esb galaxies ?

I was touring some galaxies the other night when my argo navis
identified in (corvus maybe) one .. esb -801 ?.. something like that anyway.. It was quite large and bright .Anyone know much about how this classification came about ?..

Argo Navis have ESO data in miscellaneous galaxies ?
There all over the place.

Haven't the last few nights been great. Pity about the current cloud.
I love finding out info about unusual stuff.
These links might explain the what the ESB classification means.
News to me, I hadn't heard of it before!! Cheers, paul.

Thanks that must be it .. I had to pack up right away so didn't get to read the data.. I guess its a well known galaxy as it was very large .

Graham, this is about the 1982 ESO survey.
http://cdsarc.u-strasbg.fr/viz-bin/Cat?VII/34C

and this is the catalogue of 18,422 DSO south of declination -20 approx.

It reads ESO-444- G81.. now its clear of the trees and I can get a shot of all of it it looks like M83.. because it is .. the data on both lists mag 7.9

The NGC 2000 gives the mag as 7.9 but "THE SKY" gives 8.01.
The galaxy is on number of catalogues here are some.
M83
NGC5236
Dreyer description: Very remarkable! Very bright, very large, extended 55°, extremely abruptly brighter middle nucleus, 3-branched spiral; = M83.
Other ID: ESO444-81
Other ID: MCG-5-32-50
Other ID: UGCA366
Other ID: PGC48082
Magnitude: 8.1
And to think that the NGC was put together to combine all of the catalogues together

The V magnitude of M83 is 7.3 +- 0.3. (7.0 to 7.6). B mag is 7.91 +- 0.3, B-V is 0.66.
Lacaille found it with a 0.5" refractor so it has to be brighter than mag 8 IMO.

Ok thanks guys

.. my argo navis pulled this up out of a tour
Another few objects on M83 pops up ... wonder why ?
