On this page I collect my observations of the globular star cluster M 3 in the constellation Canes Venatici.

 

Introduction

The globular star cluster M 3 in the constellation Canes Venatici belongs, according to Stoyan, to the brightest and most worth observing globular star clusters in Messier's catalogue.

Size: 7'/10' (Stoyan/Karkoschka)
Distance: 32,000 light years (Stoyan)
Rating: *** (Stoyan)

Find/Identify

Find: The globular star cluster M 2 M 3 is located in constellation Canes Venatici, but is easiest to find from Arcturus in constellation Bootes - it located on a line between Arcturus and Cor Caroli in Canes Venatici.

Identify: If the globular star cluster M 3 in the constellation Canes Venatici was found in the way described above, it is also identified.There are no larger globular star clusters nearby (M 53 is definitely smaller). (Image Courtesy of SkySafari Astronomy, www.simulationcurriculum.com)

The sketch by Michael Vlasov (DeepSkyWatch.com) provides a rough impression of what I observed (my impression was much fainter than the sketch): Messier 3 (Globular Cluster) - Sketch by Michael Vlasov (Copyright © Michael Vlasov 2016)
