Messier 15 (M 15)

On this page I collect my observations of the globular star cluster M 15 in the constellation Pegasus.

 

Introduction

M 15 (NGC 7078) is a globular star cluster that is located in the constellation Pegasus. Together with M 13, M 5, and M 3, it is counted among the "fantastic four" of the globular clusters in the northern hemisphere (Stoyan). Supposedly, it is the best globular cluster in autumn.

Size: 6' (Stoyan), 10' (Karkoschka)
Distance: 31,000 light years (Stoyan)
Rating: **** (Stoyan).

Find/Identify

Find: The globular cluster M 15 in the constellation Pegasus is located at the right edge of the constellation. If you extend the connecting line between the stars Baham and Enif for about another half, you will find M 15 (the globular star cluster M 2 in the constellation Aquarius is not too far away...):

Identify: If the globular cluster M 15 in the constellation Pegasus was found in the way as described above, it is also identified, because other globular clusters lie somewhat further away. (Image Courtesy of SkySafari Astronomy, www.simulationcurriculum.com)
