We've collected a good amount of signal, but there seem to be few details. Maybe the galaxy wasn't stretched enough during processing? Check the two versions in my profile—the second one is roughly like your total integration.

This is actually only my third attempt at photographing deep-sky objects, so I still lack experience both in shooting and processing the captured data. Also, I’m still working on calibration frames—I haven’t taken flats yet.

The main thing is darks, without them you can't start processing the curves - everything will drown in noise.
