Description

Here is another scary nebula in Cassiopeia. Collected the photons on Friday night before the north obsy wall got in the way and I moved the scopes to galaxies around midnight. Used my Esprit double rig on the Mesu 200. Esprit 150 with ASI071 caught the RGB (17 x 10 min at gain 200) and Esprit 100 with ASI1600MM caught the Ha (13 x 15 min at gain 139). Ha added to the red channel using blend mode Lighten in PS.
