Subject: BS visitor's viewport is protected with lexan 

The four horizontal viewports of arms are protected
by 3/8" thick, 8.5" OD Lexan disk of MR10 Polycarbonate.

ITMX, ETMX, ITMY and ETMY ccd cameras are not focused now.

BS visitor's viewport glass is now covered with Lexan MR10

this Lexan cover is in vertical orientation so becomes lose when the black anodized cover is removed.
It needs to be held in place

while it's housing is taken off.
