Description

The Pacman Nebula, also known as NGC 281, is ~9500 light years away in the constellation of Cassiopeia. NGC 281 is a bright emission nebula and part of an H II region.

This image  was captured, in a Queen Creek (Arizona) Bortle 7 backyard, using a Skywatcher Esprit 150ED telescope. The telescope is mounted on a 10Micron GM2000 HPS II mount. The camera is a ZWO ASI 2600MM Pro using an Antlia SII, OIII, and HA 3nm filters. It was captured over 4 nights (2022-11-04 to 2022-11-07). The images were stacked/processed in Pixinsight and fine-tuning done in Photoshop.
