WF1000 f2.5 - Datasheet

ASA WF1000 f2.5 Wide Field telescope system


ideal platform for widefield imaging! The WF1000 f2.5 telescope is the ideal platform for wide ﬁeld imaging and all-sky surveys. The WF1000 f2.5 features a 5-lens corrector and motorized focusing with absolute encoders. The main mirror can be collimated fully electronic to allow an easy and fast remote collimation. The WF1000 ensures precise focus and high-resolution data acquisition of the night sky – in the shortest possible time!
