M 3

In the poorly known constellation of Canes Venatici there is a wonderful globular cluster, for many observers the finest in the northern skies only after M 13. It is Messier 3 (more data). A true breathtaking vision, when seen visually with a 30cm or bigger telescope, it was discovered by Charles Messier in 1764. It contains about 500.000 stars and it is one of the largest and brightest globular clusters known.

The image above is the average of 21 unfiltered frames, each integrated for 60 seconds with thePlaneWave 17 robotic unit part of the Virtual Telescope Project. The image has a scale of 0.7″/pixel.
