Telescope Tube Rings - Mounting Solutions - Carbon Fiber

Having setup dozens of imaging rigs over the years, one main point of concern is all the additional weight - specifically mounting accessories like dovetail plates, clamps, and tube rings.

At times, all these combined can weigh more than the telescope itself.

It is well known that additional weight is detrimental to mount performance and therefore image quality. I have been developing a number of solutions to address unnecessary weight, the largest savings come from the lightweight telescope tube rings. 

These are CAD designed and FDM printed for a combination of exceptional strength and low weight thanks to the tough carbon fiber composite material. 

Unlike traditional metal rings that are heavy, these are very light, typically less than half the weight and up to a quarter of cast rings.

Weight savings are excellent:
Rings typically weigh 250 to 500 grams depending on the size.

CNC aluminum (losmandy type)   bottom dovetail is 300mm long and 500 grams

Carbon top accessory dovetail (losmandy type) is 250 grams

But are they string enough?

Tested to take hundreds of pounds and a lot of abuse:
