Caught M79 GC in Lepus (again) today

#1

Post by pakarinen »


Last time I saw M79 was several years ago with my ST120, I think. Tried finding it with my 72ED the other morning with no luck, but I was able to just barely pull it out of the schmutz today with my 102mm using averted vision.

Took me a moment to make sure I was really looking at it, but it was definitely there. More visible than M4 for me at home actually.
Anyway, not worth a full-blown report, but I'll count it as a win. :grin:

Well done Olen. While M79 is not always the easiest from a typical suburban area, I would agree it is still easier under such conditions than is M4. The thing with M4 is because it is so large in angular size for a globular, giving it a lower surface brightness than M79. Also M79 has a tighter structure, with more noticeable core concentration, which helps with its higher surface brightness. Admittedly in a dark location M4 is not difficult to pick up with the naked eye. But under the average conditions that many observers work under, M79 is easier to pick up from my experience.

Just for comparison (from Telescopius):

M79: mag=7.7, size=9.6', SBr=12.3, class=5
M4: mag=5.4, size=36', SBr=12.9, class=9

M79 was pretty low in the horizon as I recall but I caught in the 10" Dob pretty easily. I also caught it in 15x70 binos like 4 years ago. It was close to Neowise at the time I believe (comet). Tree branches were a bit of a problem.
