Hi Marin,

This is really good. I searched Helix images on the net when I was checking on mine. Your details were just as good as best ones out there. I thought long subs would be better but yours with 3min seemed to be just fine (even at F5), and 3nm filters do work well for nebulae under B8 skies.
