Problems taking flats with ASI1600MC-C

Hi all,

I tried to take some flats but the flats are having sone horizontal banding.

What ADU should I aim for and what exposure time is good?

( I tried for ADU 20000 with exposure time of 0.08 seconds. )

Could it be that my flat panel gives too much light so the exposure is too short??

Any help is greatly apreciated!

Yes, it's better to use longer exposure for flats.

Aim at 1 seconds. You can use sheet of paper or white t-shirt.

What kind of panel did you use for the flats?

Does it have a PWM brightness control? If so make sure its set to maximum otherwise if can give banding.
