Description

I observed this object on 23 September 2014 at the Okie-Tax Star Party using a 12” Skywatcher Dobsonian: Object was too dim to discern much detail. My impression is that it has a well concentrated core and a substantial halo. No stars resolved. 

I observed this object on 16 March 2016 at the General Nathan Twining Observatory (GNTO) in New Mexico using a 12” Skywatcher Dobsonian: Fairly large and well compressed. No individual stars discernible. Class V.

I obtained the calibrated lights frames used to create the final image from Telescope Live. The frames were imaged by the CHI-1-CMOS Telescope at the El Sauce Observatory in Chile.

Note 40,000 LY from Earth but 60,000 LY from the Milky Way core. Like Messier 54 (the other extragalactic globular on Messier's list), M79 is believed to not be native to the Milky Way galaxy at all, but instead to the putative Canis Major Dwarf Galaxy, which is currently experiencing a very close encounter with our galaxy. Being disrupted by the galactic tide, trailing a long tidal tail.

Shapley Sawyer Classification: V
Distance:  42,080 LY
Type: Far Halo Globular
Position w.r.t. core of galaxy: Below the disc and to the side of the Milky Way.
Any stars resolved: No
Undergoing Core Collapse: Yes
