ESATTO 3.5" LP ADAPTER FOR SCT WITH 2" THREAD

This adapter allows you to directly thread the ESATTO 3.5" LP onto the back of Schmidt-Cassegrain telescopes such as the Celestron 8" & 9.25" SCT and EdgeHD 800 which have a 2" SC thread. The ESATTO is the perfect solution for achieving precise focus and avoiding mirror flop and focus shift by leaving the mirror locked, if possible. Optical thickness is just 10mm.
