Comet NEOWISE


Comet C/2020 F3 NEOWISE through a Pentax 200mm lens and the ZWO ASI294mc-pro on an iOptron Sky Guider Pro Mount. I captured this image last Friday, July 17, 2020, at appx. 0300 UTC, from Chazy Lake, New York. I took 53 x 1 minute exposures, stacked them with darks, flats and flat darks in PixInSight. Created two images, one aligned on the comet and the second aligned on the stars. This separated the star field from the comet. I processed the two images separately and then combined them using pixel math in PI. I used the ZWO ASIair for camera control and image capture.
