High altitude cirrus scattered across the sky with with Cumulus and Altocumulus clouds scattered all around the mountains at various levels.

Sun is currently shining through mist and upper level clouds. ___end___ GENERAL COMMENT BY mcotter: Tue May 04 17:48:58 GMT 2021 Misty conditions persist so I am going to inspect the RA mechanical assembly, clean out any particulate matter that I had previously observed and measure the worm gear tension bracket and springs to verify that there is uniform pressure being applied between the worm gear and spur gear. ___end___ GENERAL COMMENT BY mcotter: Wed May 05 01:48:14 GMT 2021 Inspected the RA mechanism and discussed with Ben plans for a modification to part of the assembly so that we may gain better access to the clutch cam nuts. Additionally I cleaned the cam rollers and adjusted the gap that determines the amount of travel the worm assembly will move when it encounters undue resistance and the worm needs to to disengage from the spur gear. ___end___ UCoMP COMMENT BY mcotter: Wed May 05 01:53:45 GMT 2021 The occulter did not look like it was square, or parallel, with the field lens. I readjusted and squared all the components within the assembly and when tightening down the hardware I applied Loctite 242 thread locker to ensure that the screws maintained their desired tightness. ___end___ UCoMP COMMENT BY mcotter: Wed May 05 01:54:44 GMT 2021 Removed the ND filter from the front of the instrument and stowed it in its storage container. ___end___ GENERAL COMMENT BY mcotter: Wed May 05 01:55:25 GMT 2021 The weather was very poor today so no observing was done. ___end___ ONSITE STAFF: berkey
