Extra Lightweight & Sturdy tube rings co-produced by RP-Astro (Italy) and Kasai. Hollow structure with hard aluminum alloy plates yields about 1/2 weight yet much more sturdy than normal metal tube rings. The box-shaped structure is especially strong against twists, far less bendings than normal one-plate metal tube rings. While reducing the total load to the mounting, more sturdy and stable holding is possible - ideal for astrophoto telescopes. Made-in-Italy stylish and minute finish is quite attractive. M6 x 3 reinforced female threads on top and bottom. Losmandy-compatible or Vixen-compatible dovetailed plate can be attached on either side. I.D. 303mm fits C11 and GSO 10" Newtonians. I.D. 358mm fits GSO 12" Newtonians and 12" Ritchey-Chretien. 1pc only is also available for the use of an accessory holder or else. Various sets as coming with Vixen-compatible dovetailed plate (L=335mm / M6 bolts x 2) and Losmandy-compatible dovetailed plate (L=357mm / M6 bolts x 4) are available, too.
