ZWO ADC Atmospheric Dispersion Corrector
The ZWO Atmospheric Dispersion Corrector reduces atmospheric chromatic aberration for planetary and lunar imaging, featuring H-K9L prisms with λ/10 surface accuracy and a 2° deviation angle for precise corrections.
Shipping Calculator
The ZWO Atmospheric Dispersion Corrector (ADC) is designed to reduce chromatic aberration caused by Earth's atmosphere during planetary and lunar observations. It employs two adjustable prisms made from H-K9L (equivalent to Schott BK7) glass, each with a surface accuracy of λ/10 at 632.8nm and a deviation angle of 2°. The ADC features T2 male and female threads, facilitating integration with various optical setups. By fine-tuning the prisms' positions, users can counteract atmospheric dispersion, resulting in clearer and more detailed images.
