, as we had suspected the wind drove a never ending series of fluffy clouds across the face of the Moon limiting viewing to the intervening gaps between them. I decided not to even try the Sun as the two diminutive sunspots were really not worth the effort and concentrated on the Moon.
There were fewer people around and this seems to be the pattern when there is a bit of wind. I also think that in the wind people tend to bunch up more at the Swing Bridge and are less inclined to look around. There seems to be a greater sense of urgency to get across. Also for the people coming from the other side they seem to move straight on and not fan out as they do on days when there is less wind.
There were fewer clouds as the afternoon wore on and by sunset we had almost uninterrupted views of the moon. I decided to give viewers a special treat and added a 3x Barlow to my 25 mm eyepiece. That never fails to draw Wows, OMG’s, Awesome’s. Nooo’s and even a You Lie or two from the viewers. It takes a bit more nudging and shoving, but the effect on viewers is more than worth the trouble. In addition Lorenzo has the advantage of being more stable and less prone to wind induced vibrations than the smaller telescopes.
Once the Sun was down it became really chilly and one once again had to marvel at the fact that one could actually show people celestial objects from such a heavily light polluted site as the Pierhead. Unfortunately Venus and Saturn were not well placed for viewing from our position and the best position would have been under the coloured fairy lights on the quayside.
We had bright sunshine and clear skies but on the way into Cape Town there was a suspicious looking cloud hanging around over the Eastern end of Table Mountain and the Devil’s Peak. I say suspicious because clouds like that, more often than not, are the forerunners of a South-Easter in Cape Town. This proved to be correct in this case although it did not develop into a full scale gale it was cold and a nuisance on the Pierhead.
By the time the Noon Day Gun (there is an informative piece on Wikipedia about this Cape Town icon) had sounded we were on site and setting up, followed shortly by Alan and Rose and then by Dirk. Auke and Wendy arrived a bit later. Wendy was just back from gallivanting around England and had brought het new telescope along for its inaugural session. The wind very quickly gave us to understand that today was not a day for banners, or A-frame poster displays. Later on it even toppled our trestles with the A2-framed posters and some of the gusts turned over tables and caused general mayhem. Dirk and Wendy’s smaller telescopes constantly had the jitters and even Alan’s eight inch Dobby and Lorenzo were not completely steady.
The moon was well up by 13:30 so Dirk could get his scope set on that as he does not have a solar filter for viewing the Sun. The Sun, by the way, was sporting a nice crop of sunspots unlike on our previous outing. I don’t know if it was the wind but the people were disinclined to look through the telescopes and needed quite a bit of coaxing. We eventually tallied up just under 600 visitors but felt that, with the sunshine, we should have had more.
The Chairperson of ASSA’s (Astronomical Society of Southern Africa) Cape Centre, Eddy Nijeboer also paid us a visit. Thanks Eddy it was nice to have somebody from the Cape Centre joining Wendy at the Pierhead. You can go here to find out more about ASSA and visit this page to find out more about the Cape Centre. If you are interested in astronomy please join ASSA or, if you live in Cape Town join the Cape Centre.
Venus was a nice early evening target for a short while and Saturn was well positioned for viewing. The Moon is always a good attraction and never fails to elicit exclamations of surprise, delight or amazement from even the apparently disinterested viewers. Despite what looked like clear skies, it soon became apparent the wind was driving moisture through the atmosphere somewhere above us, because the view through the telescope was just not as crisp as we would have wanted it to be. This wasn’t as visible when looking at the Moon but the effects were quite pronounced when looking at Saturn.
After the show we all had coffee at Den Anker served by our favourite waitron, Patrick, before heading home. Go here to find out more about this Belgian restaurant in the Waterfront.
August in the Western Cape is known for wet, blustery and cold conditions so we were mentally prepared for the worst during National Science Week 2016. However, the weather was uncharacteristically fine except for the last two days. Fortunately for us the Iziko South African Museum (go here to find out more about this exciting venue) allowed us to move inside and use the large open area adjacent to the now non-existent cafe. Thank you Elsabé and Theo for all your efforts on our behalf.
National Science Week had to be move forward by one week due to the local elections. That also caused some problems because we had already started making arrangements and the change meant changing other things as well. The run-up to National Science Week was a also unsettling because our sponsors had organizational problems, which meant that both the funding and the display material were very, very late. Late funding meant that we had to postpone all purchases and rentals until the very last minute which resulted in a lot of frantic rushing around with panic levels going off the scale every now and again. Scary stuff but we made it in one piece although it was really touch and go with some plans having to be partially shelved due to a lack of time to implement them properly.
Our setup this year shared the amphitheater with the impressive DNA model of the Past All from One Exhibition. Please go here to read more about this interesting exhibition sponsored by Standard Bank.
