A few months back I set the goal of 12 hrs on M83. This may well be the 5D's final proper go at deep sky.
I've done a quick rough stack using DSS, 168 frames, 12hr 55mn exposure time.
Subs are over various nights at different moon phases, exposures and yadda yadda.
Darks, Flats and Bias are used.
I've spent well over 24hrs editing the stack as practice. I want to cull the data more selectively with pixinsight and try a 3rd edit, but I dont feel I'm doing the data justice so far as it is.
It seems very noisy? Am I expecting too much from the camera or am I probably making a mistake in the editing process?
