Supernova remnant CTA 1
« on: 2018 January 09 10:49:21 »
A large but very dim target. This one has been kicking my processing butt for a few months but I think I've finally made something of the 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. CTA 1 also contains the the first ever high magnetic field pulsar to be discovered through its gamma-ray pulsations, PSR J0007+7303, but sadly it didn't appear to be visible in this image.
