It seems that I am headed down the Amature telescope making path. Has anyone in the group gotten their hands dirty with this? I’ve been reading lots of forums and blogs of other peoples projects with reflectors & refractors. My craftsman skills are mostly wood working related with some tangential metal working but I’m intrigued by the Schupmann design of scope. I think it makes sense to start with a small refractor though. I’m wondering if anyone has any experience in this area and has any advice or sage wisdom as far as things to avoid, common pitfalls, design considerations. Ideally i’d like to build scopes that can be for visual and photography which is why the Schupmann design is incredibly intriguing. I feel I should start with already purchased lenses for a short refractor and work my way into grinding my own for a Schupmann down the road. SC’s and RC’s are also tantalizing to attempt as well. I’ve been getting lost in YouTube rabbit holes on lens and mirror grinding and building testing equipment. Hope all are well and praying for some clear skies!
