Explore Scientific Adapter for FFFR507X-00 to 2.5" Hex Focuser

This Explore Scientific adapter lets you use the FFFR507X-00 3-inch 0.7x corrector on a 2.5-inch Hex focuser, the focuser that comes stock on Explore Scientific's 127mm APO telescopes. Explore Scientific names it, item 510366, as the part that connects the corrector to that focuser.

• Threads the corrector onto a 2.5-inch Hex focuser.
