heres a so so image of the Helix in Ha.
2x 18 mins, hurried proceedure to try and get at least 2 shots before cloud rolled in, moon 3/4 full.
7 Nm Baader Ha filter 10 inch F5.6 scope, modded 350D. Warmish night, lots of noise in original shots, used a dark taken a few weeks ago, but was keen to try the Ha filter on the Helix with the 10 inch scope.
I will need quite a few more shots under better conditions with several darks taken at same night to get a decent result.
I wish I had Strikers cooled camera
