The Rosette Nebula (NGC 2237) with the beautiful open cluster NGC 2244 at its center. This is a stellar nursery about 5500 light years away in the constellation Monoceros. This image was shot from my driveway in Austin, Texas, the morining of 2021-03-15, under a Bortle 6-7 light dome. RedCat 51 f/4.9 250 mm telescope, Baader UV/Skyglow filter, and ZWO ASI533 MC Pro camera. Capture controlled by a ZSO ASAIR on a Sky-Watcher AZ EQ5 Pro mount with a ZWO mini guide scope and camera.
26 3 minute sub exposures for a total of 78 minutes total exposure at unity gain and -10C. Clouds, thin and thick, spoiled most of the 3 hours of exposures taken. Images stacked and processed in PixInsight, and Topaz DeNoise, with final crop and exposure in Photoshop.
The ASIAIR controlled Sky-Watcher mount makes it much easier for me to capture data under bright urban skies. As a result I already have a backlog of data to process!
