On this page I collect my observations of the globular star cluster M 3 in the constellation Canes Venatici.
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)
M 3 is located in constellation Canes Venatici, but is easiest to find from Arcturus in constellation Bootes
