Product Info

Manufacturer Description

Rings will fit tubes with an outer diameter of 3.88" - 3.95" (98.7 - 100.4mm).

These Antares cradle 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 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). Price shown is for a set of 2 rings.

Antares cradle rings are available in over 10 sizes. However, if a size is not listed on our site, then we do not have it. Custom sizes are also not available.

      Pros:

      Cons:

      Comments:

      I have an old catadioptric telescope, but the original rings were missing. The Antares Cradle Rings are excellent, and they did the job well in securing my telescope. It was a good buy.

      3.0 Decent budget rings, a bit under 4"

      Pros:

      Cons:

      Comments:

      Decent quality budget rings, they were a little too small for my 102mm tube (would be perfect on 100mm tube). The great folks at Agena gave me a prompt refund when returned.

      5.0 Does The Job

      Pros:

      Good fit,Strong Construction,Easy to Use

      Cons:

      Comments:

      These rings fit my C102 f10 Celestron scope perfectly. They mounted easily on a Vixen dovetail bar. Working fine in the field. Plus, it's always a pleasure with Agena; service is excellent.

      5.0 Perfect for Nexstar 102/Skyview Pro

      Pros:

      Strong Construction,Easy to Use,Accurate

      Cons:

      Comments:

      I bought a Nexstar 102 OTA at a bargain price, but soon got tired of it being mounted side-saddle on my Skyview Pro mount. Since I had a spare dovetail, these rings fit the bill perfectly. Quality is very good, the chrome knobs are beautiful, and the finish matches the mount. Perfect!

      4.0 Antares 4" Rings

      Pros:

      Easy to Use,Strong Construction

      Cons:

      Comments:

      The rings fit my C102GT refractor perfectly. I did have to reglue one of the felt strips back down to the ring, no big thing. It makes balancing the refractor very easy.
