#Astrophotography question. Do any of my star gazing friend had any experience with a 6” Ritchey Chrétien. I am thinking of getting one but there are so many contradicting statements about them out there. Several questions I have include 1: I use an ASI183mc pro, astronomy tools say I will be slight over sampled, should I be bothered or what do you do? 2: Guiding; my Astro shop is saying put a 32mm guide scope on it with my asi220mini.
