yep, its very impressive, but it was taken with an SX Trius H694 which is a very sensitive camera with a high QE. Other bit is that its got over 12 hours of data.
moreover, his processing speaks for itself cause a 1 hour sub from a light polluted site would normally look washed out with light pollution.
it can be removed effectively in ST and PI but is not trivial.
doesn't look like an LP filter was used for luminance but regardless, that's quite an image.
