- Star reduction in PS using mask created in PI
- Colour Enhancement in PS using a clipping mask created in PI to protect stars
- Enhanced the dark lanes in PS using curves and a layer mask

Tough area to process due to all of the freaking stars. Star mask creation using contours and then applied a morph transform which helped control the area a little. May need some more tweaking.

These wide fields of view definitely present a whole new set of unique challenges and it has been fun learning.

Comments and criticisms welcome.
