Mounting a polarimeter!

John and I were up on the summit till about 1am, but we got the new polarimeter and a new dekkar (with calibration mounts) installed! Excellent. It took me an hour to realize that the cover had been put on the collimator - clear plexiglass that lets you get an "image" that looks horribly wrong and makes you think the system had been inflicted with a small child type knob-turner... At any rate, we're ready for the new calcite (~$10,000) to arrive so I can finish the calibrations. Sweet!
