returned to M10 (Halifax)

The globular cluster Messier 10 is another object I seem to only have one observation logged. I asked the Burke-Gaffney Observatory to aim into Ophiuchus and capture it.

Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, GIMP. North is up; east is left.

I like being able to see many of the individual members in the somewhat open core. When Chuck Messier logged it in 1764, it described it as "nebula without stars." Ah, no.
