I measured the incursions of the reflected image on one of the images and it looks like the the decrease in tilt from 0.1250 to 0.0890 caused the image to move aproximately 110% further into the FOV. The simple minded solution is to try changing the tilt a bit more than the change made on Monday in the other direction from the original tilt, i.e. change the spacer height to more than 0.1610 inches if the rotating shutter's masher screw allows it. Stopping observations to work on making the change. ___end___ PSPT COMMENT: Wed Oct 6 21:27:14 GMT 2004 Resumed observations at 2115 UT. ___end___ **PSPT PROBLEM**: Wed Oct 6 21:27:47 GMT 2004 Calculated 110% change in opposite direction from original 0.1250 inch spacing to be 0.1642 in. Tried several combinations of washers and closest I could get to 0.1642 + was 0.1680 in. With this tilt, the masher screw on the rotating shutter brushes against the filter when rotated slowly by hand. The long screw was probably used because using a shorter set-screw would make access a bit challenging with the typical L-shaped allen wrench. I changed the screw for a shorter one that clears the filters when rotating. Access is made easier by moving a filter to the hatch position and removing the filter while accessing the screw with a plastic handled straight Allen driver (9/64). These have a longer reach. ___end___ **PSPT PROBLEM**: Wed Oct 6 21:57:47 GMT 2004 I just got email from Randy--they calculated a move to 0.1414. I will stop observations and make that change as soon as I have some lunch. ___end___ MKIV COMMENT: Wed Oct 6 22:02:25 GMT 2004 Centered O1. ___end___ **PSPT PROBLEM**: Wed Oct 6 22:11:01 GMT 2004 Running a flat-field with the CaK filter ND tilted with 0.1680 stack to document apparent over-tilt as an FYI while taking a lunch break. ___end___ MKIV COMMENT: Wed Oct 6 22:58:08 GMT 2004 Centered O1. ___end___ COMMENT: Wed Oct 6 23:00:51 GMT 2004 Spar ran into ladder.
