Description

This is a rather rarely imaged nebula, not far from The North American Nebula. When it finally cleared on Sunday night I pointed my double Esprit rig on it. I had the ASI071 with a 0.79x 3" TS reducer sitting on the Esprit 150 to collect RGB and the ASI1600MM with a 3.5 nm Baader Ha filter sitting on the Esprit 100 (both on Mesu 200), I managed to collect 25 x 10 min with each scope before clouds moved in at midnight. So totally 8.3 hours of HaRGB. Ha added to the red channel (blend Lighten in PS) and also used as Lum.
