Product Details

  • All New Slot & Bolt Pattern

    The Radian Telescopes 14-Inch Universal D-Style Lightweight Dovetail Bar was completely redesigned to fit with any tube ring system. Unlike other brands, this dovetail bar uses mirrored angle slots to accommodate the width of the bolt pattern found on the most common tube rings. For the extra wide bolt patterns found on Astrophysics, TEC and Parallax rings, this dovetail bar has eighteen tapped 1/4-20 holes, 16 non-threaded counter-bored holes, and four 5/16-18 holes to bolt your hardware from the top of the plate downward.

    Thicker Shoulders for Less Flexure

    The Radian Telescopes 14-Inch Lightweight Universal D-Style Dovetail Bar is thicker than most mass-produced dovetail bars. It is machined from solid aluminum stock to have a 14.4 mm shoulder which will prevent any mechanical flexure. This extra thickness performs so well it can hold larger SCTs in set of tube rings.

    Balance Point Markings

    Balancing your telescope on your mount can be an annoying and time consuming process. The Radian Telescopes 14-Inch Lightweight Universal Dovetail Bar makes this easier with its incremental marking on each side. One side has markings in centimeters while the other has markings in half inch increments.

Radian Dovetail Bar Purchase

The dovetail bar came with both metric and standard attaching hardware which was thoughtful. I needed standard and the bar worked fine first try right out of the box. The delivery of products from OPT has been the most impressive thing to note in my entire experience with the company. I live in Georgia and when I build a project it always comes from both sides of the country, east coast and west. I ALWAYS get the shipment from OPT before any vendor on the east coast! This is awesome keep the hits coming OPT!

Radian 14 inch D-style Dovetail Mounting Plate

Very flexible mounting plate with numerous angled slots and threaded holes to attach most any equipment. Will be using inverted on top scope rings for guidescope and mini-PC. Good price and lighter weight than many competing products.

Fantastic Quality

The best dovetail I've ever owned. Very well made and tons of mounting holes for just about any scope. Mounted to my Explore Scientific 127mm triplet refractor easily. I also really enjoy the measurement markings on either side to make sure you get balance perfect. It has even worked as a ruler out in the field in a pinch once.

Looks Great - Did not Work for ME

Asked what would work with attaching to the top of my scope, was told this, but it does not (Dew shield gets in the way in the front, and not enough room to run it back more) - a shorter one would work a lot better for me. However, construction looks great.

Great dovetail!

Got two of them clamshelling my 80mm refractor. Very sturdy and easy to configure.

Top Quality

My former universal dovetail would not line up correctly and ended up being somewhat offset. The radian 14” had no trouble and I am convinced could attach perfectly to any setup. This is probably the best dovetail on the market today.
