Light leakage?

[ampleamp]

I am renewing my darks library. I see i have a column defect but please could someone confirm if the following darks exhibit light leakage. I don't know enough about this but the following is a 1200s dark frame showing lighter patches towards all the corners and along the top line.  

If it is normal and I just haven't seen this before then fantastic, but if it is light leakage I will have to try to track it down.

Thanks for looking

I'm not sure if this helps or not, same sensor but different camera make. This is a 1200 second -20 degree C Master Dark (22 subframes combined in average mode) from QSI 683 (KAF8300 sensor). I don't see those hot regions in my own darks.

Hi Steve,

sorry, I should have said, this is from my H694 camera, not the 383

Sorry, Alistair, I had assumed the 8300 by the aspect ratio  - you know what they say, 'a little knowledge can be very dangerous'!

Not a problem Steve,  I frequently feel that my level of knowledge barely reaches even a little

I have had an email from Terry at SX saying that the lighter areas are amp glow and can be adjusted. As darks apprently they will be ok, but aesthetically I will put them right anyway
