M1 / NGC 1953 / The Crab Nebula in RGB

M1 (Crab Nebula) RGB Heutech LPS

Full pixel crop from previous.

Finally have a got the colimination under control. It wanders about 3 arc/sec or so

due to tube flexing which I still have to come up with a solutions for. This is all new

data with the new alignment and using a Heutech LPS prefilter. There is a very noticible

improvment using the LPS filter on the blue channel in particular.
