Description

After lots of stuffing around trying to get my flats to play ball with my LRGB processing I made my own light box (to avoid the flat panel directly bouncing light around the tube) and hit the road, heading to a local dark site. The location turned out to be highly populated with holiday revellers but I found a quiet spot with an Eastern view and got some data on this wonderful galaxy and the many that surround it. Again quite short and noisy but I was happy with what I managed to get.

Culled some useless subs and tired to avoid adding too much noise

C

Now the background galaxies are less burnt out and even a hint of colour

D

A crop of the central area

G

Oops this is the warmed up one and slightly rotated.

O

Slightly richer colour

P

Straight out of PixInsight

Revisited with selective deconvolution and noise reduction
