On this page I collect my observations of the globular star cluster M 10 in the constellation Ophiuchus.
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)

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).
