The Bad Astronomer writes: "Rolf Olsen, an "amateur" astronomer in New Zealand, took an amazing photo of a disk of material around the star Beta Pictoris, the first time this has been seen outside of professional observatories. Incredibly, he snagged it with just a 25 cm (10") telescope! A comparison with an earlier pic from a much larger observatory indicates he nailed it, making this a milestone for amateur astronomy."
