Object: M52
Category: Open cluster
Constellation: Cas
Data: mag 6.9  size 13'
RA/DE: 23h24m  +61o35m
Description:
Directly in a line with orangeish alpha and white beta Cas,
and just 1 binocular field (4o) W of beta. M52 in binoculars
was a strikingly bright little object to direct vision, at
the S base of an "arrow-head" or compressed pyramid of mag
5 to 7 stars, whose N "arrow-point" was 4 Cas. The irregular
shape of the cluster was apparent, though several stars mags
8 and 9 were involved to SE, NW, ad amid M52 itself, making
observation of the shape of the haze somewhat difficult.
