M62




M62
Globular cluster
Constellation - Ophiuchus
Distance - 22Kly
Mag 6.4

Date 27/5/14
Transparency - Poor
SQM 21.39 (LM 6.3)

Telescope 16" f/4.5
EP - Leica ASPH x205

Sketch notes
This was the last observation of the night and some low cloud had drifted across making transparency poor and difficult to resolve the stars.
It did appear bright with a tightly packed core with a few outlying stars.
