LB 2
This is the first image of candidate planetary nebula LB 2 that was detected in 2019. It is in Coma Berenices.
The actual discovery of the nebula came about by sleuthing OIII sources on Stefan Ziegenbalg's recent OIII survey. From there, it became clear that the emitting source was the LB 2 star that is listed over at HASH.
They suspected there might be 'something' here, but their estimate (of its size) was very conservative indeed.
We won't know if this is a true PN or some PN mimic until more study is conducted.
