Telescopes with Tracking: Auto-Tracking & GoTo Guide 2026

Quick Answer

Telescopes with tracking fall into three categories: GoTo (fully automatic — enter a target or tap on a map, and motors move the scope there and track it), PushTo (computer-assisted — the system shows which way to push, and you track manually), and motorized manual (a basic motor that tracks after you centre an object). For beginners, the Celestron StarSense Explorer series offers the easiest GoTo experience using a smartphone app. For planetary observers, the Celestron NexStar 5SE provides reliable tracking at a reasonable price.

How Telescope Tracking Works

Because the Earth rotates, everything in the night sky appears to move from east to west at about 15 degrees per hour. Without tracking, objects drift across the field of view and exit the eyepiece within seconds to minutes, depending on magnification. At 200×, Jupiter drifts out of a typical eyepiece field in about 30 seconds.

An auto-tracking telescope compensates for this motion by moving the telescope at the same rate in the opposite direction. To do this accurately, the telescope needs to know its orientation relative to Earth's axis. The process of establishing this orientation is called alignment — typically done by centering two or three bright stars in the eyepiece or using GPS and a level sensor for automatic alignment.

Most modern tracking telescopes include a hand controller or smartphone app with a database of 10,000 to 100,000+ celestial objects. You select a target (e.g., "Jupiter" or "M13"), and the telescope slews to that object and begins tracking automatically. This combination of GoTo (finding objects) and tracking (following them) is what makes computerized telescopes so popular.

GoTo vs PushTo vs Manual Tracking

Alt-Az vs Equatorial Tracking

Two different mount types provide tracking, and the choice between them depends on what you plan to do:

Alt-azimuth (alt-az) mounts move in two axes: up/down (altitude) and left/right (azimuth). Computerized alt-az mounts, like those on the NexStar SE series, track objects by continuously adjusting both axes at varying speeds. This works perfectly for visual observing and planetary imaging but causes field rotation in long-exposure astrophotography — the image slowly rotates in the frame.

Equatorial mounts are aligned with Earth's axis. They rotate only one axis (right ascension) at a constant speed to track objects, matching Earth's rotation precisely. This eliminates field rotation, making equatorial mounts essential for long-exposure deep-sky astrophotos. The trade-off is a more complex setup: you must polar align the mount with the celestial pole, a process that takes 10–20 minutes.

For visual observers, a quality alt-az GoTo mount is perfectly adequate and much simpler to set up. For astrophotography, an equatorial mount (GoTo or manual) is necessary. See our mount buying guide for more details.

Tracking Accuracy and What to Expect

The quality of tracking varies significantly between telescope models and price points. Entry-level GoTo mounts (typically found on telescopes under $500) offer adequate tracking for visual observing at low to medium magnification — you will need to nudge the scope every few minutes at 150× or higher. Mid-range mounts (NexStar SE series, Sky-Watcher AZ-GTi) track smoothly at up to 250× for extended periods, making them suitable for detailed planetary observation without constant correction. Premium mounts (Celestron Evolution, Sky-Watcher EQ6-R) achieve sub-arcsecond tracking accuracy suitable for long-exposure astrophotography.

Periodic error — a small, repeating wobble caused by imperfections in the mount's worm gear — is present in all tracking mounts under $3,000. In visual use, periodic error is barely noticeable; your eye naturally follows the small motion. In astrophotography, periodic error produces slightly elongated stars in unguided exposures longer than 30-60 seconds. An autoguider system (a secondary camera and scope that sends real-time corrections to the mount) eliminates this entirely, enabling 5-10 minute exposures.

The single most important factor in tracking accuracy is alignment quality. A GoTo mount that is poorly aligned will track poorly, regardless of its mechanical quality. Taking 10-15 minutes to carefully centre alignment stars, using a reticle eyepiece if available, dramatically improves tracking performance. Many experienced users perform a three-star alignment (which models sky distortion across the hemisphere) rather than the faster two-star alignment, and report noticeably better pointing and tracking accuracy as a result.

Adding Tracking to a Manual Telescope

You do not need to buy a new telescope to get tracking. Several options exist for adding tracking to an existing manual telescope:

• ●Equatorial platform — A motorized platform that sits under a Dobsonian base, rotating slowly to track objects. Platforms add about 30-45 minutes of tracking time before needing a reset. Popular for Dobsonian owners who want to do visual tracking or short-exposure astrophotography.
• ●Motor drive kit — Add-on motor kits are available for many equatorial mounts, providing single-axis tracking for $100-$300. The motor attaches to the RA worm gear and drives it at the sidereal rate. This is the most affordable way to add tracking to an existing mount.
• ●Star tracker camera mount — For wide-field astrophotography with a camera and lens (not a telescope), a star tracker like the Sky-Watcher Star Adventurer provides accurate tracking in a portable, affordable package. See our best star trackers guide for recommendations.
