APF72 AstroPhysics 2.7" Focuser
Filter Holder

For attachment of an LPS filter to an AstroPhysics 2.7" focuser, such as that found on AstroPhysics refractors, the APF72 may be used. It holds a 72mm filter, which accomodates medium format photography without adding vignetting.
The filter holder threads directly onto an AstroPhysics 2.7" focuser ahead of camera or visual accessories and adds about 1 inch of length.

The APF72 is sold as a set with a 72mm LPS filter, or separately as a holder for any standard 72mm camera filter.
