The Astro-Physics 1600GTO is an observatory-grade mount with a weight capacity of 220 lbs, manufactured and assembled in the USA and individually tested to exceed periodic error specification of 5 arc seconds (+/- 2.5 arc sec.) The mount features spring-loaded worms maintaining full contact under all guiding and slewing conditions, a precision balance mechanism allowing full backing off the worm from the worm wheel, and very low backlash gear train that eliminates Dec reversal delays and provides high position accuracy during guiding With the absolute encoder upgrade, periodic error can be reduced below 0.2 arc-seconds The mount can be powered with a commonly available 12V battery for portable use or standard filtered regulated power supplies in observatory settings, and controlled via optional GTO Keypad, PC computers, Mac computers, or mobile smart devices
