M31

[MickD]

Old favourite, imaged this a few times....but first time trying a mosaic in Pixinsight.

Details are:-

Two panes, LRGB mosaic. Each pane is:-

Lum = 20 x 200sec Bin1

R, G, B = 8 x 120 sec Bin 2

Imaged in January with my Atik 383L + and a WO FLT98 scope.

The moon was up when I captured one of the Blue channels (first attempt was ruined by cloud) and it made balancing the gradients a bit difficult (the right-hand side is a bit darker than the left).

It was also a bit of a test to see how little colour data I could get away with.

Nice M31 in Panavision. Its nice to capture it in widescreen with just a couple of panels.
