Your skill:5 yr
Date and UT of observation:09/06/00 23:00
Location & latitude:SW Wales UK 51 deg N
Limiting magnitude (visual):4.7
Seeing (1 to 5 - best to worst):3
Moon up (phase?):first quarter
Instrument:8 X 42 Opticron Imagic Binoculars
Description:The cluster appeared as a bright fuzzy star, using the Skymap
pro6 program I printed out a chart and made comparisons of brightness with
three nearby stars TYC 3098-870-1 mag 6.89,
TYC 3085-346-1 mag 7.23, TYC 3081-980-1 mag 6.75, the estimates were made
easy by defocusing the imgage until the stars diameter was close to that of
the clusters, the cluster was obviously brighter than the 7.23, just
brighter than the 6.89 and only very slightly brighter than the 6.75
which ties in nicely with the given mag of 6.5 for the cluster.
The limiting mag for the bino's was 8.7
