Thanks Matt & Mike.

With respect to bird's research, I was thinking we left that as waiting to hear further from bird on the DMK gamma question. I shoot at gamma register 10 (1.0) for Jupiter and was using 13-15 for Saturn. Compared to the color Unibrain camera I have it seems to me that 1.0 gamma is about right - I would be surprised if it were that far off.

According to bird, imaging at anything other than gamma 1.0 leads to some data loss. I understand that Mike shoots at high gamma and corrects it later in his IP. Would that not effect a loss off information?

It occurs to me to measure gamma, one would need a standard test target illuminated at a level to simulate an astronimcal object, as there may be an interdependence between gamma, gain and exposure time.

To clear this up, can an IceInSpace collective effort be made to resolve this issue? If anybody is in communication with bird, perhaps we could get some clarification.

Thanks guys for your help. The contributions by this forums contributors speaks highly of your love for this hobby (or livelihood in some cases).
