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. |
