I work as optical engineer and I plan to use an amateur telescope for one of my projects.
The telescope must have long focal length, say a Maksutov with 2700 mm or a refractor + Barlow with f=3000mm. . All of these are rough numbers, no need to be exact.
In order to simulate performance using Zemax, I would need the design of one of these telescopes or at least the "black box" design. Does anyone here have contact to the manufacturers, or hace one of those blackboxes??
Thanks and starry nights !!