We had many visitors from overseas and also many visitors from other African countries. Despite the rather nerve racking preparation phase everything actually went off quite well. We definitely had more dubious characters hanging around this year than in 2014. Special thanks to the Iziko security staff who were very efficient and here Benjamin stands out and, quite honestly deserves a medal for his efforts. Despite their surveillance we had items “disappear”, among others Lynnette’s phone and that loss is still having repercussions almost a month later.
But, by and large it was a successful week with lots of sunshine making it easy to demonstrate and discuss renewable energy. The solar cooker, solar oven, and various solar power driven devices were all put to good use and other equipment was used to demonstrate the existence of energy at other wavelengths in the solar spectrum. We also used the telescopes equipped with special filters to good effect so that people could take a look at the sun, the source of all this free energy.
Our poster about solar energy depicted the photo-voltaic plant about 6 km outside the town of De Aar in the Northern Cape Province (go here to read more about this development). The other three projects we mentioned and discussed were Concentrating Solar Plants also situated in the Northern Cape Province. !Ka Xu is located about 40 km from the town of Pofadder (go here to read more about this innovative development). Close-by and just off the R358 Onseepkans road lies a similar development Xina (read more about this by going here).. Equally interesting is the !Khi Solar one project which is being constructed close to the town of Upington (go here to read more about this development).
Many of the South African visitors were totally oblivious of the efforts currently underway in South Africa to harness wind and solar energy. It is indeed a great pity that the handout material was so totally unrelated to the topic of Renewable Energy because people looked for something tangible to take away with them after visiting us and were noticeably disappointed when they discovered that the handouts were not related to the topic.
The late arrival of the handouts and posters also meant that we had to improvise in order to organize our usual displays at the three largest public in our area. Fortunately some of the librarians were very resourceful and able to contribute very good ideas.
It is also a pity that we did not get to see a member of the official inspectorate as we felt that we had a very good setup. As luck would have it an official photographer did turn up on one of the days when rain had forced us indoors. Our indoor display was not nearly as impressive as the outdoor one and, of course, the photographer turned up when we had a very quiet period and only a trickle of visitors.
Our total number of visitors was well over the 4 000 and at the three Libraries we supplied material to, we reached another 12 000 to 15 000. The circulation figure of the newspapers we advertised in was over one and a half million, so the exposure for National Science Week this year, was quite substantial. The NRF/SAASTA should be well satisfied with the number of people reached for the money they spent.
We can only hope that we have very good weather again next year and a smoother, less stressful run-up to the event.
We had bright sunshine and clear skies which was nice but there were no sunspots and also no moon before almost 21:00. So why on earth did we choose Saturday the 20th to set up in the waterfront? Actually we didn’t exactly choose it, it was chosen for us by circumstances. Our scheduled date was Saturday the 13th of August but, let me go right back to the beginning and explain what happened.
We had to decide whether to cancel our Waterfront date on the 13th or to move it one week on. We opted for the latter choice, knowing that the moon would only be out later but still hoping for some sunspots. We didn’t have sunspots, but the change of date wasn’t all negative because the weather was overcast and rainy on the 13th so we would not have been able to set up in the Waterfront in any case.
So, there we were with no sunspots and a late moon but beautiful weather and lots of enthusiastic people (680 visited us) all eager to get to know more about astronomy. Auke also had a table set up with some of the material and demonstrations on renewable energy that we had used during National Science Week. This also attracted quite a lot of attention.
The lack of sunspots gave us the opportunity to talk about other aspects of astronomy and space exploration, after allowing people to view the sun through our specially protected telescopes. Our display about space junk attracted a lot of attention as well. The fact that outer space was a mere 100 km away compared to all the other places on the Pierhead signpost left many of our visitors a bit shell shocked too.
Dirk was not quite his normal chirpy self and still had a cough and sore ribs after his recent indisposition, so he left pretty sharply at 21:00 to get out of the cold night air. Alan and Rose also opted to get home and get some well earned rest while Auke, Lynnette and I decided to have coffee at Den Anker (click here to find out more about this delightful restaurant), where Patrick was delighted to see Lynnette and I again.
Also on the positive side I should mention that we had very little dew, so our equipment and other material was put away dry. This meant Lynnette and I could pack everything away without first unpacking all the stuff and laying it out in the sun to dry. What a joy and also a huge saving in time and effort for the two of us.
“Third time lucky” is an expression one often hears and it certainly applied to or stargazing efforts at the Pierhead in the V&A Waterfront. After poor weather in May and worse weather in June we had fantastic open skies this time. Unfortunately the Sun wasn’t as well endowed with sunspots as we would have like it to be, which immediately brings to mind the hackneyed expression “What you lose on the swings, you gain on the roundabouts”.
