On this page I collect my observations of the globular star cluster M
10 in
the constellation Ophiuchus.
Introduction
The globular star cluster M 10 is located in the constellation Ophiuchus/Serpent
Bearer not
far away from the globular star cluster M
12.
According to Stoyan, it is interesting to observe both clusters in
succession and compare them (they are about 3.25° apart). M
10 is a little larger than M 12.
Size: 8' (Stoyan)
Distance: 14,000 light years (Stoyan)
Rating: ** (Stoyan)
Map

Find/Identify
Find: M 10 lies, together with M 12, on an oblique line in
the lower third of the constellation Ophiuchus, which runs to the
right to the star Lambda Ophiuchus (see map below). Since
there are no characteristic stars in its vicinity, I searched for M 10 for
a long time.

Identify: Since M 10 is located in a sky region with few
stars, it is almost sufficient to find a globular star cluster there. But
only almost, because to the right of it, there is the globular cluster M
12. In binoculars you can even see both clusters together in the field of
view (they are about 3.25° apart). (Image Courtesy

My Own Observations
Observations Summer to Autumn 2016
- September 7, 2016 (Mühlhausen/Kraichgau:
Skymax-102 on GoTo Mount):
M 10 observed - just a faint glow...
Observations September/October 2019
- Sep 28, 2019 (Sumène, France: StarTravel
120/600 on AZ
Pronto Mount): M 10 und M 12 (24, 10, 7, 4 mm) searched
for a long time for them, because there are no guiding stars nearby; M
10 with 4 mm perhaps resolved in to stars.
