Description

The Great Globular Cluster in Hercules.

_______________________

Yesturday's conditions where not ideal for imaging long exposures so I decided to go for this beautiful star cluster which could be done in one night.

I only managed to capture 59 minutes of RGB data with my C8 Edge HD & ZWO ASI1600mm.

------------

M13 is about 145 light years in diameter and contains about 300.000 stars with an estimated distance of 22 000 light years from Earth.

R: 11x1 min
