Astronomers, like burglars and jazz musicians, operate best at night.

My astronomy sketches. Hover mouse over image for the inverted look. For fainter objects, take a look at the black-on-white original, sometimes it reveals more details.

By constellation:



NGC 6539 (Globular cluster)
Right ascension: 18h 05m Declination: -7° 35'
Constellation: Ophiuchus
Date/time: 2009.06.18 22:30 UT
Equipment: 12" f/5 Newtonian
FoV: 22' Magnification and filter(s): 167x
Seeing: 7/10 Transparency: 4/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Perfectly symmetrical, sphere-like globular cluster. Cannot resolve it at all. It's a bit fainter than the nearby NGC 6517, yet it's fairly larger than that. It's located in a field that's very sparsely populated by stars, this makes finding and following it a real adventure.
