high rejection areas pac man nebula

[diurnal]

Hi
 
I just wanted to see if anyone has seen this. I'm not sure if it's my darks, flats or biases, or just something else. I have some photos here.

this is the stacked frame, i looked online to see if there is anymore nebulosity in this areas besides the pacman in the middle, but didn't see any. I stacked the photo in Deepskystacker as well and it turned out good.

here's some of the rejection patterns

this is the low rejection areas.

this is the high rejection areas, is this normal. it look like its picking up nebulosity all over the area. I'm probably doing something wrong, has any seen this pattern before?

well the only other thing i can think of it being would be the moon. but i dont think it was up while taking my light frames.
thanks.

ps pixinsight a pretty powerful program, i'm really getting the hang of it but having problems here and there.

this image looks like it's from an OSC and it was not debayered…

thanks rob

i think that did it. for some reason i quit checking "CFA" because i thought grayscale meant = linear data and color = nonlinear.
