Instrument: 17" f/15 equatorial classical Cassegrain
Magnification: 202x, 259x, 381x
Filter(s): None
Object(s): M62 (NGC 6266)
Category: Globular cluster.
Class: 4
Constellation: Ophiuchus
Data: mag 6.6 size 14.1'
Position: RA 17:01.2 DEC -30:07
Description:
M62 is a large and bright globular cluster. It has a strong central
stellar concentration, is approximately 45 light years in size, and
lies some 22,500 light years distant.
At 202x this globular was a somewhat resolved, highly concentrated
oval. A bright concentration was noted with the 5" f/5 finder at 37x.
Upping the power to 259x with the 17" caused M62 to be fully
resolved. Increasing the magnification further to 381x proved
counterproductive.
