ZWO NEW 1.25" ADC (Atmospheric Dispersion Corrector)

The ZWO ADC actually does work well. It takes a bit of practice and some searches through the internet on how to use, but if planets are low in the sky the ADC will provide a better image.

ข้อดี: Can be used with a small DSLR.
Does truly correct for atmospheric dispersion.
Works great on planets in particular.

ข้อเสีย: There is no manual or usage instructions. Some basic instructions and diagrams would be highly helpful.
