Aloha Kurt The AllSkyCam is my 3rd version of this idea. It all started when I saw a fellow on line build an ultra-wide medium format camera by adapting pieces from several camera, at the same time I was in contact w/ Dennis Anderson (Auroradude.com) in Alaska and he talked about his 4x5 Toyo adapted w/ a 30mm Arsat for near 180 hemispheric photos. I then liked the idea, bought the Arsat lens on eBay and took apart my Sinar P to use some pieces for a test. The format frames were attached to a 4X5 piece of aluminum, I cut a bellows down to 3-4 pleats and began to play and learned that getting exact focus w/ a non focusing camera is not the way to go. I then bought (again eBay) a Sinar Alpina, modified the standards and mounted the whole affair onto the 6" extension rail where I have focus and a nice solid package. This camera mounts onto a Celestron CG5 drive and I have been having fun and non successes ever since. No plans, just some photos and a whole flock of fun ................... Aloha Rob
