For planetary observation ADC ZWO 1.25 "Atmospheric Dispersion Corrector
Eliminate atmospheric chromatic aberration filters.
Special for astronomical planet photography
The English name of ADC is called Atmospheric Dispersion Corrector.
Chinese is the atmospheric aberration correction mirror
Planet photographers know that photos taken with low planet angles have red and blue edges.
This is caused by the color difference of the atmosphere, just like the general refraction mirror
Look at the image below using ADC and Mars without ADC
The angle of Mars in the tester's area is only 44 degrees. The lower the angle, the more serious the chromatic aberration caused by the atmosphere.
Atmospheric chromatic aberration not only leads to color separation, but the more prominent problem is the loss of detail.
Colors can be recombined by post-software, and image details are only improved with ADC
