This image is LRGB, only. If you do a stretch
of this, you can see I picked up some IFN...even with my light
polluted skies. Lost an R frame in this session unfortunately, so carefully managed
color. Also, combined a slight amount of color from my 2013
session (also with TOA and using previous QSI camera).
