Sky-Watcher Star Adventurer GTi (S20590) review

Sky-Watcher's Star Adventurer GTi head kit: a full GoTo equatorial tracker with an 11 lb payload, built-in illuminated polar scope, Wi-Fi, USB and autoguider ports, SNAP shutter control and a dual-position counterweight.

A tracker that also finds

The Star Adventurer GTi is Sky-Watcher’s small equatorial tracker with full GoTo added. It aligns on the pole through a built-in illuminated polar scope, then finds and tracks targets from the SynScan Pro app over Wi-Fi, or from an optional SynScan hand controller.

Eleven pounds

The short feature bullets give no payload, but the description does: 11 lb. That covers a camera with a telephoto lens, a small astrograph with an astro camera, or a small Maksutov.

Ports

USB, an autoguider port, SNAP shutter control for a DSLR, and lunar, solar and sidereal tracking rates. The autoguider port is the feature that lets long exposures stay sharp.

In the head kit

The GTi head, a counterweight and counterweight bar, and a dual-position counterweight arrangement for use at low latitudes. No tripod, and no camera dovetail; the listing says so.

What observers ask about this one

What can it carry?

Sky-Watcher's description gives 11 lb: a DSLR or mirrorless camera with a wide-angle or telephoto lens, a small astrograph with a dedicated camera, or a small Maksutov such as the SkyMax series.

What is the autoguider port for?

A small guide camera on a guide scope watches a star and sends corrections to the mount through that port, which allows longer exposures with round stars.

What else do I need?

A sturdy tripod (this is the head kit) and a dovetail plate for the camera, which the listing says is not included.
