Description:
Globular cluster very easily located, very bright, not very large,
with very briht core, but also it doesn't fade very fastly. At 40x
showed no evidence of individual stars, but it begins to reveal some
grainy texture. At 100x that is obvious. The field of view is filled
with many 12-13 magnitude stars, only somewhat brighter one is at the
field edge. Sketch is available at mentioned URL.
