I bought these recently but my dob plans have changed.
Never used, in original packaging. Includes two bbirch CNC routed
rings ... 14-3/4" ID, 1-1/8" wide, and 3/4" thick.
Also includes the wooden struts and wooden pegs for assembling. Pieces came pre-drilled, from Astrosystems.
All you need to do is add a focuser board and glue it together.
Quality CNC routed ... very clean and nice!
