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

COATLI is currently operating with the HUITZI f/8 instrument, a EMCCD with a field of view of 11.9 × 11.9 arcmin with griz broad-band filters and 470/10, 640/10, and 656/3 narrow-band filter. However, our medium-term aim is to install a fast-guiding imager which will provide 0.35 arcsec FWHM images over a field of at least 4 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).
