Sky-Watcher EQ-AL55i Pro Overview Video: Features, Specs, and More
A New Standard of Performance for Beginner-Friendly Mounts!
The EQ-AL55i Pro is Sky-Watcher's mid-size, entry-level GoTo equatorial mount, and it packs a serious punch. Even at such a small size it supports up to 22 pounds of equipment, which covers most refractors, small Newtonians, and compact imaging setups. The mount ships complete with two counterweights, a steel tripod, an illuminated polar scope, and a DC power cable.
This is a fully motorized GoTo mount that Sky-Watcher redesigned from the previous generation of mounts known as the EQM-35. The EQ-AL55i is controlled through the SynScan Pro app on a phone or tablet using its own WiFi signal. An optional hand controller is available if you prefer to use one, but the EQ-AL55i is designed to be used without it. An optional pier extension is also available for anyone using a longer telescope or who resides in lower latitudes.
Features Built for Astrophotographers
App-Based Wireless Control


Built-in WiFi connects directly to the SynScan Pro app on iOS or Android. The app handles alignment, slewing, and tracking without a hand controller. It gives you access to more than 42,000 objects, location data, and fantastic curated suggestions for nightly targets. This also means fewer cables and no LCD displays to worry about in cold weather.
Built for Astrophotography


The EQ-AL55i Pro builds on what made earlier entry-level equatorial mounts popular and takes them further. Fully enclosed motor housings add durability in the field. A dual-position counterweight bar makes this mount a great option for traveling, and a 22 lb payload means it can handle a wide variety of equipment.
Connectivity Made Simple


Connect to a PC via USB-C and control the mount from planetarium and capture software. It also supports ASCOM telescope control for compatibility with popular imaging applications. If you prefer to work without a laptop, the built-in guide port lets you autoguide using a standalone guide camera and controller.


Excellent Tracking Performance
Both axes are driven by servo motors with a gear drive designed to carry telescopes with ease. The mount supports three tracking rates: sidereal, solar, and lunar. Sidereal is the standard rate for visual observing and astrophotography. Solar and lunar modes adjust the rate to follow the sun or moon at their respective speeds.
Dual-axis tracking lets the mount correct small pointing errors during slewing and maintain accurate tracking without manual input. The RA gear is 73mm in diameter. The drive does not use spring-loaded worms.


SynScan Pro App with 42,000+ Targets
Utilizing Sky-Watcher's SynScan GoTo system, the mount can point to any of the 42,000+ objects in its database. The database spans multiple catalogs and includes stars, planets, open and globular clusters, nebulae, and galaxies. Alignment takes place through the SynScan Pro app over the mount's built-in WiFi connection. You select two or three alignment stars, center them in the eyepiece, and confirm. The mount uses those points to model the sky. Adding more alignment stars improves pointing accuracy across the field.


Polar Alignment
The EQ-AL55i Pro features a built-in illuminated polar scope for fast, easy nighttime polar alignment with no extra tools required. Adjustable from 0°–80° latitude, it’s ready for observers nearly anywhere in the world. For even greater tracking accuracy, the SynScan app also includes an advanced polar alignment routine, this method takes more time but provides much better results. It requires a multi-star alignment first for pointing accuracy, and should be done with the mount facing roughly north even if you can't see Polaris!


Robust Build for a Smaller Mount
The included steel tripod adjusts from 45 to 58 inches in height. The legs are 1.75 inches in diameter. The tripod weighs 11.5 lbs. When folded, it measures 39 inches long. It breaks down to a manageable package for transport to dark sky sites.
The mount head uses a V-style dovetail saddle. This is compatible with standard Vixen-style dovetail bars, which are used on most commercial refractors and many other optical tubes. The mount head weighs 8.2 lbs and is small enough to pack up in many suitcases or totes.


Counterweights and Balance
Two counterweights are included: a 3.9-pound (1.8 kg) weight and a 7.7-pound (3.5 kg) weight. Used together, they provide 11.6 pounds of counterbalance. Each weight slides along the 15-inch counterweight bar and locks in position.
The counterweight bar can be mounted in two positions on the mount head. This extra flexibility makes it easier to balance optical tubes of different lengths without moving the counterweights to their limits. Proper balance reduces load on the motors and helps maintain tracking accuracy.

Frequently Asked Questions
Do I need a hand controller to use this mount? No. The EQ-AL55i Pro is designed to be operated through the SynScan Pro app via built-in WiFi. You can complete alignment, select targets, and adjust tracking from a phone or tablet running iOS or Android. A SynScan hand controller is compatible with this mount but is sold separately and is not required.
Is this mount compatible with ASCOM telescope control software? Yes. According to Sky-Watcher, the EQ-AL55i Pro supports ASCOM telescope control. This makes it compatible with common astrophotography software on Windows such as Sequence Generator Pro and N.I.N.A. You can also connect it directly to a PC via the USB-C port using compatible planetarium software.
Does the 22-pound payload capacity include the counterweights? No. The 22-pound figure refers to instrument capacity only. It covers your optical tube, focuser, camera, and other equipment mounted on the saddle. The counterweights are not counted in that number. Two counterweights come with the mount: a 3.9-pound weight and a 7.7-pound weight.
What accessories are sold separately? Three accessories are not included with the mount: an optical tube assembly, a SynScan hand controller, and a pier extension. The pier extension is available separately from Sky-Watcher and is especially useful for observers in lower latitudes, where it adds clearance between the optical tube and the tripod legs.
Does this mount work in the southern hemisphere? Yes. The latitude range of 0 to 80 90 degrees covers both hemispheres. In the southern hemisphere, you will polar align on the southern celestial pole rather than Polaris. The SynScan Pro app includes alignment routines for southern hemisphere observers.
What external power supply does this mount need? The mount runs on DC power from 9 to 12.6 volts through its 2.1mm female power port. It does not have an internal battery. Common options include a 12V portable power pack designed for telescope mounts or a regulated DC supply rated for at least 3 amps. The included DC power cable connects to a standard DC source.
