ASI 1600MC-Cool strange lines on images

Post by mof1re » Tue Feb 26, 2019 12:13 pm

Hello, few last months strange lines appear on my images.
It's not an light pollution or similar problem. Lines is static even if i rotating camera.
Lines also can be visible on the flat frames, but flats do not removing lines from main stack anyways.
Any ideas, experience with a same problem?
On both frames camera have different rotation angles.
Example images attached.
Thank you in advance,
Best Regards,
Vladimir.

Hi Vladimir,
Can you check the optical system? please make all of them are clean.
It does not look like a problem of camera.
Thanks

I've checked and clean all optics, both mirrors, coma corrector, disassemble camera and dry "tablets", cleanup camera sensor etc.
And got the same result today, i've rotated camera and lines still on same places, that's why i think that problem is in the camera.
Flat frames fixing problem just partially. On color correction/saturation process lines is became visible.
One 300s (gain 139) frame is attached. Stretched and saturated.

Hi there, take flat frames and do calibration will remove this pattern.
