Messier 28

Observation Notes:

At 37X, this globular cluster is small, but still easily visible. I didn't see any granularity at this magnification. The nucleus was circular and tight, but not stellar. At 120X, granularity was still hard to come by. About 7 or 8 stars were blinking in and out across the surface. The fall off in brightness seemed softest to the NE.


At a distance of 18 to 19,000 light years, M28 has a diameter of 60 light years. It was the second globular cluster that was discovered to contain a millisecond pulsar--this pulsar spins around its axis once every 11 milliseconds. M28 was discovered by Charles Messier in 1764.
