      Messier 78: a beautiful reflection nebula

      Messier 78 or M78, also known as NGC 2068, is a reflection nebula in the constellation Orion.

      M78 is the brightest diffuse reflection nebula of a group of nebulae that includes NGC 2064, NGC 2067 and NGC 2071.

      This group belongs to the Orion B molecular cloud complex and is about 1,350 light-years distant from Earth.

      This LRGB-image was captured with CHI-2 ( ASA500N telescope).

      Data from an older "Pro Dataset" - Nik Szymanek posted a great tutorial how to remove the satellite trails in this dataset.

      Total integration time: 120 minutes.

      LRGB 3 subs of 600s each, with the 4 filters.

      Processing with AstroPixelProcessor and Photoshop CC with .
