NGC 869 / NGC 884, the famed ”Double Cluster”, two open clusters in Perseus

Made another attempt at the Double Cluster with my new camera (Canon T5i). Here's how it compares to my previous attempt! The difference in resolution is noticeable, as some of the closer-together stars are now split instead of blobbed together.

double cluster NGC 869 / NGC 884
Canon T5i - December 27, 2013: Stack of 22 subs, 12 bias at 300mm, f/5.6, ISO 3200, 1.3 sec
Canon Rebel XT - April 14, 2013: 68 subs, 10 dark, 10 bias; subs at ISO 1600, f/5.6, 300mm, 1.3 sec
I continue to be impressed with this new camera! At only 22 subs, I still brought out more stars than I did with 68 frames before! I can't wait to try this target with my motor-driven EQ mount that is set up and ready to go - just waiting for clear skies!
