Image Information

LBN 576 (also known as Abell 85 and CTB 1) is a faint supernova remnant lying almost 10,000 light years away. Coincidentally, it is also around 10,000 years old. Until recently it was thought to be a planetary nebula but recent studies confirm it to be a supernova remnant, the closest one known to Earth. Supernova remnants result from the explosion of a star in a supernova and are bounded by an expanding shock wave. They consist of ejected material expanding from that explosion.

I'm not sure why the huge difference in posted images versus mine except that maybe more RGB data would be beneficial. I have noted that most of the other images I have seen that show a good deal more nebula detail are taken with wide field refractors and thus likely to be a faster optic netting more detail in less time. For now the project will continue in RGB data collection.

This image is one of my longest yet. The luminance data is 83 - 15 minute frames (20-3/4 hours) and there are 68 RGB frames each 15 minute each (17 hours) with 6 hours red, 6 hours green, and 5 hours blue. Image processed in Pix Insight. Data acquired using ACP Scheduler and MaxIm 5.24.
