Description
Product Overview
The BuiltAstro Telescope Setting Circle is a compact, wireless device that brings modern sensor technology to traditional telescope alignment. Utilizing a high‑precision gyroscope and magnetometer, it continuously measures azimuth and altitude, delivering real‑time positional data to your smartphone or tablet via built‑in Wi‑Fi and Bluetooth. The unit measures 3 x 2.2 x 2.46 inches and weighs only 6.7 ounces, making it lightweight yet robust. It includes a lithium‑ion battery (included), a built‑in bubble level, mounting brackets, and a carrying pouch for easy transport. Designed for Dobsonian and alt‑azimuth mounts, the quick‑release system allows fast installation and removal, so you can switch between telescopes in seconds.
Usage
Whether you are setting up a backyard Dobsonian for a family night under the stars or fine‑tuning an alt‑az mount for deep‑sky imaging, the BuiltAstro Setting Circle streamlines the process. After mounting, simply connect to the device with the SkySafari Plus/Pro app; the app displays live azimuth and altitude readings, letting you point the telescope at any object with confidence. The wireless operation eliminates the need for cumbersome cables or physical encoders, making it ideal for portable observing sessions, field trips, and educational workshops.
