Thanks for using the thicker felt. The rings fit my old Odyssey 8″ f/4 newtonian perfectly. This breathes new like into it on a motorized mount. The rings are surprisingly light and plenty stiff to handle this thick glass instrument. Great product!

I loved these. Fast, efficient customer service and fast replies and a great product. Exactly as advertised.

These rings are superb! I feel substantially more comfortable that my SCT is securely mounted and stable.

Wonderful alternative to traditional alloy rings. Perfect fit, clean 3D printing, and great value!

Saw a post on Cloudynights, had heard of Rouz Astro but never ordered so I reached out and asked what they would recommend for dovetails. Order was shipped within a few days with the 11inch metal plates. The rings are finely crafted and it fits really nicely around the tube! I’ll need another set for my refractor too.
