iOptron SkyTracker Astrophotography Equipment

Equipped with his five senses,
man explores the universe around him
and calls the adventure Science.
--Edwin Hubble

Some dreams eventually become reality — and this one arrived in the form of the iOptron SkyTracker.

Before acquiring the SkyTracker, I was already tracking the night sky at home using a piggyback setup on my Celestron 4SE. While effective, that configuration was simply too heavy and impractical for long trips, especially when flying to remote dark-sky locations.

The iOptron SkyTracker solved that problem elegantly. It is compact, lightweight, and designed specifically for portable astrophotography. Despite its small size, it performs the same essential task — accurately following the rotation of the sky — allowing longer exposures and cleaner night-sky images.

This portability completely changed how I approach travel astrophotography. Flying to dark-sky locations now means I can capture more stars and the Milky Way in a single exposure without transporting a full telescope mount.

In practice, the SkyTracker easily handles my typical setups: Canon EOS 60Da paired with either the ultra-wide Canon EF 16–35mm f/2.8L II USM or the telephoto Canon EF 200mm f/2.8L II USM.

All photographs below were taken during the daytime and are shown for equipment demonstration purposes. They illustrate the SkyTracker with various camera and lens configurations (except the final image, which shows the SkyTracker alone).

Why a Portable Star Tracker Matters

While star trackers are often associated with wide-field astrophotography, their importance becomes even greater for deep-sky astrophotography. As focal length increases — whether using telephoto lenses or small refractors — Earth’s rotation causes stars, nebulae, and galaxies to drift rapidly across the sensor. In these cases, accurate tracking is essential to preserve fine structure and detail.

Star tracking is equally valuable for other types of astrophotography. During solar and lunar eclipses, a tracker allows the camera to follow the Sun or Moon across the sky, keeping the subject centered during long sequences or time-lapse imaging. It is also critical for photographing comets, conjunctions, and other moving objects, where precise tracking significantly improves image sharpness and framing stability.

For traveling astrophotographers, portability is critical. The iOptron SkyTracker strikes an excellent balance between accuracy, weight, and simplicity, making it ideal for airline travel and remote locations.
