TS-Optics ADC - Atmospheric dispersion corrector

TS-Optics ADC - Atmospheric dispersion corrector

Visit TS-Optics ADC (Atmospheric Dispersion Corrector) is designed to significantly improve sharpness and detail during planetary or lunar observation and imaging, particularly when the stars are close to the horizon. Thanks to two adjustable prisms, it compensates for chromatic shift induced by the atmosphere, delivering sharper, higher-contrast images.

Highlights

• Atmospheric dispersion correction eliminates color fringing, improves sharpness and detail.
• Easy to use adjustment via a lever without removing the eyepiece or camera.
• Ultra-compact design only 29 mm high (T2 to T2), binocular compatible.
• Graduated scale Reproducible settings for practical use.
• Universal connections T2 (M42x0.75) and 1.25″ cast on both sides.
• High light transmission up to 99 % thanks to high-quality multi-layer prisms.
• Versatile observation and photography of planets, the Moon and double stars.

Why an ADC?

Near the horizon, light passes through a thicker atmosphere. Each wavelength is refracted differently (red vs. blue), creating a visible chromatic shift: planets appear blurred and surrounded by coloured bangs. The TS-ADC corrects this effect in real time, bringing the colors back to the same → focal plane. finer, more contrasting and detailed stars and planets.

Compatibility and connections

The system consists of three components screwed together via T2 threads:

• Telescope side 1.25″ adapter with T2 male thread
• Corrective body T2 female thread (input) and T2 male thread (output)
• Eyepiece/camera side 1.25″ adapter with T2 thread

It mounts easily on any telescope accepting T2 or 1.25″. Cameras and eyepieces connect via T2 or standard thread.

In a nutshell

This ADC is the essential solution for all near-horizon planetary and lunar observation and imaging. Compact, easy to use and compatible with the majority of setups, it allows you to obtain sharper, higher-contrast images without colored bangstransforming the quality of your astrophotography and observation sessions.
