iOptron CEM70 / CEM70G — Medium Payload Center-Balance Mounts

Following up on the success of the iOptron CEM60 center balance equatorial mount, we at iOptron are excited to introduce two new medium payload center balance mounts. The CEM70 and CEM70G are new standard bearers for equatorial mounts in the 31.8 kg payload segment. Both models are packed with advanced features; however, the CEM70G is the first of its type with an onboard optical guiding system, increasing tracking accuracy while streamlining components for a more portable imaging setup.

Retaining the inherent properties of the center balance design, these relatively compact medium payload mounts deliver what astronomers expect in an efficient, accurate, portable mount. With precise GOTO pointing and accurate tracking (PE ≤ ±3.5 arcsec) the CEM70 is a solid performer for observers and imagers alike.

Innovative operational features such as the internal iPolar electronic polar scope, easy-lock drive gear engagement (levers large enough to use with gloves), and an advanced cable-management system for the mount, iPolar, guider and camera cumulatively assure users the CEM70 and CEM70G are designed with their needs in mind.

iOptron CEM120

The All NEW iOptron CEM120

An extraordinary innovation in mount design...Now with a new payload!

Recognizing the growing demand for an accurate and stable, equatorial mount with the versatility to carry larger instruments and more complex imaging arrays, we created the iOptron CEM120. It offers the benefits of our revolutionary “center balance” design: stability, accuracy, and smooth mechanical operation, while capable of carrying a payload up to 52 kg. The “center balance” design’s natural stability is due to its focusing the mount along with payloads weight directly over the center of the pier or tripod.

The CEM120's performance is demonstrated by its low periodic tracking error of ±3.5 arc seconds. Along with the stability aspect, the CEM120 features an advanced cable management system consisting of more ports in more locations preventing tangle ups and reducing the chance of fractured cables. It also adds some new features to the CEM family like Wi-Fi and LAN for remote operation and easy to use, reliable clutches on both axes.

They also add some new features to the CEM family like Wi-Fi and LAN for remote operation and easy to use, reliable clutches on both axes.

The CEM120EC2 utilizes two high resolution encoders, one on each axis. The two encoders enable the mount to perform dual axes tracking. With advanced sky modeling the CEM120EC2 will be able to account and adjust for polar alignment error as well as changes in atmospheric (refractive) distortion. Fixed home sensors on each axis, allow the mount to save alignment models after power off too to be used on future nights.

$2,699.00

Like their predecessors, the C262A3 is designed with portability in mind, weighing in at only 4.5kg it can support up to a 12kg payload an incredible 2.6 mount weight to payload ratio. The key to enable such ratios is the CEM design focuses the mount and payload weight directly on the center of the tripod rendering “natural stability”.

Building on the legacy of earlier CEM models we have added features for convenience and functionality. A positive lock gear engagement system (easy to use even when wearing gloves), Built-in Wi-Fi enabling unparallel connectivity and recordable permanent periodic error correction (PPEC) to repeat optimal PEC training sessions. Regarding functionality the C262A3 delivers precise pointing and accurate tracking. The CEM26 sets the new standard for compact equatorial mounts.

The center-balanced design mount puts the weight of the payload at the center of gravity allowing for greater natural stability. Other features include an adjustable counterweight bar to prevent obstruction with the tripod. And polar aligning is quick and accessible all the time since the polar scope is not blocked by the declination shaft.

The C262A3 is equipped with the latest advanced GOTONOVA® GOTO technology, making it one of the most powerful and accurate GOTO mounts available. Its database includes over 212,000+ objects. The Go2Nova® Hand Controller is intuitive to use and its large 4-line LCD screen simplifies the process of setting telescopes and locating objects.

The CEM26A mount has an integrated electronic polar finder scope known as the iPolar. This tool ensures the accurate alignment of a telescope, even when the pole star is obscured. It comes with a 1.5" heavy duty stainless steel tripod and an aluminum carrying case.

$10,749.00

The All NEW iOptron CEM120EC

An extraordinary innovation in mount design...Now with a new payload!

Recognizing the growing demand for an accurate and stable, equatorial mount with the versatility to carry larger instruments and more complex imaging arrays, we created the iOptron CEM120EC. It offers the benefits of our revolutionary “center balance” design: stability, accuracy, and smooth mechanical operation, while capable of carrying a payload up to 52 kg. The “center balance” design’s natural stability is due to its focusing the mount along with payloads weight directly over the center of the pier or tripod.

The CEM120EC's performance is demonstrated by its low periodic tracking error of <0.15 arcsec RMS. Along with the stability aspect, the CEM120EC features an advanced cable management system consisting of more ports in more locations preventing tangle ups and reducing the chance of fractured cables. It also adds some new features to the CEM family like Wi-Fi and LAN for remote operation and easy to use, reliable clutches on both axes.

Optional Extra's

Optional heavy duty Tri-Pier 360 and Permanent Pier are available for order.

/product/ioptron-tri-pier-360

Optional Tri-Pier adapter for light weight payload ( 8036-120) is also available for $239. It can be modified for permanent pier mounting.
