Pease 1 (2013)
One of the rare planetary nebulas found within a globular cluster. Wikipedia informs me that there are only four others discovered so far. Here is a great article which includes a human eye color approximation view, because people are always very interested in that. Personally, I don’t see what is interesting about that, because a lot of space objects are just pale green without any color variation to our eyes. I’m happy we have instruments to aid our vision of the cosmos.
I went with the filters which the nebula shined the most brightly in so that light from the cluster wouldn’t overpower the light from the nebula. Since planetary nebulas tend to glow rather brightly through a couple of narrowband filters, it’s possible to see the nebula much more clearly using them.
North is up.
