Description

This really cool object was originally catalogued wrongly as a planetary nebula Abell 85 but it is in fact a supernova remnant. Estimated to have exploded about 10,000 years ago in the constellation Cassiopeia. It's shell is about 1000 light years across and the size of the full Moon from our POV. It is really faint and I captured data over 17 nights from late last summer. Over 35 hours of it.
Ha: OIII: R: G: B: 18.8:  10.9:  2: 2: 2: hours.
I like the weird lines lower right, looks like a number 5
