Description

Mixed image with new equipment and old one.
For me a very difficult target.
Perfect to compare the performance of the new filters, mount and focuser.
Really an improvement from last year non published picture. https://www.astrobin.com/298085

Anyway, I don't try to solve the small inside, maybe at some point next year :D
