The #astronomy group I associate with, #AGWA have a target of the month each month. This month it is #C63 , the #HelixNebula . Now over the past few years I have shot this target a lot. So I am now gathering together *all* my session data, going the Full Tim and stacking it all. I don't know how many hours it is. Lots. Wish me luck! #astrophotography #Astrodon #dwarf3
