Description

This is data I processed from the Liverpool Telescope (free to download from their site). It only covers the central parts of the galaxy and I could only find two "colours" to use in their data base, taken with sdss-g (blue to green) and sdss-r (green to red) filters. I worked on it as an RGB image in PS after I made an artificial green channel from a 50:50 mix of the sdss-g and sdss-r data. I found 15 useful subs for sdss-r but only 3 for sdss-g, so the blue data is a bit weak. Fortunately there were 38 useful subs from a clear filter that I could use for luminosity in PS, so the details are rather good. All subs are 100 s, so totally 56 x 100 s = 1.56 h.
