Subject: [SBIG] CCD Ghosting

I found a paper describing this and have included a link to it.

Armin Rest - Publications - Residual Images in CCD Detectors - 02ghosting:
www.astro.washington.edu/rest/papers/02ghosting.pdf

It is a bit technical, however the introduction tells you most of what 
you need to know. 

As an aside, I have not found this mentioned in any of the most 
popular books on CCD astro imaging.

It will change my image acquisition techniques.

Thanks for all the reponses.
