Noise banding

[Cleon_Wells]

I think I fixed my banding noise problem by aligning the guide camera with the RA axis. I had not aligned the guide camera in this image of M51, check out the last image in this thread.

For this test, I took a set of subs (24) the other night with temperatures around 90 degrees, the target was M63. Now I’ve got hot pixels that are not removed by integration but no banding noise. 8>)

Use the DefectMap process or the CosmeticCorrection script to remove those remaining hot pixels You have to apply that just after the image calibration, before registration.

Carlos, thanks for the reply, I thought I would have to go this route after I fixed my strange drift problem, caused by my miss aligning of the guide  scope camera. I assume this problem also changes with the distance of the guide star used from the target.
I think it would be a good feature to incorporate the Defect Map process with a Check Box, in the Calibration process.
