Chile Two Wide-Field Telescope

The Chile Two Wide-Field system is Slooh's largest telescope at its southern hemisphere observatory in Chile and is due to come online in January 2020. The telescope's 17" (432mm) primary mirror gives it superb light-gathering capabilities, making it ideal for the myriad of southern hemisphere celestial gems, including galaxies, nebulae, and star clusters.
