Description

Helix Nebula (NGC 7293), taken with my ASI1600MM-Cool camera, through the 10" Imaging Newt. Imge consists of 25 x 60sec lights for each of the filters (RGB&L). Luminance applied as soft light with reduced opacity. Processed in DSS with Darks and Bias but no flats; colourised and layered in Photoshop CC.

Forgot to attach the Baader MPCC (coam corrector) so some coma is visible.

While processing in Photoshop it was possible to bring out the shock wave extending out from the Helix but there was not enough data acquired to prevent it from appearing grainy. I will add more data at another time and reprocess.
