This symbiotic star system has unique nebular features cataloged as
Ced 211
(Cederblad, 1947 in VizieR:
VII/231/catalog
) and is still actively referred to by that identifier in Wikipedia and Astrobin in various images. Cederblad listed angular dimensions of 1.5 arc minutes major and minor diameter.
Annotating this object visually using Cederblad's coordinates (converted via VizieR to J2000) and dimensions produces a slightly off-center circle that's too small. Cederblad was working with photographs in the 1940s. Now we can more accurately measure the size and location. The coordinates here in SIMBAD are accurate and precise. They match the coordinates in HASH PN Database 4.6 (2026) for this object, aka
PNG 066.5-70.3
with angular dimensions of 126 arc seconds (2.1 arc minutes). HASH pulls common names from SIMBAD, so it seems unaware of the Ced 211 historical alias as well:
HASH 4.6: PNG 066.5-70.3 aka R Aqr aka Ced 211 (http://202.189.117.101:8999/gpne/objectInfoPage.php?id=17686)
I think a secondary "otype" for this object should reflect its nebulosity and its historical identification as a "bright nebula" by Cederblad and as a planetary nebula cousin by HASH.
Examples annotating this object using the dimensions and coordinates from Vizier's Cederblad catalog vs HASH/SIMBAD coordinates and dimensions can be found in the comments to MJ Post's image on Astrobin: https://www.astrobin.com/1gjfsk/
