Description

CTA 1 is a very dim supernova remnant in Cepheus.

The bright object at about 8 o'clock is the unrelated planetary nebula NGC 40.

I had a look for PSR J0007+7303, the first ever high magnetic field pulsar to be discovered through its gamma-ray pulsations, but it didn't appear to be visible optically.
