Description
Good used condition with clean optics
Screws directly to the M56 thread on the Skywatcher 120ED telescope's focuser draw tube.
This Skywatcher 0.85x focal reducer/flattener is optimised for the Skywatcher Evostar 100ED PRO refractor.
Effectively reduces the telescope’s focal length by a factor of 0.85x to enable imaging at f7.65
Also provides much improved field-edge correction.
Use in conjunction with a Skywatcher DSLR-M48 Ring Adapter.
Can also be used with other similarly specified refractor telescopes when combined with our FLO Adapter.
