Features:

Useful for constructing special-purpose telescopes, bench set-ups, and other optical instruments.
Permits precise tip-tilt adjustment over a +/- 4 degree range.
Holder can be rotated 360-degrees.
Mirror is mounted using the metal shroud, or non-standard and oversized mirrors can be adhesively mounted.

A "vaneless spider" is useful as an adjustable mirror mount in folded refractors, shiefspieglers, and other reflective and catadioptric telescopes. You can also mount them to a curved Newtonian support of your own making. These are available with either a Newtonian-style holder (45° face), or a flat Cassegrain style holder. The body can be supplied with a flat portion to simplify mounting (please request this when you order). Made in U.S.A.