Lynnette and I made had to first drop John-Henry off in Mowbray but we were still first on the scene followed by Alan and Rose, then Dirk and lastly Auke and the birthday girl, Wendy. It soon became clear that the fine weather had lured the visitors out in force and there were many more people in the Waterfront than on either of our previous visits. We were soon very busy.
Alan and Rosemary had their eight-inch Dobsonian set up close to the water’s edge. I suppose you can take a man out of the Navy but you can’t really take the sea out of a naval man, Alan? Dirk set up his Celestron close to the two red poodles, probably because he missed his Yorkies, while Auke and Wendy set up Maphefu, Auke’s eight-inch Dobsonian, an outreach veteran, next to the signpost.
Auke had his very nifty demonstration of how to use a simple pinhole to calculate the size of the Sun set up there as well. Lynnette and I set up Lorenzo our workhorse 10-inch Dobsonian, also a veteran of many outreach events, a short distance away from Auke and Wendy.
I was surprised by the large number of foreigners but should not really have been, because the V&A is known to be a magnet for foreign tourists. One Spanish family, on seeing the name Lorenzo on our telescope, came up with the following interesting piece of information.
It was a warm sunny day with very few sunspots but lots of interested and interesting people. The 30% illuminated waxing moon had risen shortly after 11:00, so it was well positioned for Alan and Dirk who do not have solar filters for their telescopes. My, soon to be patented, (Bob) Marley 40 mm Solar-finder worked very well and the erudite Mr Cassells even complimented me by saying it looked “very professional”.
Once the Sun went down it quickly became chilly but the sky was clear and we were able to show the Moon in high definition as well as Jupiter, Mars and Saturn to a host of visitors. I used a 9 mm eyepiece on Lorenzo, which gave visitors a quite spectacular view of the Moon and the other objects but also meant that I was kept busy making corrections to keep the objects in the field of vision.
We packed up at 21:00 just as the dew was beginning to become problematic. At that stage there were still quite a few people around but with a tally of 1622 visitors on our counters we felt that enough was enough. After packing up we handed over Wendy’s birthday present and went our various ways homeward.
On outings like this one always encounters people with odd requests and non-mainstream views and Saturday was no exception. There was one small group that insisted I show them the planet Nibiru and all my diplomatic attempts to convince them of its non-existence came to naught. I eventually resorted to verbal force majeure to get rid of them when they became abusive about my inability to show it to them. This by the way was all in broad daylight! Another gentleman insisted that the telescope was an instrument of the anti-Christ and that Saturn was, in fact, Satan’s seat of power. He eventually wandered of proclaiming to all and sundry that science was actually the anti-Christ not just poor Lorenzo. Lorenzo was relieved.
On Sunday it was all about unpacking and putting all the stuff out to dry before packing everything away again.
When Lynnette and I left Brackenfell the conditions were not all that good for viewing the Sun and we hoped that they would improve during the course of the afternoon and evening. The clouds were thin and patchy so there was some hope.
We had hardly stopped at the Pierhead in the Waterfront when Alan and Rose arrived followed very shortly by Auke and Wendy. Dirk had been delayed and only arrived quite a bit after the rest of us. We set up quickly and got Lorenzo and Maphefu onto the Sun. The high level clouds blurred the image and made it difficult to see the two large sunspots but when the Sun got into a fairly clear patch the image was good. The conditions were not all that pleasant and the cold wind probably reduced the numbers of visitors to the Waterfront because there were definitely fewer passersby than on our previous visit.
While Wendy and I kept the visitors busy on Lorenzo and Maphefu, Dirk was setting up and Auke and Alan were measuring out the size of the Sun in comparison to the inflatable Earth globes we had brought along. They also used chalk to draw the relative sizes of the planets around the signpost on the Pierhead.
Lynnette had packed some delicious sandwiches for the two of us, which went down really well. She had also bought a variety of very nice muffins which she shared out to the rest of the crew to have with their coffee. Lynnette also did her usual with the visitors lists when the telescope operators were tied up and operated Lorenzo when I had to do something else. Her skill at finding the Sun with the Dobsonians also came in very handy when Auke, Wendy or I struggled to find it.
The gusty conditions blew the cover off Lorenzo and sent it spinning over the edge of the pier. Fortunately it lodged in a position where Alan could retrieve it. We had two disasters with our inflatable Earth globes. In one case a boy decided to practice his soccer kick on one and broke the tag to which the string for holding it is attached. To the boy’s mother I would like to say that grabbing his hand and hustling him away as if nothing had happened, sets a very bad example to him and shows a regrettable lack of responsibility on your behalf. The same comment applies to the three youths who forcibly dislodged the other Earth globe and then had the temerity to chirp Alan when he went chasing after it to prevent it being blown into the water.
