Exclusive Sandwich Mirror Technology
The lightweight sandwich mirror design cools dramatically faster than solid mirrors, minimizing thermal
gradients and eliminating a major source of image distortion. Unlike fan-based cooling, this passive
design achieves rapid and stable thermal equilibrium naturally — without introducing vibration.
Why this matters: One of the primary limitations in large-aperture telescopes is "mirror seeing" —
turbulence caused by temperature differences between the mirror and the surrounding air. In changing
conditions, a thick solid mirror may never fully reach equilibrium, preventing it from achieving its
full optical performance.
The sandwich mirror design minimizes this effect, allowing the system to reach optimal performance
quickly and consistently, delivering sharper and more stable views without the need for active cooling.
GoTo Drive System
Built-in WiFi and Bluetooth 4.2. Smart Hand Controller with ~30,000 objects. INDI, ASCOM LX200, Sky
Safari, and Stellarium compatible. Telescope encoders for precision pointing and tracking. Advanced 1-9
star alignment with sidereal, lunar, and solar tracking rates.
Enhanced Optical Coatings
96% enhanced reflective coatings on both primary and secondary mirrors with precision-controlled
dielectric layers. Maximum light throughput for bright, contrast-rich images on deep-sky targets.
All Metal Construction
CNC-machined 6063-T6 aluminum alloy truss tubes, structural steel mirror cell, and aluminum alloy OTA
and mount structure. Finished with environmentally friendly black powder coating.
Sharper images with about 30% less coma — no coma corrector needed at all. Smaller central obstruction
(2.76" vs 3.1" for f/4.5). And you save $300.
Advantages of f/4.5
No ladder needed for most people — the eyepiece stays conveniently close to the ground. Wider field of
view for sweeping panoramic observations.
Both f/5 and f/4.5 provide excellent views. The f/5 is perfect for the most demanding observer without a coma
corrector. The f/4.5 provides a wonderful wider view. With our unique two-section truss tubes for f/5, both are
equally portable and strong. Please note that some counter weight will be required for f/5 at the bottom (not
provided).
Wireless Connectivity
WiFi 802.11 b/g/n with built-in web interface accessible from any browser. Bluetooth 4.2 for ASCOM
connection. Direct wireless support for Sky Safari and Stellarium.
Smart Hand Controller
~30,000 objects database. Full control: initialization, configuration, alignment, slewing, and GoTo. iOS
and Android Virtual Handpad apps also available. INDI and ASCOM (LX200) driver support.
Precision Tracking
Telescope encoders for extra pointing and tracking accuracy. Advanced 1-9 star alignment. Sidereal, lunar,
and solar tracking rates. Park/Unpark function and spiral search. Slewing speeds up to 4 degrees/second.
