Product Details

  • Parallax Instruments Standard Telescope Mounting Rings for 155 mm OD Tubes

    These 155 mm outside diameter split tube rings, specifically designed for the Takahashi FS-152 and TOA-130, are made of die-cast aluminum, finished in gloss black paint, and lined with felt. The hinges, no-tool knobs, and hardware are made of stainless steel for long life and easy telescope installation and removal. Parallax Instruments Telescope Mounting Rings Please note that the photograph shows a selection of the Parallax Rings while this product only includes the two rings of the size you order. The rings are installed onto your mount or mount dovetail plate via a 1/4"-20 thread mounting hole that is drilled and tapped in the flat boss on the bottom of each ring. A similar hole is drilled and tapped on the top boss so that accessories, such as a piggyback camera mount, can be attached.

    When you get to your shopping cart, please write what you are going to mount the rings to in the comments section. Most standard rings are in stock, however, certain mounting set-ups may require some custom drilling and thus shipping may take a little longer. Please call us at 1 (800) 483-6287 or email us with any questions. Thanks!

    Typical Parallax Quality

    I've owned 3 sets for various scopes, and as always, these are one of the best out there. Clamps solidly and firmly without any play or creep when the heavily loaded tube, camera, filterwheel, etc. are vertical (unlike some that I've owned that just never clamps tight enough). Only "complaint" is that mounting bolts aren't provided--but really is a non-issue for most of us.
