12. Observations with the Faulkes Telescopes
... The comet 169P was first observed by the Near-Earth Asteroid Tracking system. In order to observe this comet we had to figure out if it was possible to view it from Faulkes Telescope South, a 2m reflecting telescope which is used for research as well as for use by school students around the world over the internet. ... Since 169P is such a bright object, we were able to use a red filter on some of our observations to provide a clearer image. ...
