Description

Crescent Nebula revisited three years later with better equipment, better skies and some more skills.

It's the first presented image after this long period, in part due the COVID in part because the long integration time that I wanted and how short are these summer nights.

It was eleven nights with two rigs resulting on 75 hours of integration time. My longest integration time so far.
