• Most recent sky test results (24 Aug, 2007 UT)
  • Seeing was stable, 0.5-0.6" FWHM in V.
  • After careful collimation, star images were 1.9" FWHM in LLT Pulnix, using RG610 filter (2.9" FWHM with no filter).
  • Laser spot, observed with AO acquisition camera immediately after, was 2.5" FWHM, highly comatic (diamond ring appearance).
