M48

Open star cluster M48. Captured on March 28 while testing the ZWO ASI AIR PLUS. Taken through a Sky-Watcher bkp2001 telescope on an HEQ-5 PRO mount with a SharpStar 0.95x coma corrector on a Nikon D5300. The total integration is modest. Stacked 53 frames at 10 seconds each, ISO 1250. Total integration ≈9 minutes. Separately, without the ASI AIR, I captured darks and biases. Using PIPP, I converted them to fits to stack with the lights, but DSS started complaining that the image sizes were different (even though they were the same) and so on. Therefore, only the lights were used in the stack, without calibration frames.
