Description

CTA 1 (SNR G119.5+10.2), a 10,000 year old supernova remnant in the constellation Cassiopeia. The little planetary nebula on the left is NGC 40 and though it looks like its being surrounded by the much larger structure the 2 are at vastly different distances and completely unrelated.  This image marks my longest solo integration to date.
