Flame nebula
This wide field shot includes the Running Man nebula at the bottom right, the Horsehead nebula just below the star Alintak in the center, the Flame nebula just to the left of Alnitak and the nebula called Messier 78 in the upper left. It is all part of the intense star forming region that is sometimes referred to as the Orion molecular complex.
This image consists of 50 100 second exposures, stacked in Photoshop CS5.
Canon 70D with vintage Takumar 200mm f 4 manual lens at f4. Stopped down to f 5.6 in front of lens with stepdown rings. This way I don't get diffraction spikes in the stars, which I don't find attractive in this particular lens.
IOptron Startracker pro with counterweight which made a huge difference in tracking accuracy with this particular camera lens combo.
Rigel systems star finder.
EOS utility for bulb timer and Canon DPP for quality checking on the fly.
