It is located close to M10. Identical to M10 but appeared a bit larger and slightly oval with the same brightness as its neighbour.

Nice globular like its neighbour (M10) although smaller.Easily resolved with a 8.8mm UWA eyepiece(104x).The cluster gave me the impression of having an iregular shape.

Very similar in appearance to M10. I swung the telescope back and forth, examining them at 49x, and eventually decided that M12 was a hint sparser, with more bright members resolved in front of the background glow.

An easy, lumpy glow at 49x. At 122x, a sprinkling of brighter members were resolved, with a medium-bright glow behind it.

I recall seeing M12 from my suburban (and more light polluted) backyard while doing the Messier list, but here at Alpha Ridge where the skies are noticeably darker I find that it is far more beautiful than I remember. It is a bit fainter than M10 but obvious when it slips into view at 28x. Even at this low magnification I can see that this is not your normal globular; it is loose in nature, uncertain whether it wants to fall into the Globular Cluster or dense Open Cluster camp. The field here is also a plus with many background stars. With the nice field and looseness of the globular it certainly brings M71 to mind, one of my all-time favorite globulars setamid rich Sagitta. The field stars boldly come right up to the object with maybe even one or two mingling as foreground points of light on the globular's periphery. The view at 75x is to beenjoyed as it accents the resolution better and still keeps a lively field. M12 seems to have a misty glow maybe about 5-7 arc-minutes wide, and there certainly does seem to be less of the mandatory symmetry characteristic of globulars. The 9.7mm gives a nice view but again tends to wash out this particular deep sky object.
