Not being versed with the imaging capture software for the DMK, what is the histogram showing (hopefully values between 0-255...8 bit)?
Also are you estimating the exposure by eye? The dark adapted eye can think something is bright, when it is not really. I always let my histogram read out in my capturing software to tell the truth (0-4096...12 bit)
I also do not touch the setting of brightness / gamma / contrast. I want as "natural a caputure" as possible.........ie I do not want to try and capture at 60fps and at first get a dim image, then try and "artificially" boost the signal by upping the brightness / gamma etc.
Do you have a single frame from one of the runs before registax played with it?

My setup is:
8" SCT
DMK 8bit camera
No filters
The histogram on the capture software shows between 0 and 255.
I estimate the expsoure by eye but always keep a watch on the histogram. I've been capturing all my recent Joop images with a 1/60s expsoure shooting at 60fps. I then usually adjust the Brightness, Gain, Gamma so the histogram is properly exposed.
Here is a single frame and the final image from an imaging run on the 30th. As you can see in the final processed image there is severe onion rings.
