The iOptron HST MiniTracker is an ultra-compact single-axis star tracker featuring innovative strain wave gear (SWG) technology, designed for astrophotographers who prioritize portability without sacrificing tracking performance. Weighing just 1.75 lbs while supporting up to 8.8 lbs of camera and lens equipment with no counterweight required, it enables smooth, silent tracking across four modes (sidereal, lunar, solar, and half-rate) for wide-field night sky imaging. Built with a CNC-machined metal housing and powered by an internal rechargeable battery, AAA batteries, or external USB-C power, the MiniTracker fits in the palm of your hand yet delivers the precision tracking needed for extended long-exposure celestial imaging.
