I need some help.

I have search the internet and cannot seem to find the solution to this problem.

On the image below you can see diagonal bands running from bottom right to top left. The image is of an active region on sol. I have tried rotating the scope, the camera, the diagonal and the barlow. The bands stay in the same position and do not move. Can anyone suggest what the cause might be?

Initially I thought it was the camera, but given the bands do not move, I can only assume that this is a software related issue or an RF problem. I am certain it is not anything to do with the scope. However, I would appreciate any advice to the cause of the problem.
