We used the eyepiece from 1am-3:30am, and it was really cool! No echelle IOL for end of night because of long cals. Weather was great and seeing was down to 0.8". It was an easy and beautiful night. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 20:04 khigh 235( 1443) 93 59 16.2 18.2 17.6 18.7 16.6 -- 1.30 03:55 ecamera 295( 245) -50 65 13.4 13.9 14.6 13.6 14.0 clear 0.84 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 69 41 7 313 (NW) 1196 clear none 17:00 69 41 13 273 (W) 1029 clear none 18:00 68 40 3 259 (W) 1110 clear none 19:00 62 38 3 341 (NNW) 957 clear none 20:00 61 38 6 350 (N) 1023 clear none 21:00 62 38 7 358 (N) 1106 clear none 22:00 61 35 8 354 (N) 799 clear none 23:00 62 35 6 291 (WNW) 850 clear none 00:00 61 36 1 207 (SSW) 834 clear none 01:00 59 38 5 355 (N) 934 clear none 02:00 61 37 3 9 (N) 800 clear none 03:00 60 37 7 353 (N) 773 clear none 04:00 57 37 6 348 (NNW) 845 clear none 05:00 58 36 5 13 (NNE) 804 clear none Note: the wind was coming from the azimuth listed.
