About this product

Model:  Skywatcher_FR_ED80
Part Number:  20236

Screws directly to the M56 thread on the Sky-Watcher 80ED telescope's focuser draw tube. 

This Sky-Watcher 0.85x focal reducer/flattener is optimised for the Sky-Watcher Evostar 80ED PRO refractor.

Effectively reduces the telescope’s focal length by a factor of 0.85x to enable imaging at f6.37

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.

Requires 55mm of back focus.

Best match for SkyWatcher ED80 doublet
Thursday, 14 March 2019  | 

The flattener perfectly fits on my SkyWatcher ED80 doublet! The images are flat-flat! No stars comma, chromatic aberration or anything related to that.

At the moment I'm using it for imaging with a stock Canon EOS T3i/600D and I get the focus without any problem. However, wasn't able to find the focus with a ZWO ASI 120MM mono planetary camera, so I'm looking for some extenders. Correct spacing is critical.

I recommend you ask a few questions before you buy this - FLO support team is the best, as always!
