Here we have a look at M13 - my second visit :).
Last time round I thought I did OK, being an 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.
