Available from Cloudbreak Optics when we last checked, in the last two days. Sold from the shop’s own store; the price there is the one that counts.

Description This is our most popular modular flattener designed for all Stellarvue telescopes that operate at a certain focal ratio. The lens inserts into the 2” focuser and uses a tapered insert tube to more accurately seat the flattener in the focuser. The spacing distance from the T-thread on the flattener is 55 - 56 mm, so it will work as-is with any DSLR camera that has a t-adapter. For other cameras including all ccd cameras, consult us. Usually, a thread extension is all that is needed. T
