SVBONY SV199 - Corrector for Atmospheric Dispersion for Planetary Observation and Photography

The atmospheric dispersion corrector (ADC) reduces color changes caused by atmospheric dispersion and enhances the imaging effect of planets, especially those at low altitude.

Features

• Pair of prismatic lenses with a double coating process to reduce light loss;
• Broadband anti-reflective coating (300 nm to 700 nm);
• 1.25-inch barrels on the camera side and the eyepiece with male T2 threading;
• Easy adjustment via T2 threading and 1.25-inch barrels;

Functions

The atmospheric dispersion corrector uses two prisms of a minimum quality of 1/4λ BK7 to correct false colors introduced by the Earth's atmosphere.

• Declination adjustment of 4.5 degrees;
• Adjustment scale to fine-tune dispersion correction;
• Coaxial locking interface to ensure adequate coaxiality;

Benefits

The use of the atmospheric dispersion corrector significantly improves the sharpness of planetary and lunar images, particularly in the luminance channel during LRGB imaging.
