V ZW 375 AKA Haro 6-29 AKA *GL Tau
Taurus
RA
04 37 23
DEC
+25 02 43
Type ?
MAG 15.3
You do not often see a object with a galaxy catalog ID (V ZW 375) and a planetary nebula ID (Haro 6-29), with also a star ID (*GL Tau). This got my interest when I saw this object with this unusual combinations of Id's So this is what I have found out. Fritz Zwicky started collecting blue looking compact galaxies in 1964 from the Poss 1 plates for his now famous Red Book,(CATALOGUE OF SELECTED COMPACT GALAXIES AND OF POST-ERUPTIVE GALAXIES ). He cataloged this object as V ZW 375 and his notes say "Very red Sc with compact nucleus".

So thats how it got the galaxy ID.
IN 1970 Sargent did a spectroscopic survey with the 200" Hale telescope on selected compact and peculiar galaxies from Zwicky's unpublished list of galaxies and found V ZW 375 to be a planetary nebula. NED note says that he sent Zwicky a private communication to inform him V ZW 375 was not a galaxy but a PN. As far back as 1953 Haro in Mexico noted in his paper (New emission stars in the dark regions of Taurus-Auriga-Orion) that Haro 6-29 had a Variable star with emission nebula. That is how it got its Planetary nebula ID.
In 1974 G Romano in Budapest did photometry on the central star In Haro 6-29 (*GL Tau) and found it to be variable from 15.7 to 17.5 photographic magnitude. so that is how it got its star name (*GL Tau).
To make matters more confusing MagaStar list this PN as Haro 3-29 and Simbad list it as Haro 6-29 Simbad did not recognize Haro 3-29. I did find a note in Simbad that says Haro 6-28= PN Haro 3-29, So that cleared that up.

I looked at this PN last week and here are a few of my notes " 375X small fairly faint central star AV only 488X with NPB filter got a good response to the filter looks a little brighter on the one side. Need to look again with better seeing at a higher power!"
Be sure to try this PN with all the different catalog designations when you get out and,
"GIVE IT A GO AND LET US KNOW"
GOOD LUCK AND GREAT VIEWING!
