      Description

      Hello friends,

      so this time no ultra deep nor ultra thin field. We haven't had much telescope time lately due to research on the T1000.

      Just this NGC 2841 caught by Serge Brunier in only 3h of RGB (3x1h) with the QHY 600M at the F/3.2 focus of Omicron. The seeing was medium to poor (2").

      This kind of image requires more processing time than exposure to properly exploit fairly noisy data and generate a correct L from the RGB. But I find that in the end it goes very well in only 3 hours of RGB. It's crazy what this telescope brings, I am still surprised!

      Hope you will enjoy it.
