Hello, what brand filters fit the Ultra Slim CFW3?? 5mm is not a lot of clearance after the 2-3mm filter thickness...

I think it has no problem, the bandings are not very obvious.

Can you send me the parameter?

Gain, offset,exposuring time and temperature?

We can take some dark frames and compare them with yours.

Best Regards

Gain=120
Offset-14
Exp Time=300s
Temp= -10

Thanks.

Hi,

You can take two dark scenes and subtract one from the other.

See if there are still bandings.

Best Regards
