THe 12.5 f-9 newtonian proved to be too difficult to use and was abandoned. A new devilish thought entered my mind and I realized that big tube would make a great start for a big classical Schmidt camera. As usual, my great friends came to my rescue. Dave Erickson and Ken Hebert are two professionals and have had a great past. Dave is one of the small group of people who built the corrective optics for the Hubble telescope. Ken had a part in many things and once told me he worked on the original scope that went to Mars many years ago. These guys agreed to build the optics for the Schmidt. It has a 12 inch corrector made by Dave and a 16 primary made by Ken. The focus is 55 inches and a 4x5 plate is used. It is therefore about f-4.5. It covered a 4x5 degree field and photographed deep with hydrogen sensitized 103aE plates. At this long f -ratio it could photograph deeper than short f-ratio Schmidts before sky fog ended the exposures. THe super dark Alpine sky and the longer photo times resulted in some far out stars, etc. Evered and I bought the Palomar Sky Survey. He took the blue and I got the red. Printing the 4x5 plates out to 8x10 made the prints almost the same scale as the Palomar. You needed a binocular headset to see that my Schmidt came amazingly close to what was on the Palomar prints. THe smaller field of the Schmidt brought the need for a different guider set up. I will post about this later, meantime look at post 55 to see all the results of many past different projects. I had a good friend who lived in Nutrioso who was a top level guy at NASA. Glenn said it reminded him of an English research lab with all the hanging wires, tubes, etc.
