North American Nebula in Cygnus
This is one of my favourites had a couple of attempts on it and finally got a very nice clear night. 34 lights at an ISO of 1600 180 sec exposures guided and processed in PS.
And for comparison here is the same subject done with my modded 450d 40main subs with 20 darks flats and bias and ISO of 1600 and each shot was two minutes long also I used dithering in APT to get rid of the noise which works really well.
