Messier 30

M30, or NGC7099, a globular cluster in the constellation Capricornus, is about 75 light-years across and about 26,000 light-years away.

This globular is a little larger than M75, as well as a little brighter. In a 8-inch scope at 122x, the stars begin to resolve. At one end, two little strings of stars seem to stick out like antennas or rabbit ears. At 188x, the cluster begins to take on a mottled appearance, with a few more edge stars becoming resolved. M30 is infamous as being the final object necessary to complete a springtime Messier Marathon.
