iOptron CEM26EC “Center Balanced” GoTo Mount with High Precision Encoders, iPolar, Hard Case, and 1.5" Tripod
Item #: C264A1
Ultra-precise tracking meets ultra-portable design in the iOptron CEM26EC. This high-performance equatorial mount delivers real-time periodic error correction via high-resolution encoders, achieving an incredible < 0.3 arcsecond RMS tracking error—and it does so from a mount head weighing just 10.4 pounds. Whether you’re a visual observer who wants rock-solid tracking all night long or an astrophotographer chasing razor-sharp stars across long exposures, the CEM26EC makes accuracy easy.
This version includes the advanced iPolar electronic polar scope, a hard case for safe transport, and a sturdy 1.5" stainless steel tripod that offers solid support in a more compact footprint.
High Precision, No Compromises
At the core of the CEM26EC is a pair of high-resolution optical encoders that deliver continuous, real-time correction of periodic error. These encoders actively monitor gear motion and correct deviations before they affect tracking—eliminating the need for PEC learning cycles and enabling clean, elongated exposures even at long focal lengths.
This tracking accuracy—typically under 0.3 arcseconds RMS—makes the CEM26EC the best portable tracking mount in the iOptron line, and one of the most precise compact mounts on the market today.
The Center-Balanced Advantage
The CEM26EC uses iOptron’s unique center-balanced “Z” design, which places the payload directly over the tripod’s center of gravity. This architecture improves natural stability, reduces required counterweights, and minimizes flexure during tracking and slewing. It's the kind of thoughtful engineering that pays off in real-world field use—especially when you're on uneven ground or traveling light.
Despite its small footprint, the CEM26EC can carry up to 26 pounds (11.8 kg) of gear, making it ideal for everything from compact imaging rigs to 5" refractors and 6–8" SCTs.
iPolar for Fast, Accurate Setup
Also included is the iOptron iPolar electronic polar scope, which provides a fast, user-friendly way to achieve precise polar alignment—whether or not you can see Polaris. iPolar overlays your actual polar axis position on a star map, guiding you through a quick visual or imaging alignment. Once you’ve used it, you’ll wonder how you ever lived without it.
Designed for Visual Use and Imaging Alike
Visual observers will enjoy the quiet belt-driven motors, intuitive hand control, and precise GoTo slewing. The Go2Nova 8409 hand controller comes preloaded with over 212,000 objects, from Messier, NGC, and IC catalogs to variable stars and exoplanets. Whether you’re touring open clusters or hopping to faint galaxies, the CEM26EC gets you there fast and keeps your target centered.
Astrophotographers benefit from encoder-corrected tracking, permanent PEC, low power draw, and a rich suite of connectivity options, including:
All of this with power consumption as low as 0.5 amps while tracking, making the CEM26EC a dream for battery-powered field sessions.
Tripod and Case: Field-Ready Convenience
This version includes the 1.5" stainless steel tripod, a lighter-weight alternative to the 1.75" LiteRoc version. It's strong enough for most mid-weight visual and imaging loads, and makes for a smaller, more manageable system—especially if you're carrying gear in and out of tight spaces.
A custom-fit hard case is also included for the mount head, making storage and transport secure and easy.
Observing Tip
For visual users running heavier OTAs—or those in windy or vibration-prone conditions—you might consider upgrading to iOptron’s 1.75" LiteRoc tripod for added rigidity. But for most users, the included 1.5" version provides excellent support and makes the mount easier to carry, especially on solo trips or airline travel.
Final Thoughts
The iOptron CEM26EC with iPolar, encoders, hard case, and 1.5" tripod is a portable mount with serious pedigree. It’s built for those who expect exceptional tracking, quiet and accurate GoTo performance, and practical field readiness. Whether you’re a traveling imager or a backyard observer seeking pinpoint precision, this version of the CEM26EC delivers.
