On this page I collect my observations of the open star cluster M
50 in the constellation Monoceros/Unicorn.
Introduction
The constellation Monoceros/Unicorn is also one of the constellation
that were unknown to me.
It contains the open star cluster M 50, according to Stoyan,
a brilliant bright cluster, which I can confirm. Stoyan even writes of
a "jewel of the winter sky," which is wrongly often ignored.
Size: 20' (Stoyan)
Distance: 3,000 light years
Rating: ***
