Does the Dark pattern change with astro modification?

Recommended Posts

Hi everyone,

I have two master darks: one pre-mod, one after-mod. I can see certain pixels matching, but I fail to understand why that change happened or even if it's related? It bothers me how good/even the sensor was before, and how incredibly bad the center/left is now.

I can't seem to remember any other change the camera has gone through.

Any thoughts?

Thank you!

+1 for IR/Light leak

IR can penetrate plastics and if you replaced IR cut filter with one that passes more light - you might have IR leak.

Alternative is that you forgot to cover finder window.
