Description

First attempt at an Ha image of the Horsehead. My feeling is that I could do with more subs, so will have to do a second night. I shot at gain 200, offset 50, with 300s exposures. I would be interested to hear thoughts on whether lower gain and longer exposures or taking lots of shorter exposures at this gain would yield better results with this camera in Ha.
