iOptron SkyGuider Pro

A pocketable star tracker, a tiny motorized platform your camera rides on, with nothing to look through. It slowly turns to cancel the Earth's rotation so your stars stay sharp in long exposures, and an included counterweight bar lets it carry a bit more than most trackers: a DSLR or a small refractor. iOptron's main rival to the Star Adventurer.

01What it's good at

What it's best at — and the trade-offs.

Tracks a ~5 kg payload, more than most trackers, thanks to the included counterweight bar that balances the load
Best at
✓Tracks a ~5 kg payload, more than most trackers, thanks to the included counterweight bar that balances the load
✓Barely over a kilogram, fits in a camera bag for travel and Milky Way trips
✓Built-in polar scope (iPolar-ready) for the quick one-time alignment on Polaris that tracking needs
Trade-offs
!No GoTo, you find and frame targets by hand (a phone sky-map helps); the tracker only holds the shot steady once you're on it
!Practical payload favours a camera + lens or a very small refractor, not a full telescope
!Long exposures need careful balance and modest focal lengths, it tracks but doesn't self-correct
02In plain English

The numbers, in plain English.

5kg payload
Payload
5 kg with counterweight
Five kilograms sounds generous for a tracker, and it is, but it assumes the supplied counterweight bar is in use. A camera and a fast telephoto, or a small 60 to 72 mm refractor with a light camera, is the realistic working load.
Head weight
1.0 kg
One kilogram means the tracker itself is the least of your luggage; a sturdy photo tripod and ball head weigh more. This is what makes it a genuine travel and dark-sky-trip device rather than a second observatory.
Tracking
Single axis, no GoTo
It turns one axis at sky speed to cancel the Earth's rotation, and nothing more. You aim it by hand and you find targets yourself, so a phone star chart is part of the workflow.
Polar alignment
Optical polar scope
Accuracy depends entirely on how well you align to the celestial pole, and there is no electronic assistance. A careful alignment gives clean two to four minute exposures at short focal lengths; a rushed one shows as trailed stars.
Exposure ceiling
Minutes, not tens of minutes
Unguided and at wide focal lengths this is enough for the large nebulae and Milky Way fields most people buy a tracker for. Longer focal lengths or longer subs need guiding and a heavier mount.

Editor’s Take

Like the Star Adventurer, the SkyGuider Pro is a star tracker, a small motor on a wedge your camera bolts to, with no eyepiece and nothing to look through. Its one job is to cancel the Earth's rotation: sight its axis on Polaris through the built-in polar scope (a two-minute setup), and it then turns at exactly the sky's speed, so a two-minute exposure comes out with pinpoint stars instead of trails. The included counterweight bar is what sets it apart from a bare tracker, balancing the load lets it steady a slightly heavier camera or a small refractor. "No GoTo" means it won't hunt down targets; you frame the shot yourself. It's where a lot of imagers start, cheap, tiny, and capable of genuinely stunning Milky Way and wide-field nebula shots, and it isn't trying to do long-focal-length deep-sky, which is exactly the right call at this size.
