ZWO 1.25" ATMOSPHERIC DISPERSION CORRECTOR mechanical accessory ESATTO 2" has a 51mmThe ZWO Atmospheric Dispersion Corrector is used to reduce the effect of atmospheric dispersion on lunar and planetary images. By aligning two prisms made of H K9L (BK7 equivalent) glass, you are able to significantly compensate for the optical distortions and aberrations that come with viewing the planets at lower elevations. The ZWO ADC is manufactured with UV friendly AR coating. The ADC works best when paired with an optical system slower than f
