  7. This is supernova remnant CTB1/LBN 576 (Abell 85) in HOO+RGB. Known by some as the Popped Balloon or Garlic Nebula This has been a real challenge but I'm passed the stage of several targets a night and want to get the time in. I had never heard of this object until I was looking around Stellarium for more obscure targets. It's listed as a custom object. I spoke to a few imagers who had captured this and they told me how faint and difficult it was. It was hit or miss whether I'd pick up anything worthwhile with OSC but I wanted to give it a shot. These guys were hitting it with 30min exposures in mono. My 900s exposures showed barely any nebulosity. After searching on Astrobin, there weren't loads of images of it and I can't find a single image of this in solely OSC. A first? Maybe. CTB1 is approx 9780 light years away, spans approx 98 light years in diameter and is thought to be around 10,000 years old. It was catalogued by George Abell as a planetary nebula as Abell 85 but was suggested to be a SNR by Sidney van den Bergh in 1960. This was confirmed in 1971 by Willis and Dickel. A shell rupture can be seen in the top right of the image.
