strange superbias
« on: 2019 September 24 14:40:49 »
Hi all,

Ive recently created a superbias from a stack of 100x0.001s images from my zwo 071. Im wondering if the dark area to the left and right hand side are normal as my superbias from my canon 6d was relatively uniform.

Thanks ken

Hi Ken,

Do you see those dark areas in the individual subs as well?

Hi Wouter,

The dark areas don’t appear to be visible in my subs. There does appear to be a strange pattern forming in the master bias and super bias. The top and bottom edges are bright and the left/right hand sides are dark. ???
