Description

Started this on the 15th August 16. Got the final 2 panes on the right hand side done last night 18th September 16. Roughly 3 hours a pane. The trunk bottom has only 2 hours though.

Fully processed in Pixinsight using David Ault's DNALinearfit script and the GradientMergeMosaic programme.

Could be a while before a full colour version appears.

Rev B: A 23rdOct16 reprocess of A using a tutorial of Basic Pixel Math by Gerald Wechselberger.

http://www.werbeagentur.org/oldwexi/PixInsight/PixInsight.html

Image B is the final LHE image ( which I quite like ).

REV C: Is the resulting pixel math blend of A and B. It has definitely given the whole mosaic more contrast.
