Observing log for 02-13-2013

Clear skies, low humidity.  Snow has melted off the dome.
some clouds exist in the valley, but well below the mountain peak.

Play-by-play:
01:44 - 
Mirror collimation complete.  ~0.9" seeing
Acquiring first target standard G191B2B.

02:20 - 
Acquiring second target OSU_RV hotstar1
variable seeing between 0.7 and 1.5, but mostly good seeing.
we are obtaining a short img of each star as well as the requested 
image due to saturation of the 10s exposure.

02:50 - 
Aquiring OSU_RV hotstar2
seeing settling down to ~1"
changed the imaging to red only rather than dual so that 
there are no changes as the drum changes

03:20 - 
Aquiring OSU_ORLs HoII
seeing a bit bouncy from 1-1.5"

05:50 - 
Acquiring OSU_CHAOS ngc3938_f2
seeing still uncertain between 0.9 and 1.2"

08:15 - 
Acquiring ND_rose
seeing settled to ~0.8"
using blind offset

10:30 - 
Acquiring OSU_CHAOS ngc3627_f2
seeing at 0.6"
guiding system crashed. had to stop image 10min in. 
Stopped exposure at 10 min.
adjusted obs to take 5x20 min and 1 10 min.

reaquired image and applied same offset quickly checked
alignment.  Less than 3 pixel shift.  restarted program.

11:34 - 
guider died again
due to guider problems and delays we had to end the observations 
on the OSU_CHAOS program early due to the beginning of twilight.  
Only 1h40 were acquired on NGC3627_f2.  It still needs another 
20min exposure to finish out the 2hours requested. Also as a result,
two of the images are 10 minute exposures.

12:42 - 
acquiring standard star gd153
