Messier 16 (M 16) - IC 4703

Introduction | Map | Find/Identify | Sketch | My Best Own Photos | My Own Observations | References || Appendix: My Own Photos

On this page I collect my observations of the open star cluster M 16, located in the galactic nebula IC 4703 (Eagle Nebula), 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 "Eagle Nebula" after the galactic nebula IC 4703, the Eagle Nebula, in which it is embedded. But actually these are two different objects. Visually, I have only managed to see the star cluster so far, not the embedding nebula. With the eVscope, however, I was also able to see the nebula.

M 16 / IC 4703
Size: 10' / 45' x 20' (Stoyan)
Distance: 5.700 / 5.700 light years (Stoyan)
Rating: *** / * (Stoyan)

Find/Identify

Find: The open star cluster M 16 (Eagle Nebula) in the constellation Serpens Cauda is located at the upper end of a whole collection of DSO in the Milky Way region (see map above). The best way to find M 16 is to locate the lowermost star of the rhombus of the constellation Scutum (gamma Scuti, to the left of it is another star) and then to continue westwards for about 2.5°.

Identify: If the star cluster M 16 in the constellation Serpens Cauda was found in the way described above, it is also identified. (Image Courtesy of SkySafari Astronomy, www.simulationcurriculum.com)
