Avalon LINEAR Bluetooth Black mount (Avalon Instruments, SKU: AV-1LNRB02) is a German equatorial mount (GEM) for observing and astrophotography. Belt transmissions on the right ascension and declination axes allow direction changes without taking up the backlash typical of worm drives. This version is equipped with the StarGo GoTo Bluetooth system.
When planning a session, account for meridian passage and a possible telescope-side change, in accordance with the German equatorial geometry and control settings.
