Tomas had brought a William Optics refractor, which he tested on a borrowed mount to see if it was stable enough. It looks that way.
Tomas has a photosite with astrophotos, only in Swedish:
There was also a quiz walk. Here's Gunilla reading carefully the first question. The questions were tricky but Gunilla is skilled and got the third price. Me with my astronomy education got nothing :-) . The third price was a photo of the comet Hale Bopp taken by the photographer Mats Yderstig. It was taken in the year 1997 with a Hasselblad medium format camera with a 150mm lens.
The sixth question and now we have come to the railway bridge. More headache, how fast is Pluto's average speed?
Twelfth question and second bridge. Was it here they asked about how many kinds of nebulas there are?
One question left and we are almost back to Berga Gård again.
After all these questions we had a break for lunch. We also had time to talk to all the other astronomy enthusiasts. It was very nice to see the face of who we are talking to, not just chatting over the internet. Down right you see Joel, he is very famous to make high precision mirrors. Very big mirrors too, I belive 30" is the biggest one yet, years of polishing!
Anders in middle had brought two telescopes. Here is the smaller Celestron 127mm equipped with a binoviewer. We looked at the life saving buoy and flag bar's bud, it looked impressive. We felt sorry for all those who had brought all their equipment to VSP since there were no clear sky either nights.
AstroSweden had brought a lot of books, a lot of people were interested in them.
Professor Mark Pearce talks about his research at KTH. They had used balloons to lift up their X-ray detectors to 40 kilometer. They must reach these heights to detect X-rays. Very interesting and I talked a lot to him afterwards.
After his talk Mark got an astronomy photo from VSP.
If you want to read more and deeper about Marks research projects you will find more information here:
Pär had brought his Sky-Watcher telescope. He had some problem with star calibration. This was an opportunity to let the team from AstroSweden help him direct. Modern astronomy equipment are very advanced and it can be very confusing to set them up correctly in the beginning.
Per had brought some used equipment for sale. I looked a lot at this goto mount, maybe perfect to my balcony, only 6000 SEK, but it was sold just a few hours later.
Anders Wettergren held a talk about the constellation Orion and the stars and nebulosity it holds.
Anders Wettergren, intensive after-talk-discussions.
Christoffer Svenske talks about Jupiter photographing. He holds the monocrome ZWO camera with a mounted filter wheel that he uses. A fast camera that needs a very fast computer to handle the transferring of data Christoffer explained. In the background is Firecapture, one of the softwares he uses. Very instructive and impressive how high resolution it's possible to reach.
Here are the softwares Christoffer use:
What I can see they are all free to download.

Now the clock is half past ten pm and we all are tired. We say goodbye and take the car back to Sunne where we live. There were also a talk the last day at ten a clock am, but we had a long drive home in bad weather so we skipped that talk. We also wanted to have some spare time to look at interesting places on our way home.
