The Sky-Watcher Syn Scan Star Wand can be aimed anywhere in the sky to command a Syn Scan AZ, EQ or AZ-EQ mount (provided it has a Syn Scan handset fitted) to automatically move to that position. It comes with a pointing device & a Wi-Fi adaptor that plugs into the aforementioned Syn Scan handset. To precisely locate the desired object; you will have to make slewing adjustments with the handset controls. This is a fun, rewarding & educational system as you have to navigate to the final object yourself. The Star Wand is capable of commanding more than one mount at the same time with extra Star Wand Wi-Fi adaptors. It is compatible with Syn Scan V3, V4 & V5 handsets. Please note that for V3/V4 firmware updates may be required. This is a class 2 laser product & requires one 18650 rechargeable lithium-ion battery & a battery charger which are sold separately.
