Messier 53 (M 53)

On this page I collect my observations of the globular star cluster M 53 (NGC 5024) in the constellation Coma Berenices.

Introduction

The globular star cluster M 53 in the constellation Coma Berenices shows, according to Stoyan, the typical appearance of mayn globular star clusters: a bright light ball with increasing brightness towards the center. Only in large telescopes, M 53 can be seen as a compact star cluster rich of stars. In the eVscope, a lot of stars can be resolved.

M 53 (NGC 5024)
Size: 4' / 7' / 12.6 (Stoyan/Karkoschka/Wikipedia)
Distance: 32,000 light years (Stoyan)
Rating: ** (Stoyan)

Find/Identify

Find/Identify: M 53 is located in constellation Coma Berenices, but is easiest to find from Arcturus in constellation Bootes (and thereby to identify):

My Own Observations

Observations May 2017

• May 9, 2017 (Mühlhausen/Kraichgau: Explorer 150PDS on GoTo mount): M 53 a faint glow that is brighter at the center; fainter than M 3 (therefore not found on May 5, 2017)
• May 10, 2017 (ditto): Ditto
• May 14, 2017 (ditto): M 53 a glow, but quite good to see, brighter core?
• May 15, 16, 20, 2017 (ditto): Observed M 53 in my final "observation series" of globular star clusters, glow, brighter core, quite good to see

Observations June 2019

• June 4, 2019 (Mühlhausen/Kraichgau: Skymax-127 on GoTo mount): M 53 a faint glow that is brighter at the center; smaller than M 3 and M 5

Observations March to August 2020

• March 18 (in the morning), 23, and 24, 2020 (Mühlhausen/Kraichgau: eVscope): M 53 photographed.
• April 21, 2020 (Mühlhausen/Kraichgau: eVscope): M 53 photographed.
• May 17, 2020 (Mühlhausen/Kraichgau: eVscope): M 53 photographed in the new rectangular format without overlay.
• May 21, 2020 (Erkerode: eVscope): M 53 photographed (r.f., n.o.).
• June 7, 2020 (Erkerode: eVscope): M 53 photographed (r.f., n.o.), sky not optimal (Unistellar weekly challenge).
• August 8, 2020 (Erkerode: eVscope): M 53 photographed (r.f., n.o.), eVscope out of focus

Observations June 2021

• June 10, 2021 (Mühlhausen/Kraichgau: eVscope): M 53 photographed (n.o., r.f.), new image size and processing.
