Night Assistant:

Problems: 

Guider failure durning first u band exposure of the night. Failed durning a short "pointing" not during a science image.

Lost guider on exp 194103. No active CCDs. Increased guider time to 1800ms, failure precisted. Re-submitted image to the queue, found 3 guide stars.

Moved telescope to "bonus" target at end of night. Was not informed of galactic coordiantes of pointing ahead of time and over exposed, saturating a majority of objects.

Comments: 

Guider ran smoothly after inital problems.

Telescope pointing was again stable to within ~30 arcseconds in each of RA and DEC over a 4 hour script time.

Standard field finder script was very useful.
