M3 Globular cluster

Finally there was a nice weather and no Moon. Summer nights are short; therefore it’s not optimal for deep space objects, which require very long integration time. Therefore I pointed my telescope this evening to globular cluster M3.

This cluster is located in constellation Canes Venatici and it’s one of the largest known clusters, because it contains around 500 000 stars.
