SKYWATCHER FLATTENER & REDUCER FOR 120ED refractor With a 2 x Barlow

With a 2 x Barlow lens and a planetary camera you will get the right pixel scale for imaging planets and the craters of the moon

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

Polar scope (Southern and Northern Hemisphere)

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

Finderscope 9 x 50

SKYWATCHER FLATTENER & REDUCER FOR 120ED refractor With a 2 x BarlowThe 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
