MKIII COMMENT: Wed Mar 9 21:54:19 GMT 1994 Tried pulling out south O1 guider photocell, (the micarta part only, not the lens assembly) to see if I could get rid of the N/S intensity gradient. Used 15 MAGNIFY, ILOOK for diagnostic. I didn't see any change. Reset to 80 MAGNIFY, QLOOK. Will try moving entire assembly nest time. DPMON COMMENT: Wed Mar 9 21:58:17 GMT 1994 No appreciable difference between Daystar temp of 5.0 and 5.1 Will leave temp set at 5.1. Test to continue tomorrow.
