Hi! I've been imaging with a wide field set up of 80mm apo refractor + avx + dslr.
And I see a 6" RC sold just for $400 and I was thinking maybe this could be an economical add for my imaging choices (it'll only be for DSOs)
I'm here to ask for advises on my impulsive, dangerous thoughts...
I used to image with a 6" f/5 Newtonian, which weighs about the same as a 6" RC. My avx performed well with guiding error around 1.5 arcsec rms. So I don't worry too much about guiding.
I also have a x0.8 flattener/reducer for my refractor, which I could try for the RC. I have a laser collimator I used for the Newtonian but will I need it for an RC?
I hear that the collimation is difficult with RCs... How hard is it and what kind of collimation tools do I need?
In particular, I am looking at Astro-Tech's at6rc, just because I have a good experience with their at80edt.
Any advises or thoughts? Should I just walk away from the temptation and continue living the easy life as a refractorer?
Thanks so much in advance...!
