Thank you Paul,Originally Posted by Paul Fitzgerald
I ordered three other lenses from Surplus Shed. The plano-concave of -100 mm FL and two plano-convex 100 and 101 mm FL. The 101 one is coated. They aslo should have the same diameter and mine do not have. I think I could just use a fixed stop in front of the front element, which is wider few mm. I also orderd an iris from them. The original design calls for 100 and -100 elements, I am not sure if 1mm makes a difference, I will try both combinations and probably it would be nice to have a coated lens.
I think I will make some temp. housing for the lens made of PVC tubes, take few test images and if I like the results I will order nice, custom made metal helicoid barrel.
kind regards,
Jan
