On this page I collect my observations of the globular star cluster M 5 in the constellation Serpens Caput/Head of the Serpent.

Introduction

The globular star cluster M 5 in the constellation Serpens Caput/Head of the Serpent is the brightest of its kind in the northern hemisphere, next to - or following - the globular star cluster M 13 in Hercules. In binoculars it appears, according to Stoyan, as a round nebula.

Size: 6'/12' (Stoyan/Karkoschka)
Distance: 25,000 light years (Stoyan)
Rating: **** (Stoyan)

Map

M 5 is located in constellation Serpens Caput/Head of the Serpent - some other globular star clusters are shown as well

My Own Observations

Observations May 2017

May 14, 15, 2017 (Mühlhausen: Explorer 150PDS on GoTo mount): M 5 only visible in the east later in the night; several globular star clusters seen well (7 mm; 24/16 mm on May 15), all somewhat "resolved", M 13 was the largest
May 16, 2017 (ditto): M 5 and further globular star clusters seen well as probably never before (24/4 mm), particular at that large size (4 mm)
May 20, 2017 (ditto): M 5 and further globular star clusters once more beautifully seen with 4 mm eyepiece

Observations June 2019

Jun 2, 2019 (Mühlhausen/Kraichgau: PS 72/432 on AZ Pronto mount; TS binoculars): M 5 observed, a glow that is brighter at the center; at higher magnifications still a glow... In binoculars not much fainter...
Jun 4, 2019 (Mühlhausen/Kraichgau: Skymax-127 on GoTo mount): M 5 observed, a glow that is brighter at the center; at higher magnifications still only a glow...
