Astro Post Processing Problem
« on: December 26, 2017, 11:35:36 AM »
Hello Everyone,

I'm experiencing some weird behaviours doing my first astrophotography test shoot.
I did post processing before and I though I'm confident doing it for wildlife and landscape.

Please check this picture: Around many stars there are small square areas where the weight balance is either off to blue or to orange.

The balance is now k3942 and the RAW file was taken with k5050. (if the whitebalance is back to k5050 this problem does not exist.
I used my 7D mark2 and the Sigma 17-50mm 2.8 EX lens. (17mm, 15 seconds exposure and ISO3200)

Did you have this before? I already tweaked every button in lightroom but so far now help.
Could you help me out here?

Cheers

Steve
