This adapter allows you to directly thread the ESATTO 2" onto the back of Schmidt-Cassegrain telescopes such as the Celestron 8" & 9.25" SCT and EdgeHD 800. The ESATTO is the perfect solution for achieving precise focus and avoiding mirror flop and focus shift by leaving the mirror locked, if possible.
The adapter fits into the body of the ESATTO 2" and so doesn't add any optical length.
From the back of the ESATTO you can connect accessories such as focal reducers for Schmidt-Cassegrain telescopes by using the SC thread adapter PL3600225, or cameras and accessories with 2" adapter by using the 2" visual back PL8410001.
