Description


edit: added vers. C (soft processing version)

edit D: fixed color balance, and i think better antinoise/details proportions

edit: E: No new shots on Helix, still the same shots of 2015, but i've broken my ankle/fibula so i've time to lost :\ this is a total reprocessing using my new personal workflow that can mitigate noise :) hope you like it, i'll put a tutorial on my web site soon!

in memory and dedicated to Mario Monaco, stargazer and great Italian astroimager, Savona area, which was one of my examples during my childhood and adolescence, and he was a frequent visitor of the Cugn Goria, this plateau on the italian western Alps, that is almost an open-air sky theater, and where he photographed, those photos that for me will remain the masterpieces in film. I'm sorry that you have not had time to meet him in person
