On this page I collect my observations of the open star cluster M
18 (NGC 6613) in
the constellation Sagittarius.
Introduction
The open star cluster M 18 is located in the constellation Sagittarius and
is, according to Stoyan, more or less a "sub par" star cluster.
For me, it was attractive that I was able to observe it with the telescope
together with M 17 in the field of view.
M 18 (NGC 6613)
Size: 8' (Stoyan)
Distance: 5,700 light years (Stoyan)
Rating: * (Stoyan)

nearby DSO; M 18 is directly above it, and both can be observed together
in a telescope. (Images Courtesy

My Own Observations
Observations September/October 2019
- Sep 18, 2019 (Sumène, France: StarTravel
120/600 on AZ
Pronto Mount): Saw the nebula M 17 with a
straight nebula-like glow at the center
(24, 10 mm), below the nebula there was
a small OS (M 18) (leaves from trees disturbed the observation
of both objects); both not identified initially; I found both again
on Sep 19 and identified them.
- Sep 19, 2019 (Sumène, France: PS
72/432 on AZ
Pronto Mount): Saw the nebula
and the small OC below it (24, 7, 4 mm) just like the day before;
identified them according to Stoyan as M 17 (Swan/Omega Nebula) and M
18.
