For all of the Pro Cameras:
Does the Image contained in the DDR Buffer download while the next Image is being Exposed to the Sensor?? Or does Exposure have to wait until the DDR Buffer is Offloaded??
Is there the opportunity to Capture multiple consecutive images to the 256MB DDR Buffer before emptying it via USB Cable?? For the 1600MM-C, there is room in the DDR Buffer for at least 7 Images.
One could see a use for 7 consecutive Exposures then Downloaded whilst the AutoGuider performs a Dither, saving substantial time for additional Exposures. (1 dither ratio would be just fine for the high exposure count common for such a CMOS AP Camera).
