Nice M83 Ray.
I assume 1x1bin. I like the disc gas definition. Can you run put up the 30 sec version? With your Gain set at 100, what offset were you using?
I have been reading up on Gain, Offset and Bit Depth and found this article by Carig Stark useful, not saying you need it, but anyone coming from a DSLR background to this camera might find it useful:

East coast low here so I am out of action probably until Tuesday at the earliest.
