i-OPTRON GEM28 GoTo Mount with iPolar and LiteRock Tripod

iOptron GEM28 w/ iPolar & 1.5” Tripod (Model: G281A1)

Authorized Distributor: Modern Telescopes – India’s Largest Telescope Store

The iOptron GEM28 is a compact, next-generation German Equatorial Mount engineered for astronomers who demand precision, portability, and performance—whether for serious astrophotography or refined visual observation.

Weighing just 4.5 kg (10 lbs) yet capable of carrying an impressive 12.7 kg (28 lbs) payload, the GEM28 delivers a remarkable 2.8:1 payload-to-mount weight ratio. Drawing on advanced mass-reduction techniques proven in iOptron’s celebrated CEM series, this mount sets a new benchmark for lightweight German EQ mounts, especially for users operating at higher latitudes who prefer the classic GEM design.

Designed for Precision & Convenience

The GEM28 builds upon iOptron’s legacy with a host of modern features that enhance both usability and accuracy:

• Positive-lock quick-engagement clutches – easy operation even with gloves

• Spring-loaded precision gear system for stable, backlash-free performance

• Low periodic error (< ±12 arcsec) ideal for long-exposure imaging

• Permanent Periodic Error Correction (PPEC) to record and repeat optimal PEC training

• Synchronous belt transmission for smooth, quiet slewing and tracking

Integrated iPolar™ – Accurate Polar Alignment Anywhere

The GEM28A version features the integrated iPolar™ electronic polar scope, allowing fast and extremely accurate polar alignment, even when Polaris is not visible. This is a game-changer for urban observers, southern-horizon users, and permanent installations.

Advanced GoTo & Connectivity

Powered by Advanced GOTONOVA® GOTO Technology, the GEM28 offers exceptional pointing accuracy with a massive 212,000-object database.

• Go2Nova® 8409 Hand Controller with large, easy-to-read 4-line LCD

• Built-in Wi-Fi for wireless control via PC, tablet, or smartphone

• USB port for firmware upgrades and ASCOM-based computer control

• ST-4 autoguiding port for precision guiding

You’ll never run out of celestial targets—and you’ll reach them quickly and accurately.

Rock-Solid Tripod & Build Quality

Included with this configuration is a 1.5-inch heavy-duty stainless steel tripod, offering excellent vibration damping and field stability. The mount features an all-metal CNC-machined and cast body, finished with durable powder coating for long-term reliability.
