53 x 2m subs

Canon 450D all filters removed, Sigma 120-300m f/2.8 OS + 1.4 teleconverter for 420mm f/4. Astronomik CLS-CCD filter.

Processed in PixInsight with darks. Finish off in PS Elements.

This is the longest focal length I've seriously used for deep sky imaging yet. Was hoping to pick up the texture behind the horsehead but looking at other photos I think I need more resolution to really pick it up than this widefield attempt. Might try the ST120 on this next time (600mm f/5).
