This data was sitting around for a while until somebody on the PI forum asked about colourizing NB bi-colour data so I used it as an example.
Would have been nice to have better data (at the time we were having guiding issues and doing short NB subs) and also some RGB stars. Still, it's a cool object and interesting at long focal length.
