A planetary nebula with a diameter of 1 ly and about 200 ly away (Wiki says 2800 but parallax says 15.7mas ~200ly). Another William Herschel discovery. You can see the central star is still quite bright but is now a cooler white dwarf. There’s a nice double star system just top right of the nebula, although I suspect from their parallaxes (2.13 mas and 1.97 mas) it’s not a binary system. The nebula is much closer with a parallax of 15.7 so not associated with the double star.
