Build your own laser spectrograph

The news is awash about a 17 year old girl who won a $100,000 scholarship for her spectrograph, but nobody actually linked to information about the thing. After some digging around, I located [Mary]‘s web site. It’s a work in progress, but I found an early version of her spectrograph build. The picture shows her project with a spectrograph head made for a meade telescope. Hopefully she’ll get documentation of her spectrograph head up soon. This is one of the better uses I’ve seen for a 5mw green laser.

I forgot to mention her sweet dobsonian telescope build. Very nice work.
