 For the VIS dichroics, the WFS gets only 20% of the light, but 1 msec should still get to magnitude 5.0. For the VIS dichroics, the WFS gets only 20% of the light, but 1 msec should still get to magnitude 5.0.

 If the starlight is missing from the boxes on the TWFS on S2, you might be able to improve performance on by applying a threshold to ignore the TWFS boxes without flux This is likely caused by an alignment problem at the telescope/AOB, so notify charatech if you apply a threshold. Here are the steps to try this approach again on sky: If the starlight is missing from the boxes on the TWFS on S2, you might be able to improve performance on by applying a threshold to ignore the TWFS boxes without flux This is likely caused by an alignment problem at the telescope/AOB, so notify charatech if you apply a threshold.
