Messier 16 (M 16) - IC 4703

Introduction | Map | Sketch | My Own Observations | References

On this page I collect my observations of the open star cluster M 16, located in the galactic nebula IC 4703, in the constellation Serpens/Serpent (Serpens Cauda/Head of the Serpent).

 

Introduction

According to Stoyan, M 16 (NGC 6611) is considered as the most beautiful open star cluster in the constellation Serpens/Serpent (Serpens Cauda/Tail of the Serpent). Usually, however, it is simply called the "Eagle Nebula" after the galactic nebula IC 4703, the Eagle Nebula, in which it is embedded. But actually these are two different objects.

Size: 10' / 45' x 20' (Stoyan)
Distance: 5.700 / 5.700 light years (Stoyan)
Rating: *** / * (Stoyan)

My Own Observations

Observations Summer to Autumn 2016

On September 7, 2016, I observed M 16 with my Skymax-102 on my GoTo mount in Mühlhausen / Kraichgau. It appeared to me as a very wide-spread open star cluster. I did not see the nebula IC 4703, the Eagle Nebula, in which M 16 is embedded.
