  * Two H-alpha filters (courtesy Rob Kennicutt). 
    * For each filter there are two transmission curve -- one tested for a beam at normal incidence and the other one for a beam at ~10 degrees.
    * Note from Janice Lee in 2006: "My rough estimate is 3e-17 ergs/cm^2/s in an hour for a 5-sigma point source detection."

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).
