On this page I collect my observations of the open star cluster M 11, called Wild Duck Cluster, in the constellation Scutum/Shield.

 

Introduction

The open star cluster M 11, called Wild Duck Cluster, is located in the constellation Scutum/Shield and, according to Stoyan, is regarded as the most beautiful of its kind that is visible from central Europe. M 11 is located in the Scutum cloud, a special section of the Milky Way.

Size: 7' (Stoyan)

Map

M 11 (top) belongs to the constellation Scutum/Shield. All other objects belong to the Sagittarius constellation (M 8, M 16, M 17, M 20, M 21, M 23, M 24). (Image Courtesy of SkySafari Astronomy, www.simulationcurriculum.com)

 

Find/Identify

Find: M 11 is located at the "tail end" of the constellation Aquila and close to the constellation Scutum. I see there a chain of stars, which comes down diagonally and ends horizontally to the right (at beta Scutum). Below you will find the star cluster M 11, which you can quickly recognize by its glow. To its right there is a small trapeze (see Identify). (Image Courtesy of SkySafari Astronomy, www.simulationcurriculum.com)

Here is another closer map (Image Courtesy of SkySafari Astronomy, www.simulationcurriculum.com):

Identify: M 11 in the constellation Scutum/Shield is located close to an irregular trapezium, which I can see well in binoculars (and depending on the telescope, it is on the left or right side of M 11), but cannot find on many star maps and in many astronomy programs, because it is quite small. This trapezium helps me to find the star cluster and also to identify it as M 11!
