Description

I've previously posted an M51 combining this data with ODK14 data but here I've gone back to the drawing board and used only TEC140/Atik460 HaLRGB data and a slightly different approach to processing. DBE and SCNR Green in Pixinsight, the rest in Photoshop CS3. Mount was, as ever, a Mesu 200. I continue to be delighted by what can be achieved with such small aperture.
