Description:
Djorgovski 1 or DJ1 is a recently discovered globular cluster. It was suprisingly 
large appearing over 6' across and is very faint. The clusters boundries are 
illdefined due to its low surface brightness and several 13th and 14th magnitude 
stars are scattered about the face. no central condensation was visible. This 
cluster is one of the more challenging objects for qwners of large telescopes.
A finder chart is a must, I used one printed from Megastar. Be warned though 
Megastar shows the cluster as being quite small.
Happy hunting and clear skies
