EvWaCo

Photographing exoplanets requires the use of a coronagraph, a device that separates the light of the exoplanets from their host stars, and adaptive optics, which correct for distortions caused by atmospheric variability.

The Evanescent Wave Coronagraph (EvWaCo) is a light-separating device composed of two key components: an innovative light-shielding system designed to minimize starlight interference and an adaptive optics system. It will be installed at the Thai National Telescope (TNT) at the Thai National Observatory, serving both as a demonstration of high-resolution imaging technology and as a means to enhance the capabilities of Thailand’s telescopes.
