Description

Been a few weeks since I last processed.
The Helix Nebula is one of those iconic deep sky objects (planetary nebula) that draws you into the hobby.
A lot more difficult to process than I had anticipated! Happy with the result though I will revisit with some much longer exposures for the outer shells.
For those at the International Astronomy Show 2017 I have used both the Lum and the colour stretching approaches I presented.
