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.
