COATLI is a robotic 50-cm telescope at the Observatorio Astronómico Nacional in Mexico.

COATLI is currently operating with an interim instrument, a CCD with a field of view of 12.8 × 8.7 arcmin with BVRIw filters. However, our medium-term aim is to install a fast-guiding imager which will provide 0.3 arcsec FWHM images over a field of at least 1 arcmin and coverage of a large fraction of the sky.

For more details, see our article Watson et al. 2016, Proc. SPIE, 9908, 990850: “COATLI: an all-sky robotic optical imager with 0.3 arcsec image quality” (ADS|SPIE|Local).
