The 3.0″ and 3.5″ Feather Touch focusers need an end cap and the most popular end cap for the 3.0″ focuser is the M72 threaded end cap and the most popular end cap for the 3.5″ focuser is either the M72 or M92 thread end cap and these end caps are sold separately.
FC100 focuser has OD of 3.3″ so MPA-TAK2.5 is better fit than MPA-TAK2.7.
MPA-TAK2.7 pinion assembly is the most popular upgrade which fits all Tak 2.7″ stock focusers.
