Description

M7

One can argue that integrating more than 17 hours on a cluster it's simply crazy!
But I really wanted, since quite many years, to get an excellent signal on Messier 7 from my polluted site to be able to drizzle and deconvolve it as much as possible, aiming to improve the native resolution of my optics.

This year I had this chance since both I could not go around my dark sites catching some fainter objects and the weather has been quite good during the last 40 days.
