The lack of suitable guide stars can be a problem with a small telescope. And this was the reason for using my 9×50 finder. With my QHY5. I don’t have any trouble finding a suitable guide star. And the guiding is very accurate. I was guiding at 2.5 seconds last week-end. And imaging at 1200mm with 300 second subs.
