|M75: Globular Star Cluster (Sagittarius) RA: 20h 06.1m / DEC: -21° 55'.4|
Instrument: 10-inch Starfinder
This small globular cluster resides in far eastern Sagittarius just across the border from Capricornus. Magnitude 8.0 HD 190617 is visible just 17' to the north-northeast. 4.2 magnitude 62 Sagittari resides about 6 degrees south of M75. My sketch was made with the Meade Starfinder 10-inch equatorial Newtonian at 129X. 29 field stars are recorded in the drawing. M75 appears 4' across with a brighter core but no stars resolved. Its total visual magnitude is 8.6, making this a good object for small aperture. Pump up the magnification to eek out as much detail as possible.
