M13 - Astrophotography [First attempt]

Here is my first picutre of the Great globular Cluster in Hercule constellation taken last night.

 

The full moon was a bit disturbing and despite the polar alignement was not precisely made, I managed to get a result that I hoped worst !

 

This image is made of 20 frames of 15 seconds each at ISO 1600 with a Canon T3i.

 

The telescope used is a 200/800 reflector (without coma corrector ^^)
