Widefield Cassiopeia

A widefield image of the constellation of Cassieopeia. Included in this image is the Double Cluster, M52, The Pacman Nebula and the Heart Nebula. I hadn't realised the Heart and Soul Nebulas were going to be in shot, of I'd have framed the image differently to include all of the Soul.

 

36 x 5 Minute exposures, Canon 450d, EF 50mm f/1.4 @ f/3.5, ISO400, mounted on an Astrotrac.

 

My camera has not been modded so I'm really pleased by how much red emissions I've been able to pull out.
