Object(s): M53 (NGC 5024)
Category: Globular cluster.
Class: 
Constellation: Com
Data: mag 7.7  size 12'.6
Position: RA 13:12  DEC +18:10
Description:
Easily located near alpha Comae. At 49X a round nebulous glow with some mottling
but no stars resolved.
Increasing the magnification shows an unresolved background glow that is 
somewhat triangular in shape with a more diffuse halo around it. Moderately
resolved espescially around the edges with more stars appearing on the western
half than on the east. There is a very prominent star on the northeast edge
of the central condensation.
As with my 4".5 last year I was also unable to spot the globular NGC 5053
with my 8" but the sky conditions were far from ideal for this faint cluster.
There is a sketch on this object on my homepage: URL mentioned below.
