So with a 10$ Empire Tru-Blue torpedo level and a mirror AH, good results achieved on sun sights using 3x, 7x, and oopen tube. The levels were reversed for readings on both axes. Set up and leveling took less than 5 minutes. The 3 sight run, including changing scopes took 1 minutes. I guess that work on my 20 second levels was excess. They look really cool though.
