ZWO ADC WAS VOTED AS  “HOT SKY PRODUCT – 2017” BY SKY&TELESCOPE MAGAZINE!

The first ADC made by amateur astronomers for amateur astronomers! A must-have for serious planetary observers and photographers...

The ZWO Atmospheric Dispersion Corrector is a good alternative to more expensive similar devices for observing and imaging objects at low altitude.

The inner planets are always very near to the horizon therefore they cannot be observed at high altitudes. Even the outer planets appear frequently in not the best locations (i.e. at low altitude) where an ADC would be very helpful to correct the effects of atmospheric disparison.

The ZWO ADC includes two high quality prisms of 1/10 Lamda surface quality. By a certain positioning of these prisms you can counteract the effects of atmospheric dispersion, i.e. reduce or possibly even completely eliminate the false colour introduced by the earths atmosphere.
