L990611000:31:43In the Proces of adjusting Rayleigh Convergence0
L990611001:05:33Nothing to gain from Conv tweeking2290
L990611001:07:25Changed the andgle of the daystar2330
L990611001:12:16Looks like it helped a bit, continuing3300
L990611001:15:06Helped again, continuing3610
L990611001:22:46Tightend Daystar in it's current position0
L990611001:41:27Tned dye from 589.156nm to 589.1573500
L990611001:46:55Sodium Convergence mirror adjusted3580
L990611001:50:01Clouds to the west0
L990611001:50:12Paused to change setup0
L990611101:51:47Resumed with setup 1, incremented.18391
L990611102:06:17Adjusted Halfwaveplates, They were on line18391
L990611102:07:12Ups!! Record 14 or 15 with to many counts in the sodium1
Forgot to change records per scan after the HWP adjustment
L990611102:10:00Rayleigh Convergence mirror adjusted18231
L990611102:27:05Thin clouds passingoverhead18271
L990611103:19:27Dye system tuned to getting better counts now at 589.16017151
L990611103:24:58Continuing to tune17151
L990611103:39:34The survailance radar works fine. A flock of geese in a V16761
formation triggered the radar!
L990611103:40:21The best setting on the dye is 589.161nm says the wavemeter1
