Hi all
Got my best ever Hydrogen Alpha pic of the Lagoon and Triffid Nebula region with Berts 300mm f2.8 flourite lens.
4x10 mins ISO 400, Idias uv/ir and Baader 7Nm Ha filters modded 350D. masking used to get detail
Earlier, Id taken a 3x5min ISO 400 colour image with the UHCS filter.
Ive replaced the red channel of that with the masked Ha image, then adjusted colour balance using Levels on the red channel till sky background is neutral. Its my first decent "Ha g b " image. Its not a true HA RGB as Ive completely replaced the original colour images red channel with the Ha one.
