Description

I've previously imaged NGC 6946 with my Esprit 120 and with my C6.  This time I used my C9.25 at f6.3 with my 533MC camera.  My guide scope was too small for the focal length (50mm Orion f3.2 with ZWO ASI120MM mini guide cam).  When I get the time I'll replace it with something bigger or try OAG.  Transparency was pretty poor and seeing was horrible.   But I persevered and although I threw away a lot of subs, I stacked the best 108 minutes worth.  I used 2 minute subs.  Everything worked fine except the weather could have been better and I should have used a larger guide scope (or tried OAG which I haven't used in quite a while). Anyway, not a great image but this is also the first time I've used the C9.25 in about a year.
