StarLock — the heart of the LX850 — is the revolutionary new technology that makes target acquisition and ultra-precise guiding corrections a snap. StarLock is an integrated two-camera sensor array that provides four primary functions.

Full-Time Automatic Guide Star Selection and Auto-Guiding - Any time the telescope is slewed to a target, StarLock automatically identifies a suitable guide star as faint as 11th magnitude and locks on. Once locked on, the StarLock will provide guide corrections until you slew to another target or turn it off. It’s all automatic. And unlike standard autoguiders that issue guide corrections in the form of speed and time, the StarLock speaks directly with the motor controllers providing specific commands. The result is more accurate and faster guide corrections.

Ultra-Precision Pointing – StarLock uses its two cameras to refine pointing to an incredible accuracy of one arc-minute, which ensures the object you select will end up on your imaging sensor, a must of those faint objects you can not see visually to confirm position.

Drift Alignment Assist – After alignment, StarLock uses its two cameras to automatically select and GOTO two candidate stars then uses its 80mm f/5 guiding optic to snap a 30 second exposure. The telescope then calculates the distance the mount must be adjusted to be precisely aligned to the celestial pole and then moves the optical tube the calculated distance so you can re-center the candidate star using the altitude and azimuth controls on the mount head. This dramatically speeds up the drift alignment process.

Lightswitch Alignment – Borrowing from our award-winning Lightswitch line of telescopes, the LX850 and StarLock can select and automatically center alignment stars using its two cameras, thereby taking the guesswork out of alignment.
