M13 - The Great Cluster in Hercules

Apologies all, traveling, work and life been getting in the way of imaging :) Back on the case now though!!

Here we have a look at M13 - my second visit :).

Last time round I thought I did OK, being a cluster often imaged it is hard work trying to find something extra, so I stopped looking and just processed it the best I could!

Unlike my previous version, I was very pleased with the structural detail showing in the core, the propeller is clearly visible along with a number of other structures and dark channels I had previously not seen.

Hope you enjoy.
