This is a stack of 8 images taken through a Celestron 80ED on a Vixen Polaris mount with CG-4 drive using a Canon S330 camera. The frames all have the same exposure in this case, which appears to be far less potent for getting a wide dynamic range than combining individual images with different exposures (as was done in the C5 stack I posted). This is at 50% resolution from the parent image.
