Nightlog 2011-05-11

- Beautiful and productive night, with several very nice Fabry-Perot
targets and first succesful spectropolarimetry with T Pyx.

- RSS guidance mapping tests. Concern about salticam fold-mirror
stability: there is clear Rho-dependent flexure between salticam
and rss images, and also variation when putting fold-mirror in/our.
Nevertheless, guiding worked fine with several tracks, after star
was hunted down. Needs more work to map.

- Tim ran the all-sky camera - check out the video on the blog-site,
which features a cool surprise visitor caught on camera!
