Hello, sometime next year I am interested in a self build project-either an f4 12" newt or f5 10" -depending on mirror availability.
I want it to fit in my dome so would have to be max length about 1100mm and have a sturdy probably moonlite focuser.
This could be a truss design as my friend El Draco is building a huge Truss currently and I am hoping to pick his knowledge !
Weight limit would be scope and camera plus smaller scope (SV 60 frac) on PMX.
I am looking at suggestions for mirrors, for fittings, for design inspiration and for any pitfalls.
I have a basic ATM book and have seen the NEWT WEB design app (which doesn't seem to work on my laptop).
This is really to get more personal satisfaction than buying a bigger scope as I really like my 8" newt and a 12" f4 that had a small footprint would be about the best I could do in my dome. (and still slew it!!)
I know this is a brad ranging enquiry but I thought I would test the waters early to avoid financial mistakes.
Cheers
Graham
