Its profile fits both Vixen-style and Arca-Swiss clamps, and it carries UNC 1/4-20 and UNC 3/8-16 threads plus 6.5 mm through-slots for tube rings and accessories. This listing is the 185 mm length, which weighs 130 g.

Who It's For

This is a good match if you mount a telescope in tube rings and need a plate to join them to a Vixen or Arca-Swiss saddle, move a small scope or camera between a tripod head and a telescope mount, or want a second dovetail on top of your rings for a guide scope or finder.

• Double-sided: 6 mm grooves top and bottom, so the plate can be fitted either way up or used to carry accessories on top.
• Threaded holes: UNC 1/4-20 for cameras and accessories, UNC 3/8-16 for larger hardware.
• 55 mm slot (6.5 mm wide): lets you slide tube rings along the plate to balance the telescope.
