10 inch Fork with Cold Camera by Mel Bartels
After my 8 inch f/7, my
second serious telescope was a larger faster scope, a 10 inch f/5. The tube needed to
fit into the backseat of a car. I often drove to the top of the pass:
note Mt Washington in the background from Potato Hill, one of my
observing sites. For tracking I used a drive built from a homemade gear
with teeth made from wood putty. The motor was an AC synchronous motor
with variable frequency control. With careful polar alignment I was
able to guide for several minutes. I developed my own B&W and color
film and produced my own enlargements. I built a cold camera that
accepted rolled film. It worked quite well. I had a lot of fun both
observing and imaging with this scope.
