Supernova remnant CTA 1

By Rick Stevenson

A large but very dim target.
  70 hours of data.
 Thanks to Sakib Rasool for suggesting it as a target...
Maybe I did something to upset him and this was his revenge  ;-)
There's a bright planetary, NGC 40, at approximately 8 o'clock that's unrelated to the SNR.
