Some lovely full discs, certainly 2 have much better surface contrast than the others :bow

Thanks Alexandra

I agree, 2 scopes are slightly better. However all these OTAs perform well in H-alpha. It is important to have a good etalon (the one I use is a Pre Meade SM60 + coronado BF30) and a focal ratio of F/8 or higher
