The Swan Nebula in Ha 7nM
Hi,
I have never really had a go at this object so on Saturday night I tool 18 x 10 minute shots using a Hydrogen Alpha filter 7Nm.
Taken through a William Optics Flt 110 and guided with PHD and stacked using DSS and processed in Photoshop CS3. Camera was a QHY-9 at
-20c. Darks applied but I have not done flats as I am struggling using my light box that I can not turn down and I don't really understand how to use EZCAP(program that came with the camera). Weather permitting I will have a crack at some colour ones of this tonight.
Feedback welcome.
Mark
