Week two of WFU at HET

Last week we removed 47 of the 91 HET mirrors. See the very nice pictures posted by Coyne Gibson at

This week we expect to install the mirror protection net and then tarps over that net to protect the remaining mirrors in the array. After that we will start to paint the upper hex black to reduce the amount of scattered light from our future expanded pupil size.

Next week we should be removing the old PFIP.
