It is also possible to borrow NOAO's 5.75-inch Mosaic filters. It requires asking for permission (and hoping no NOAO users want them) and NOAO staff and Bill Wood making the exchange. You must fill out a “how will I replace these if they get ruined” form from NOAO.

We DO have 5.75 inch holders (made for the Windhorst set).
