Focal Position

Another of my apparently rhetorical non-rhetorical questions. Telescope designs sometimes include a field corrector/flattener. Is there some sort of mechanical

Schupmann telescope Design?

saemark30 — Fri, 26 Apr 2013 19:41:31 GMT

Anyone tried to model a Schupmann telescope all spherical design? I am interested in something around 10" F/10 and have access to Zemax. With the

I spent a bit looking at a problem given on one of the lists. Normally, "field correctors" for reflectors have a note that specifies that the focal ratio is

Hello all. I joined this group hoping people on here can answer some "simple" questions like this one. I'm getting on fairly well with oslo edu but 2 things

... Or, if you accept a bit more compromise, perhaps especially in glass selection, the geometry could be even more simple: Title: CookeT01-32y 100 mm f/12.4

Interesting geometric constraints (design CookeT01-14y in the rflrs files subdirectory), unless I've missed something that I shouldn't have.
