Globular Clusters - Winter and Spring
NGC4147 in Coma Berenices
Magnitude 10.3 - Diameter 4.1' - class. VI
Lum: 22 Apr 2007 - C8 @ f/6.3 - SXV-H9
L = 32 min (poor and deteriorating transparancy)
A pretty unknown globular cluster located at the outskirts of the Virgo Cluster

NGC 5466 in Boötes (and C/2003 K4 (LINEAR))
Magnitude 9.2 - Size 9.0' - class. XII
28 Jul 2004, 21:30 UT - C8 at f/6.3 - SXV-H9
L = 17 x 60 sec
NGC 5466 is, like NGC 5053, one of the more pathetic globulars. So, to make it slightly more interesting I waited until comet 2003 K4 passed along :-) Note the little galaxy, PGC 50187, to the right of the comet.

NGC 2419, The Intergalactic Wanderer in Lynx
Magnitude 10.4 - Size 6.2'
2003 Dec 17 - C8 @ f/6.3 - SXV-H9
L = 15 min binned 1x1
NGC 2419 is a very distant globular 300000 light years away. It got its nickname because it has long been suspected that it was not gravitationally bound to our galaxy, in fact it is. Despite the great distance it is comparably easy to observe as it is one of the intrinsically brightest globular clusters of our Milky Way. Two 7th magnitude stars to the west of the cluster make it easy to locate the cluster. One of those stars is visible here. This is the only readily available winter globular from my location. M79 south of Orion is too low.

NGC5053 in Coma Berenices
Magnitude 9.0 - Diameter 10.0' - class. XI
13 Apr 2001 - C8 at f/6.3 - MX516
L = 12.5 minutes (25 x 30 sec)
This sparse globular is located just one degree from M53. It looks more like an open cluster to me.
