Celestron c11 sct, skywatcher NEQ6 pro mount, Canon Eos 1100d self-modified and Astronomik CLS CCD clip filter.

Had to be up early to start my imaging session on this galaxy. Happy with the results especially the detail in the spiral arms. I was surprised my Canon Eos was able to capture this amount of rich detail.

19 five minute light frames at iso1600. 20 dark, bias and flats. Deep sky Stacker and Gimp. Cropped and reduced by 72% to get image size below 2MB.
