The levels arrived earlier this week. They were placed flat 90° apart on a first surface mirror (1/8") thick. The fs mirror was placed on a 1/2" thick piece or Corian. My AH has 3 screws for adjustment to level.
The results star sight LOPs were typically 10 to 15 to 20 nm from my actual position. I then removed the vials from their aluminum holders and placed them directly on the mirror. Same results.
But- for an unknown reason when a sun sight was taken, the 4 LOPs were perfect. They were right on top of each other and passed directly through my position.
The levels probably need some work or calibration to figure out where "level" is on them because certainly the bubble in the middle of the vial does not indicate level.
