| For programs with bright IR stars, skip align beacon, but do the M7 and labao focus alignments. Then lock the star on the blue boxes and use the STST to fine tune any misalignment of the beacon flat. Check the beacon focus on the twfs occasionally to make sure it stays near zero, every 2-3 stars. | For programs with bright IR stars, skip align beacon, but do the M7 and labao focus alignments.
