Question wrong colors
« on: 2015 December 02 09:13:04 »
Hello Everyone

What Have I done wrong? Three images below all of Cirrus NW Part Nebula 18 5 minute images taken with Takahashi FS78 at F 8.1 with SBIG STF8300C and used niomal Preprocessing routine (Manually). I have been using the same routine on all old images and this time I seem to have a color issue problem (same debayer routine as all prior images).2 images 1- post a LRGB combine with a synthetic luminance and 2- have LRGB combine (in non linear state) and a scnr noise reductionn on the green. Even the image just after integration show a lot of green stars with just an auto stretch.

Why so many stars orange or red??

Will need 2 post to show the 2 images
