SKYWATCHER FLATTENER & REDUCER FOR 120ED refractor which allows for the correction

which allows for the correction of the classical polar alignment and conic errors as well as the most important flexure terms of the optical tube

0 ports of EAGLE supply 1 Ampere so you will only need one USB cable to power and control ESATTO

making it compatible with the Sky-Watcher and Saxon AZ-EQ6 mounts

Polar scope (Southern and Northern Hemisphere)

Precession changes the direction of the Earth’s rotation axis

SKYWATCHER FLATTENER & REDUCER FOR 120ED refractor which allows for the correctionThe SkyWatcher field flattener and reducer for the Evostar 120ED transform your telescope into a professional astrographer. Refractors are affected by field curvature no matter what brand or diameter. This is not an issue for visual observations as eyepieces can partially compensate this aberration. On the contrary, when a refractor is used for astrophotography, a curved field will limit the corrected image circle and the stars on the border of the
