Question

The overview image is bright on one side and dark on the other side (as shown). What can I do to fix this and get a better overview image?

Answer

This appears to be a problem with the flat field image used to flatten out the overview image. There are two things to try:

1. Recalibrate the Overview Camera.
2. Check to see if a filter with flat field correction is applied to the overview camera.
