The ASA 1-Meter Telescope – Wide Field f/2.5 is ideal for wide field imaging and all-sky surveys. It’s designed with precision and fast, on-the-fly adjustments in mind.

Featuring a 5-lens corrector and motorized focusing with absolute encoders, the WF1000 has an equatorially mounted fork system with direct drive motors and absolute encoders on both axes.

The main mirror is also equipped with absolute encoders for pinpoint remote collimation.
