Question Fog on the CCD? Desiccant Plug ?

G'day all,

See attached image. Perhaps someone with a CCD camera (specifically SBIG perhaps) could confirm for me if this is fogging on the CCD glass screen requiring the Desiccant Plug to be "recharged" ?

It was only less than a year ago that I re-charded the plug and find it strange that it's already needing it again after only occasionally being below -10. Also when looking at the chip visually I can't see the fog, but that doesn't surprise me so much as it must be very light.

Thought I'd check before I bother doing the recharge.

The pattern of "fog" changes between exposures slightly.

(I'm talking aboutthe fog effect - not M95 sitting in the middle, I know what it is )

Roger.
