Question Ghost stars in ST8-XME

Hi all,

Does anyone have advice on dealing with ghosting in CCD images? My ST8-XME exhibits significant ghosting.

For example, I will take one 60 second exposure, slew to another object and take a second 60 second exposure. It is common for the residual image of a bright star in the first exposure to still be present after 3 subsequent exposures.

It's a real pain. I'm hoping others at least have the same problem and perhaps have a workable solution?

Thanks,
Roger.
