It must cost a hell of a lot more than the $100k that the article mentions. That's just for the lenses.

The tracking mount all the glass is sitting on however is $15,000. (Paramount ME II by Software Bisque). Once you've spent 100k on glass what's another 15.

They probably had the tracking mount just lying around already, maybe from an older telescope. They are an Astronomy program, after all. And probably whipped up the camera holders in their machine shop (something else most physics departments have access to). What I wonder about is the "coated in a unique subwavelength nanomaterial"; did they really disassemble the lenses and apply an additional layer of coating, or are they referring to Canon's stock lens coating?

Just tossing out general cost for those interested in outfitting their backyard observatory with this rig. :) Having the access to resources they do is a big plus.

You raise a great question, disassembly>coating>reassembly. Now there's some time and cost.

Reminiscent of, and almost as cool as the SUPER WASP; Wide Angle Search for Planets

Yes, those are long discontinued EF 200mm f/1.8 L lenses :)

I guess when your talking about the entire galaxy, 200mm = "wide angle"
