CTA 1 (SNR G119.5+10.2) is a large and faint shell type supernova remnant in Cepheus, about 4,600 light years away, spanning roughly 1.8 degrees. It is the expanding debris of a massive star that exploded around 10,000 years ago. At its center lies PSR J0007+7303, a young rotation powered pulsar bright in gamma rays but faint in radio. The pulsar drives a pulsar wind nebula (PWN), a bubble of energetic particles and magnetic fields that are glowing in X-rays and gamma rays. The PWN shapes the interior of the SNR whereas the death of the star which created the shockwave formed the outer shell.
Nearby is NGC 40, the Bow-Tie or Scarab Nebula, an extremely bright planetary nebula about 3,000 light years away. It is unrelated to CTA 1 but adds a beautiful touch to the scene
I’ve worked on this project for nearly two months, I may collect more data later, because it does need it. The signal was really faint and it took a lot of patience. but I’m calling it done for now.
