About this product

Model:  Skywatcher_FR_ED120
Part Number:  20234

Screws directly to the M56 thread on the Sky-Watcher 120ED telescope's focuser draw tube. 

This Sky-Watcher 0.85x focal reducer/flattener is optimised for the Sky-Watcher Evostar 120ED PRO refractor.

Effectively reduces the telescope’s focal length by a factor of 0.85x to enable imaging at f6.375

Also provides much improved field-edge correction.

Use in conjunction with a DSLR-M48 Ring Adapter.

Can also be used with other similarly specified refractor telescopes when combined with our Astro Essentials Adapter.

Sky-Watcher .85x Reducer/Flattener for ED120
11 November 2020  | 

Very impressive field flattener which threads securely onto the ED120 drawtube . The locking ring allows accurate positioning the field flattener . It allows imaging at f/6.375 . I have only imaged the moon so far , but the result was impressive with sharp detail , and no sign of any false colour . I am looking forward to doing a lot of deep sky astrophotography ( open clusters , globulars , bright emission nebulae and brighter galaxies) .......
