Hi everyone.

I took this image of M83 tonight with a new GSO RC8 i recently purchased.

I was a little disappointed when it came to processing.

I havent gathered much data:
L 60min
R,G,B 6 min each.

Can anyone explain to me why i have such severe uneven illumination and why the majority of the illuminated region isnt in the center?

I have a William optics 0.8x filed flattener also installed.
could this be the cause??

equipment:
Heq5 pro
GSO RC8
WO 0.8x filed flattener
QSI wsg683-8

Thanks for your help.

John
