These OCAs were indispensable back when I had my Dobs. These threaded into the nose piece of my 1.25 inch binoveiwers and allowed me to reach focus with binoviewers on all of my Dobs - my 8 inch. my 12.5, my 18 and even my 22.5 monster Dob!

These sell for 199.00 each on Siebert optics website. I will sell my last one - 3x magnification- for 65.00 including shipping in the USA!

I accept paypal (pls add 3%) and Zelle Quick Pay.
