Equipment:  RCOS 12.5" telescope & STL11K CCD camera
Notes: 
Globular clusters are among the oldest structures in our Milky Way galaxy.  There are approximately 150 of these clusters in our galaxy.  This collection of eight images represents about three months of  imaging  efforts.  Most of the images were captured by remote control via the internet.  I hope this gallery will show the viewer the wide diversity of structure in  globular clusters. 
M12 - Globular Cluster in Ophiuchus
Magnitude   6.1     Size - 16'
LRGB = 150/90/70/60
Look for the little PGC galaxy lurking in the picture
NGC6366 - Globular Cluster in Ophiuchus
Magnitude 9.5       Size - 9.5' 
LRGB = 120/10/10/10 minutes
M13 - Globular Cluster in Hercules
Magnitude 5.9       Size - 20'
LRGB =  180/40/40/40 minutes
I seem to shoot this one each year & hope I get a little better at it .....
M30 - Globular Cluster in Capricornus
Magnitude    6.9    Size - 12'
LRGB = 90/30/30/30 minutes
Never gets more than about 32 degress altitude
