I bought ZWO ASI 2600MM Pro

I performed a series of tests and I found that it has random banding noise in any gain a used, 0 or 100, at any offset I used, at any USB speed I used.

I performed all the technical solutions together with the seller TS, but no improvement was observed.

Those stripes, random noise, still appear no matter what type of cable (powercables do not cross each other), charger, updated driver, computer, windows I used.

The lines also appear on the final stack, and cannot be removed by calibration, the dithering does not work either.

I sent back the camera to the TS technical service and it stated that it has a problem with the sensor and needs to be replaced. He sent me another zwo ASI 2600MM.

The replace camera they send me is even worse!

The camera works only if its powered with current, how so? The first camera that I have returned was working!

For any Gain I used (0/100) and Offset, random strong noise appears, (this time is strong) no matter what type of cable (powercables do not cross each other), charger, computer, windows I used.

The lines also appear on the final stack, and cannot be removed by calibration, the dithering does not work either.

I asked for the return again!

I really wanted this camera based on the fact that it is very good. That's why I invested so much.

Is it normal for this model ZWO 2600MM to have random banding noise?

The camera will sort of work for short exposures powered only by the USB cable, but to cool the camera (which you should do) and to take normal longer exposures, you need to attach it to a separate 12v 3a power supply.

Are you doing that, powering it with a power supply?
