NGC 281 Pacman Nebula (Géar90 Ra).jpg

Add to Cart Add to Lightbox Download
NGC 281, aka the Pacman Nebula, in Cassiopeia, near the bright star Schedir (or Shedar), at right, and below Achird at top.

Above and right of Achird is the small green planetary nebula Abell 2, while above and left of Achird is the small star cluster King 2. Below NGC 281 and Schedir is a small reflection nebula unmarked on any of the print and digital star atlases I have, including the very comprehensive Millenium Star Atlas and the Tri-Atlas. Some fainter reflection nebulosity lies to the left of NGC 281.

This is a stack of 10 x 8 minute exposures at ISO 1600 through an IDAS NB1 dual narrowband filter, blended with a stack of 12 x 4 minute exposures at ISO 800, all with the Canon Ra on the Starfield Optics Géar90 apo refractor with the 0.8x Adjustable Flattener/Reducer for f/4.8. On the Astro-Physics Mach1 mount, autoguided and dithered with the Lacerta MGEN3 autoguider. All aligned, stacked and blended in Adobe Photoshop. An application of the Photokemi Star Tools Nebula Filter action helped bring out the faint nebulosity.
