- gnatman 2y agoI was struggling to see the planetary nebula inside that blue circle before I realized that is the planetary nebula. cool!
- perihelions 2y agoSomewhere there's a large, bright nebula in the shape of a red arrow no astronomer's ever noticed.

- jcims 2y agoI still don’t understand how objects in space of that angular diameter are still being discovered. I would have to imagine lots of people have seen it, but just never chose to document or catalog it?
- perihelions 2y agoThis is an extremely long (18 hour) exposure in specialized narrowband spectral filters that have no usefulness for anything other than these particular targets.
- jcims 2y agoOh nice!!! I looked at a couple sky surveys in different, and it was nowhere to be found in their data, that’s so cool!
