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).
