Caldwell 11 - The Bubble Nebula

Caldwell 11 is also known as NCG 7635 and is approximately 7,100 light years away. This shot was taken on September 25, 2013 with my monofied Nikon d90. The N11GPS with the Hyperstar was used along with an Ha narrowband filter. The subs were 30 seconds long.


Caldwell 11 is located very near the Messier 52 cluster as this wide-field shot demonstrates. This shot was also taken on July 22, 2011 with my modified Canon 1000XS using my 102mm APO refractor unguided on the CGEM mount.
