EQ-AL55i Pro Equatorial GoTo Mount – Serious Performance, Unbeatable Value 

Looking for a portable, feature-packed equatorial mount that won’t break the bank? The EQ-AL55i Pro is the perfect solution for serious observers and astrophotographers who need a lightweight, capable, and future-proof platform. Whether you’re just getting started or upgrading your rig, this mount delivers GoTo accuracy, solid tracking, and advanced connectivity without the premium price tag. 

With a 22-pound payload capacity, built-in WiFi & Bluetooth, and a SynScan GoTo system with over 42,900 objects, this mount is ready to take your stargazing and imaging to the next level. Plus, its fully enclosed motors, flexible counterweight system, and wide latitude range (0°-90°) make it an excellent option for observers worldwide—especially those in lower latitudes. 

Feature Breakdown – What Makes It Stand Out? 

  • Advanced GoTo Functionality & Precision Tracking 
  • SynScan GoTo System – Navigate the night sky effortlessly with a 42,900+ object database, covering everything from the Moon and planets to deep-sky galaxies, nebulae, and clusters. 
  • Dual-Axis Tracking – Ensures smooth, precise tracking for both visual astronomy and astrophotography, keeping objects centered in the field of view. 
  • Built-in Illuminated Polar Scope – Get precise polar alignment without the hassle, making setup easier for long-exposure imaging. 
  • Latitude Range: 0°-90° – Designed to work for astronomers at all latitudes, including those near the equator. 

Modern Connectivity – No Hand Controller Needed! 

  • Built-in WiFi & Bluetooth – No messy cables. Control your mount wirelessly with the SynScan Pro app for iOS & Android or via ASCOM for PC-based control. 
  • Smartphone, Tablet, or PC Control – Skip the hand controller (sold separately) and use your preferred device instead. 

Designed for Versatility & Stability 

  • 22-Pound Payload Capacity – Supports a wide range of OTAs, including small-to-mid-size refractors, Newtonians, and SCTs. Perfect for serious observing and deep-sky astrophotography. 
  • Two Counterweights Included – One 7.5-lb and one 4-lb counterweight, allowing for better balancing flexibility depending on your setup. 
  • Multiple Counterweight Bar Positions – Adaptable for different optical tube and accessory configurations. 
  • Adjustable Steel Tripod – Sturdy, height-adjustable steel legs ensure a solid and vibration-free platform. 

🚀 Built for Observers & Astrophotographers Alike 

  • Fully Enclosed Motors – Unlike previous models, the EQ-AL55i Pro features fully encased motor housings, protecting them from dust, debris, and accidental bumps. 
  • Guide Scope Ready – Equipped with a guidescope port for precision guiding during long-exposure imaging sessions. 
  • SNAP Port for Camera Control – Take automated exposures directly through the mount for hands-free imaging. 
  • Pier Extension Compatible – Need extra height? The optional pier extension (sold separately) ensures your setup is adaptable to any observing situation. 

Power & Accessories 

  • DC Power Cord Included – Ready to go straight out of the box with your 12V DC power supply. 
  • Pier Extension, OTA, and Hand Controller Sold Separately – Customizable to fit your exact needs. 

 Redesigned from the EQM-35, Optimized for Today’s Astronomers 

The EQ-AL55i Pro takes inspiration from the highly popular EQM-35 and improves on its design in almost every way. By enclosing the motor housings, integrating wireless control, and refining its balancing system, this mount is an ideal grab-and-go equatorial platform for anyone looking to elevate their observing or imaging game. 

Whether you're a visual astronomer wanting precision tracking or an astrophotographer needing a reliable mid-range mount, the EQ-AL55i Pro delivers the performance you need in a package you can actually carry.
