Sky-Watcher Esprit 70EDX/Evostar 100EDX Flattener
Maximize the Performance of Your Sky-Watcher Telescope!
The Sky-Watcher flattener guarantees a flat field across a 44 mm image circle for your 70 mm Esprit EDX refractor or Evostar 100 EDX refractor. This means you’re at liberty to use some of today’s largest sensors with these Sky-Watcher telescopes, offering pristine detail from corner to corner! You can expect sharp stars across the entire field of view, turning these systems into high-performance astrographs.
This flattener also acts as a 0.92x reducer. It takes the 70 mm Esprit EDX refractor’s original focal length and focal ratio of 490 mm and f/7 down to 450 mm and f/6.4, respectively, and the Evostar 100 EDX refractor’s original 700 mm focal length and f/7 focal ratio to 644 mm and f/6.4, respectively.
