M13 : The Great Cluster in Hercules

M13 Globular Cluster

A deeper version of my first attempt at this wonderful globular cluster. Althought the noise is much better than my shorter 300D photograph last year it could still use more exposure time. Click on the image for a larger version (1440x1211, 576kb).

Information about this object can be found on the SEDS website
