The camera is the Watec WAT-120N which is an integrating video camera. It takes images at 25 frames per second and can stack from 0 (no stack) to 256 frames in it's memory. To meet the requirement for TVs, VCRs and the like it outputs the stack at the rate of 25 (stacked) frames per second.
In this case I was stacking 32 frames, making and exposure of 1.28 seconds with almost instant download making for zero dead time.
The method I used to make the quick grab was to simply grab all the multiple stacked images. So my plot has 32x the amount of points.
Tonight I'll set up the software to grab 1 stacked image to PC for every 32 that comes off the VCR. This should give a cleaner result.
I'll also process the FITS from the 8"LX90/DSIpro.
