CHI-1 is a Planewave CDK24, a 61-cm telescope with Corrected Dall Kirkham optical design, situated in the Rio Hurtado Valley, Chile. It is equipped with a set of Astrodon astrophotography filters as well as Sloan photometry filters and it's, therefore, an excellent choice for both scientific applications and astrophotography of deep-sky objects.
