I posted a Ha image of M16 a few days back. I was also working on a set of LRGB data and I thought I would combine it with the Ha data and see what I could get. I have no idea what is the normal way of combining this data. I first processed the LRGB data into a single layer in PS. I then used the Ha data as luminousity and reduced the opacity a bit. It tends to mess with the colour a bit but I think it looks OK. The LRBG data comprises sixty 1 minute lum subs and twenty 2 minutes in each of RGB.