As time passed the clouds became thicker until we could no longer see the Sun at all and George also lost sight of the Moon. By 17:00 it looked as if we were fighting a losing battle and I had Lorenzo fixed on Lion’s Head giving visitors a clear view of the people sitting and walking around up there. Shortly after 17:30 we decided the weather was not going to clear so we packed up and headed for home.
The only consolation was that there had been no dew so Lynnette and I did not have to unpack and dry everything before packing it all away. However, despite the unfavourable conditions we managed to service just under 300 visitors during the course of the afternoon.
We can only hope that the 09th of July, which is when we are scheduled to set up on the Pierhead again, provides us with better viewing conditions.
Lynnette and I left Brackenfell at about 10:00 under completely overcast skies. It thinned in patches at times, but in general the prospects for viewing the Sun or the Moon, which was due to rise at about 14:00, seemed pretty close to zero.
At the Waterfront all the access arrangements made by George Moolman (Manager: Events V&A Waterfront) worked very smoothly. Once we had parked the Vito we inspected the site we had chosen on the Pierhead and decided on a tentative layout for the telescopes, poster A-frames and other paraphernalia associated with outreach events. Auke and Wendy arrived after a while, followed by Dirk. As soon as we had agreed on a final layout we unloaded and took the vehicles back to our allocated parking bays.
By shortly after 13:00 we were ready for action, but our targets were hidden by the clouds so what were we going to show the visitors? People, attracted by the telescopes and posters, approached us to find out what it was all about and we had to explain that we could not show them the Sun or the Moon, as advertised, because of the unrelenting cloud cover. Auke and Dirk got their telescopes [“Walter”, a 5-inch refractor and a 5-inch Schmidt-Cassegrain] lined up on the lower cable station and used the image to talk about how telescopes worked but, despite muttered incantations and explicit and generally unprintable expressions of displeasure, the clouds kept the Sun and the Moon well hidden.
As the afternoon wore on the clouds began to thin and we were allowed fleeting glimpses of the Sun. Every time this happened there was a flurry of activity as Lynnette, Wendy and I attempted to get “Maphefu” (8-inch Dobsonian) and “Lorenzo” (10-inch Dobsonian) aligned on the Sun only to have the clouds maliciously close in just as we almost had it in our sights. Then, finally, at about 16:30, the clouds parted and we could actually see both the Sun and the Moon. Maphefu and Lorenzo were equipped with solar filters, so Wendy and I could show visitors the Sun and some very nice sun spots, while Auke and Dirk concentrated on the Moon. When the Sun set behind the Ferris-Wheel I switched Lorenzo to the Moon and, as soon as it became dark enough to see Jupiter, I switched targets again.
For most of the rest of the evening I kept Lorenzo on Jupiter while Wendy, Auke and Dirk focused on the Moon. By 20:00 dew was becoming a problem and it became evident that we would have to consider packing up. Mars was very bright and eventually Saturn and Antares also became visible as they climbed high enough to escape the effects of the light pollution glare over the harbour. Crux and the Pointers were visible all evening as were Sirius and Canopus. By about 21:00 the dew definitely had the upper hand so we had to pack away and load all the wet telescopes and other stuff into the vehicles and head for home.
Obtaining an accurate count of the number of visitors was, as is usual, quite tricky because one has to be careful not to count the same people at each of the four telescopes. Lynnette and I both had counters and we counted just over 400 visitors, but our count is usually a bit low and the actual figure could be closer to five hundred. We also asked visitors to sign our visitors list and collected 282 names, which is definitely less than the number of visitors we had. It is surprisingly tricky to get people to sign the lists. Some people just flatly refuse and the telescope operators find it difficult to work a telescope, explain things to people and collect names and signatures at the same time.
All in all the afternoon and evening were quite successful despite the clouds. Many of the visitors also showed considerable interest in our poster display and quite a few promised to return in June when we will be set up again on the Pierhead, hopefully without clouds. Our dates for astronomy on the Pierhead at the V&A Waterfront, weather permitting, are;
Saturday, June 11th. / Saturday, July 9th. / Saturday, August 20th. / Saturday, September 10th. / Saturday, October 8th. / Saturday, November 5th. / Saturday, December 10th.
The next day all the wet things we had loaded into the Vito at the Waterfront had to be dried before we could pack them away. Banners had to be unrolled, chairs and tables taken out of their bags, A-frames unfolded and eyepieces and finder scopes inspected for signs of moisture. Even our folders with the laminated A3-posters had to be taken out of the sleeves and individually dried.
