astroenthusiast 279 Posted July 21, 2021 The image of Messier 51 was captured using a ZWO ASI533 MC Pro color camera with an exposure time of 20 minutes, camera temperature at -30.4 Celsius. The telescope equipment used was an Explore Scientific ED 102 mm APO Airspace Triplet refractor at F/7, Sky-Watcher EQ6-R Pro Equatorial mount. The processing software used was Astro Pixel Processor & Adobe photoshop, unfortunately no calibrated frames were used or LPO filter. 1 Link to comment
