Product Info

Manufacturer Description

Rings will fit tubes with an outer diameter of 2.90" - 2.95" (Approx. 74 - 75mm).

These tube rings are high quality, cast-aluminum mounting rings that can be used for mounting telescope tubes on various mounts or on guidescope rails. All rings are hinged, felt-lined and have clamp-style rings for easy mounting or repositioning of the optical tube. Most rings have clamping knobs while a couple of size have clamping clips instead. Please see the photo for this product to determine whether it has a clamping knob or clip.

The base of the rings has a metric 6mm mounting thread. Gunmetal dark gray finish. If the outer diameter (OD) of the telescope is a little smaller than the inner diameter (ID) of the rings, you can shim the inside of rings with extra felt (not included).

      5.0 A Perfect Fit for that Classic 76mm Refractor

      Pros:

      Cons:

      Comments:

      During many an observing session, I typically like to use a variety of telescopic instruments depending on what's up in the night sky. Generally it would be one of my newer scopes along with my classic 76/1200mm Sears 6344 refractor.This meant that I would lug out two EQ mounts to use the scopes.

      So, I purchased a set of these 2.9" (76mm) rings to allow me to attach a Vixen dovetail bar to the classic instrument, thereby eliminating the need for two EQ mounts. It is just a matter of interchanging the telescopes on the newer EQ mount's head. Makes for a more productive and satisfying observing session!

      5.0 Nice rings, easily adapded to fit my tube.

      Pros:

      Cons:

      Comments:

      My scope tube is quite a bit smaller than these scope rings. These were the closest match I could find. The rings were well made and by adding a bit of self-adhesive craft foam and felted tape on top of that, fit my scope perfectly. Works great, very pleased. Prompt shipping too!

      5.0 Works perfectly

      Pros:

      Cons:

      Comments:

      I bought these to convert my dad's Meade Infinity 70 to an equatorial mount. I was pleased with how well constructed they were. Very solid. The camera mount screw/bolt itself was threaded into the ring so tightly I couldn't remove it by hand, but that's not a big deal. the interior was felt lined to prevent scuffs, but it was slightly too large a diameter to fit the older Meade 70az tube I test fit it on so I had to replace it with some thicker felt. After that it fit fine. I'm very pleased with it, and you can't beat the price.

      4.0 Simple and effective

      Pros:

      Strong Construction,Easy to Use,Lightweight

      Cons:

      Comments:

      The rings work perfectly on a 66 mm telescope aperture. They are easy to adjust and prevent the telescope to move undesirably. Have holes to suit a dovetail on both ends. The interior is lined with black felt to not damage the telescope and closing is by a well-built metal clamps. For the price are good rings for telescope.
