+==== Findings with the tunable blue beacons during SPICA observing run in October 2022: ====
 <font 14px/Arial,Helvetica,sans-serif;;inherit;;inherit>At a setting of 10, the beacon is just visible on the labao at 100 fps. 13-14 gives better contrast., still without the star. Turning it to 13-17 after locking a star of mag V2.4 worked well to just suppress the starlight while not shining through to the TWFS. A star of mag V1.8 required settings from 20-30 and mag V4 required 13-16. Mag V5.2 was 11-14. I think these are at 40 fps on the labao. Mag V6 used settings of 10-13, about 2 clicks above where the starlight was seen. Mag V7.1 used the same 10-13.</font>
