Swindon, Wiltshire. UK

GSO 8″ Richey-Chretien Optical tube, Skywatcher NEQ6 pro mount,Atik 383L+ camera, motorised filter wheel and Astronomik filters.

Data collected on two nights the 29th november and 4th december.

One of the first deep sky objects I tried to image with poor results. Too difficult for a beginner.

This is best my image of this nebula yet. Started to pick out the dusk lines with only 5 minute exposures.

LRGB image with 8 hours 10 minutes of data and 5 minute sub frames. 50 x 5min Lum, 16 x 5min Red, 17 x 5min green & 15 x 5min blue.
