This image is 8 x 30secs 8" Newt. with DSLR.
Incidentally, if your darks are of the same duration as your lights, you don't
need bias frames, as darks contain bias data.

i usually get stacking artifacts as i don't guide yet and the images wander a bit. this is not cropped very much at all,less than 20 pixels on the bottom and left side i think. Yes i totally agree its missing more red stars and is over saturated, i will try to watch that in the future mate i love your image btw.
and thanks for the info on bias frames, there are so many types of calibration frames i get confused
