had a go at M101

Not sure why but I never processed the Messier 101 (M101) video captured, with the centre MallinCam, back on 2 Aug 2011. I had a quick go...

North is top-right; east is bottom-right.

From a single frame, extracted (with IrfanView) as a BMP.

To a stack (with DeepSkyStacker) of 16 frames. Quick levels and curves in Photoshop.

And then a stack with 160 frames.

Thought I had taken some dark frames... Alas, the stacking was with lights only. That amplifier glow is sure annoying.
