I really appreciated your article several years back; it actually started me on seeking out the M31 globs. I used the coordinates that you furnished to make up my own chart in SkyMap Pro. Using my Discovery 12.5". I was able to bag G76 (easiest), G119, G213, G219 (Mayall IV), G233, G272, and G280. With a UWAN 4 mm e.p., many of these exhibited tiny disks using AV. I recall one extremely clear and dark night in particular; I was going after G213, and noticed an object not on my user-generated star chart within the field. It had a distinctly non-stellar appearance. I marked the position on the chart, and wow! I stumbled onto G233!

I LOVE going after M31 globulars, and hope that I have time this Fall to increase my bag limit.




I'm really glad to hear that article got you started on hunting down globs in M31. I just went back and updated the original article with more recent observations, so there are now observations and data on 37 globular clusters and 10 clusters/associations.

As far as increasing that total -- check out the link in the article for "M31 Globular Catalog in Excel" (also available on this page). I included all globs with a V mag of 16.0 or brighter (75 objects), so there should be plenty of targets to keep anyone busy. The clusters close to the core are the real toughies against the bright background glow so you have to be careful when comparing magnitudes.
