Description

This is a HaRGB image using an Atik 460ex for Ha and an ASI071 for the RGB. 30% Ha was blended into the luminosity channel. The Ha data is a 2-panel mosaic created by Astro Pixel Processor. Final processing was done with Startools and Gimp. The was the first image using a new Riccardi .75x reducer/flattener. It performs quite well over about 90 percent of the ASI071 frame when using an AT80EDT. 45x150s RGB, 36x300s Ha.
