Details:
I found a discussion of this planetary nebula in the deepskyforum.com archives. This planetary nebula is named Baade 1, also listed as PNG 171.3-25.8. From the discussion “It was first identified as a faint nebula on plates taken with the 40” Bergedorf reflector of the Hamburg observatory but it was only confirmed to be a planetary nebula in 1935 on plates taken with the 100” Hooker telescope on Mt. Wilson by Walter Baade. It is the only planetary nebula discovered by Baade in our galaxy; he did however discover a number of them in M31. Baade 1 is to be found about 5 degrees SW of the Pleiades. Optically its central star is very faint at about 17th magnitude.” It has an apparent visual magnitude around ~14 and a diameter of about 38 arc-seconds, and lies roughly 2,500 parsecs (about 8,000 light-years) from Earth.
Tech Specs: Meade 12” LX-90 SCT Telescope, Antares Focal Reducer, ZWO ASI2600MC camera running at -20F, 2h 42m using 60 second subs, Celestron CGX-L pier mounted, ZWO EAF and ASIAir Pro, processed in DSS/PixInsight/Tycho. Image Date: January 20, 2026. Location: The Dark Side Observatory (W59), Weatherly, PA, USA (Bortle Class 4).
