I've been using a big dobs for a couple years now and know my way around them somewhat, but I'm in a new place now and can't manage bringing that wonderful giant with me. It turns out to my great delight someone in the area is selling a used C-8 but I have virtually no experience getting an idea the quality of an SCT's optics.
Any advice for an SCT newbie looking at picking up a used scope? Anything in particular I should be looking for?
Thanks a lot guys
