Here is a list of bright galaxies sorted by magnitude. Two pages give notes and the list.
My reference is: Third Reference Cat. of Bright Galaxies (RC3) (de Vaucouleurs+ 1991)

Thanks Glenc, you really are a legend. Your lists are fantastic, and I have several that I am working through, depending on what time it is, and which part of the sky is accessible. Thanks again.
Thanks Glen, that is a great list for my galaxy hunting and imaging.
Cheers

Glen,
This is an interesting and useful list of galaxies.
I have produced from this list a further sub-class PDF list, which has 163 galaxies south of -30 degree declination, which might prove of interest for the true parochial southern observers.
As a general comment, one of the first things I have noticed here that there are not bright galaxies south of -80 deg declination. I've review the data collection of the RC3, as I think much of this region was not surveyed. However, the NGC for example lists only five galaxies in this region, being; NGC 2144, NGC 2573, NGC 3149, NGC 6438 and NGC 7637. The IC has IC 2051, IC 4333, IC 4545, IC 4640, IC 4641 and IC 4647 - none with magnitudes - but again these have not been surveyed well.
In this region, NGC 6438 is the brightest at 11.6V (13.0B) magnitude- so you may be safe to put it in your given list of bright galaxies. This is one of the most wonderful examples of interacting galaxies in the whole sky but is neglected everywhere because it isn't popularly listed - even Hartung missed it! Its position is at 18h 22.3m -85 deg 24' in Octans, being 2.6x2.2 arcmin in size. (I've attached a small b/w image. Note the nearby double star
NGC 2573 : Nebula Polarissima 01h 41.7m -89 deg 03' is (13.8B) still has no reliable visual magnitude, though 13.5v is sometimes quoted.
As a general comment, I find far more useful than the PGC catalogue, which seems to have more reliable data and some objects 77,141 - and most of these are visible in largish amateur telescopes. The original PGC was updated to Paturel's great "Hyperleda I Catalogue" of Galaxies (2003), and contains 983 361 galaxies. The RC3 version listed here was prepared in view for the eventual availability of the then new Hipparcos satellite data - but does not contain the corrections added after the Hipparcos data was analysed. As far as I know, the Hyperleda I catalogue has not been adopted to many of the electronic star charts. As far as I know, this is currently available in the AstroPlanner software. though it is 162.2 Mb in size (21.6Mb compressed) - the fifth largest in the catalogue available for it.
[All of these, by the way, are available through the (CDS Centre de Données astronomiques de Strasbourg) VizieR service pages at;
http://vizier.u-strasbg.fr/viz-bin/VizieR. Readers here can type "PGC", and see all these catalogues and the older obsolete versions.]
As a comment, obtaining the morphological galaxy types for is probably of interest for some of the readers here. Believe me I search for many hours on the net without much luck, until I found out that it was unobtainable except if you bought the RC3 book itself. (Bugger!)
However, I eventually found all the various versions of the morphology types also in Vizier at http://cdsarc.u-strasbrg.fr/viz-bin/getCatFile?VII/155/mtypes.tex.
For my own use I made up a up PDF document to refer for my own use - but a few others might find it also useful. This I have also attached.
Anyway, thanks for the EXCEllent spreadsheet! :)
COMMENT: Is there any other way of uploading other PDF files greater than 150kB here? It to me ages to compress the documents to size! I haven't used any written documents this small since I was using Windows 3.1 during the almost pre-historic Donkey Kong Era! :lol: :lol: Surely files to 500kB or even 1Mb should be possible - or perhaps there should be a simple policy of dumping large files after one or two month - if space is a problem?

Zipped files can be up to 500kb.
Otherwise people can upload the documents to their own webspace and provide a link, or use the IIS FTP Service if it's something they think is worthwhile for others to need to download.

Thanks Nyx Aether and Mike for your input. The pdf file of galaxy types is handy. As you say the PGC provides a more complete list but does not give visual magnitudes. The PGC lists 6 galaxies south of dec -80 and brighter than Bmag 13. They are IC 2051, ESO 15- 8, NGC 6438, NGC 6438A (in your image), NGC 6920, and ESO 27- 1.

LIST OF OBJECTS WITHIN 2.5 DEG OF OTHER OBJECTS, SOUTH OF DEC+50.
Thanks for your list edosaurus_rex, its is an interesting way to observe.

Thanks Glenc!
If I had thought about it for 5 extra seconds I would have set up the list with the base objects in magnitude order. This way an observer could start with the brightie's at the front of the list then move around in the directions given for the near objects to find more while in the same neighborhood.
If life doesn't get too much in the way this weekend I'll reprogram to reorder the list that way.
