ATLAS Series SH20 Harmonic Drive Equatorial Mount from ToupTek Astro
The SH20 combines a BLDC servo motor, harmonic reducer, and 18-bit high-precision encoder to deliver smooth motion, precise positioning, and responsive guiding. With a peak-to-peak periodic error of ≤20″, each mount comes with an individual PE test report, providing reliable tracking performance for long-exposure deep-sky imaging.
Designed to balance portability and payload capacity, the SH20 weighs just 5.1 kg (11.2 lb) while supporting up to 20 kg (44 lb) @ 20 cm without counterweights, or 30 kg (66 lb) @ 20 cm with counterweights. Its EQ / Alt-Az dual modes can be switched with a single click without restarting, making it suitable for deep-sky imaging, visual observation, EAA, sky surveys, and Solar System imaging.
The SH20 also features ToupTek’s self-developed control system, supporting PC, Android, and iOS, together with the ASCOM, INDI, and INDIGO ecosystems. Wi-Fi, Bluetooth, and USB-C connectivity provide flexible control and seamless integration with popular imaging workflows, including NINA, SharpCap, KStars, MaxIm DL, and StellaVita.
Precision Servo Harmonic Drive
The BLDC servo motor, harmonic reducer, and 18-bit encoder deliver near-zero-backlash transmission, smooth motion, and precise positioning. High-response guiding enables fast, accurate corrections, with a peak-to-peak periodic error of ≤20". Each SH20 includes an individual PE test report for reliable long-exposure imaging.
EQ / Alt-Az Dual Modes
Switch between Equatorial (EQ) and Alt-Azimuth (Alt-Az) modes with a single click—no restart required. EQ mode is ideal for deep-sky astrophotography, while Alt-Az mode suits visual observation, EAA, sky surveys, and Solar System imaging.
Lightweight Design, High Payload Capacity
Weighing just 5.1 kg (11.2 lb), the SH20 supports up to 20 kg (44 lb) @ 20 cm without counterweights and 30 kg (66 lb) @ 20 cm with counterweights. Compatible with both Vixen and Losmandy dovetails for a wide range of imaging setups.
ToupTek Self-Developed Control System
ToupTek’s self-developed control system supports PC, Android, and iOS, with ASCOM, INDI, and INDIGO compatibility. Wi-Fi, Bluetooth, and USB-C provide flexible control via the mobile app, PC, or MHC hand controller, with support for N.I.N.A., SharpCap, KStars, Maxim DL, and StellaVita.
