On this page I collect my observations of the globular star cluster M 92 in the constellation Hercules.
The globular star cluster M 92 in the Hercules constellation is somewhat smaller (depending on the author, it is 7 'or 8' in size) than its more familiar "brethren" M 13. It is located above the Keystone asterism, the most prominent part of the constellation More difficult to find than M 13. I was able to clearly see the bright nucleus - M 92 appears somewhat more concentrated ta the center than M 13 - but not dissolve single stars.
Size: 7' / 8' (Stoyan/Karkoschka)
Distance: 25,000 light years (Stoyan)
Rating: *** (Stoyan)
M 92 is located above the Keystone asterism and a little more difficult to find than M 13. First find the Keystone asterism!
The sketch by Michael Vlasov (DeepSkyWatch.com) provides a rough impression of what I observed in Summer/Autumn 2016 (my impression was much fainter and smaller than the sketch):
