Tecnosky ADC Atmospheric Dispersion Corrector
DESCRIPTION
The Tecnosky Atmospheric Dispersion Corrector (ADC) is designed to eliminate chromatic shifts caused by the atmosphere, which distort planetary images especially at low elevations. It uses a pair of precision-aligned 2.5° K9 glass prisms to recombine the wavelengths of light and sharpen planetary detail.
Its advanced multi-coating ensures a reflection rate below 0.3 %, across a wide 350–700 nm spectrum. This makes it particularly effective in LRGB imaging, where the luminance channel benefits from enhanced clarity. The ADC is compatible with 1.25" eyepieces and planetary cameras, and offers male and female T2 threads for versatile setups.
