Here's my latest effort (taken last month) of the Horsehead and Flame nebulae in the Orion belt region.
I wanted to try something a little different this time to maximize my exposure time so I used two cameras, the 20Da and a standard 20D.
This allowed me to image through one while the other was taking darks and then swap them over and do the same again at 5 frame intervals.
I was thus able to take as many dark frames as light frames for each camera in that space of time.
In the end a total of 20 x 9 min subs were combined (3 hours) at ISO 400, 10 from each camera.
Using the two cameras gave a nice colour balance in the end I think.
The scope used was the TOA 130 guided by PHD using an ST80 and Orion Starshoot autoguider on an EM400 mount.
Stacking was done in Deep Sky Stacker and processed in PS CS3.
