This is an integration of 8 x 1200sec ( 2.66 hours) exposures using an Orion Starshoot Pro V2 OSC 6MP APSC camera and a 10in F10 SCT @ F7 via a Starizona .63X SCT focal reducer. I autoguided the image with an OAG using Astroart's Full Frame guiding.

PreProcessing:
Sigma Sum
Colour Demosaic = 4 gradient 1x1
5 dark frames, 10 flat fields, hot pixel removal.

Processing steps:

1) 20 x LR deconvolution using a Gaussian 1.0 PSF
2) DDP
Gamma 90
WP 20
BG 0
Sat 29
WB 50
HP
Sigma 2.45
Strength 30

3)Gradient Filter
LP 50
