Strange dark frame pattern.

Hi all,

Please look at the attatched dark frame taken from my brand new ST-8XME with KAF-1603ME Class 2 CCD camera. I'm new to this hobby and the eliptical shape cluster of dark currents at left upper part of the CCD make me worry. Is it normal for this class of CCD or it is defective one?

Thanks for all comment and suggestion,
Wiwat T.

Looks like frosting to me. This would be unusual in a new camera -- the desicant should be fully charged. You may want to call SBIG and talk to Mike Barber about this. Either that or post your image on the SBIG Yahoo!Groups site.

Take several dark frames. Sometimes there is a left-over image from a previous exposure that appears in the first dark frame.
