There was oil on the exit window of the Lyot filter and on the back face, I removed the Lyot filter and cleaned both windows and re-installed, am running Patrol now and I don't see any artifacts, it is partly cloudy so I'm not absolutely sure, also the filter is still coming up to operating temperature so the images are still off-band. I centered the Lyot filter in its mount and improved some insulation fitting and I added tape at the front of the instrument where stray light could get it around the pre-filter mount. I blocked spar travel with orange stairs and turned off MCC before disconnecting and removing the Lyot filter. That's the main pertinent information. I'm not sure if the Lyot filter will leak more oil, let's try it and see if anything changes over time. ___end___ Wed Apr 13 01:58:57 GMT 2011: PSPT Abort Patrol NOTE BY DARRYL: Wed Apr 13 02:22:04 GMT 2011 Adjusted the dome slot. ___end___ Wed Apr 13 02:43:45 GMT 2011 CHIP End Patrol Wed Apr 13 03:00:53 GMT 2011 MkIV 17_17.rawmk4 18_01.rawmk4 19_00.rawmk4 19_44.rawmk4 20_28.rawmk4 17_20.rawmk4 18_04.rawmk4 19_03.rawmk4 19_47.rawmk4 20_31.rawmk4 17_23.rawmk4 18_07.rawmk4 19_06.rawmk4 19_50.rawmk4 20_34.rawmk4 17_25.rawmk4 18_10.rawmk4 19_09.rawmk4 19_53.rawmk4 20_37.rawmk4 17_28.rawmk4 18_12.rawmk4 19_12.rawmk4 19_56.rawmk4 20_40.rawmk4 17_31.rawmk4 18_15.rawmk4 19_15.rawmk4 19_59.rawmk4 20_43.rawmk4 17_34.rawmk4 18_18.rawmk4 19_17.rawmk4 20_02.rawmk4 20_46.rawmk4 17_37.rawmk4 18_26.rawmk4 19_20.rawmk4 20_04.rawmk4 20_49.rawmk4 17_40.rawmk4 18_32.rawmk4 19_23.rawmk4 20_07.rawmk4 20_52.rawmk4 17_43.rawmk4 18_38.rawmk4 19_26.rawmk4 20_10.rawmk4 20_55.rawmk4 17_46.rawmk4 18_41.rawmk4 19_29.rawmk4 20_13.rawmk4 c18_22.rawmk4 17_49.rawmk4 18_44.rawmk4 19_32.rawmk4 20_16.rawmk4 c18_29.rawmk4 17_52.rawmk4 18_47.rawmk4 19_35.rawmk4 20_19.rawmk4 c18_35.rawmk4 17_55.rawmk4 18_50.rawmk4 19_38.rawmk4 20_22.rawmk4 17_58.rawmk4 18_56.rawmk4 19_41.rawmk4 20_25.rawmk4
