Welcome to
THE NEXT GENERATION
Equatorial mount with harmonic drive
CRUX series
A next-generation photometric mount that does not require a counterweight."High Torque & Zero Backlash" Brought About by Harmonic Drive
Please experience the outstanding portability.
Features of the CRUX equatorial mount series
Lightweight and compact
A lightweight feeling that overturns conventional wisdom. The compact body makes it highly portable. You will be able to enjoy observations and photography more easily by reducing the amount of luggage you need to carry during mobile observations.
No balance weight required
Equipment heavier than the main body weight can be operated without weight. No more carrying around heavy weights. It is lightweight enough for women to use with confidence.

The CRUX 170HD is an equatorial mount with extremely high portability, weighing approximately 4.9kg excluding weights. The weight that can be loaded is about 10 kg without a counterweight, and if you add a small weight of about 3.7 kg as an option, you can mount a lens barrel of about 24 kg. Also, the included dedicated controller Titan TCS not only combines intuitive operability and excellent motor control, but also has unrivaled versatility.

The CRUX 200HD is an equatorial mount that weighs approximately 13kg excluding weights, which is more than 3.5kg lighter than the Takahashi EM-200 equatorial mount. The weight that can be loaded is about 18kg without a counterweight, and with an optional weight of about 15kg, it is possible to mount a 40kg lens barrel. Although the mountable weight exceeds Vixen's AXD equatorial mount and Takahashi's NJP equatorial mount, it is overwhelmingly light, so moving observation with a large aperture telescope was about to give up.・It is an equatorial mount that enables shooting. The included dedicated controller, Titan TCS, not only combines intuitive operability and superior motor control, but is also unmatched in versatility.

The CRUX320HD weighs about 25kg without weights, and can be loaded with about 23kg without a balance weight. Despite being half the body weight of Takahashi's EM500 equatorial mount, the weight that can be loaded surpasses its specs.
We also offer a Meridian type with an extended right ascension axis that does not require reversing the lens barrel even for continuous shooting that crosses the meridian.

The flagship model CRUX T-4000 is a monster-class equatorial mount that can carry a whopping 180kg. The total weight of the main body is about 50 kg, but it has a structure that can be divided into two so that it can be used for mobile observation.

CRUX dedicated controller
The specially designed controller "TiTan TCS" is a very versatile controller. A special PEC function controls the cyclic error of the harmonic drive completely.
As a result, the CRUX equatorial mount achieves zero backlash, high guide response, high-precision tracking, and high-speed introduction, making the most of the advantages of harmonic drive.
CRUX is an equatorial mount with high specs that have never been seen before.

RS232 x 2 ports, USB x 2 (Type-A x 1, mini x 1). In the future, it will be possible to use it as a USB hub and connect external devices such as a motor focuser.
Built-in Bluetooth communication device
Titan TCS has a built-in Bluetooth communication device. It links with a computer via wireless communication with star map software such as Stella Navigator. Wireless guidance is also possible via ASCOM.
Built-in about 14,000 celestial bodies information
About 14,000 celestial objects are stored inside the controller (stellar data, Messier catalog, NGC catalog, IC catalog, Coldwell catalog, Sharpless catalog). Therefore, it can be installed automatically without connecting to a computer.
LX200 command
The communication protocol uses LX200 commands. Therefore, ASCOM drivers for LX200 can be used. The recommended ASCOM driver for mounting is “Advanced LX-200 Driver (Generic, not for Meade scopes)”.
