Sky-Watcher Star Adventurer 2i Pro Pack

A star tracker, a camera-bag-sized motorized platform your camera rides on, not a telescope you look through. It slowly turns to cancel the Earth's rotation, so your stars stay pin-sharp through the long exposures astrophotography needs. This is the WiFi-app 2i in the Pro Pack (counterweight and L-bracket included), the most popular, best-supported first tracker you can buy.

Best at
✓Keeps stars sharp in long exposures: it turns at exactly the Earth's rotation rate, so you can shoot minutes-long frames with no star trails, the entire reason a tracker exists
✓Carries ~5 kg with the included counterweight, a DSLR/mirrorless + lens, or a small refractor, so you can start with the camera you already own
✓A built-in illuminated polar scope makes the one-time alignment on Polaris quick, and the SynScan phone app (WiFi) sets the tracking mode and timing
✓The largest tracker ecosystem anywhere: brackets, cases, step-by-step tutorials and community answers for almost any camera or question
Trade-offs
!No GoTo, it won't find or point at targets for you. You aim the camera by hand (a phone sky-map helps you locate things); the tracker's only job is to hold the shot steady once you're on it
!Built for a camera + lens or a very small scope, not big telescopes, and past ~2–4 minute exposures, careful polar alignment and good balance start to matter
!It tracks but doesn't auto-guide or self-correct, so framing and alignment are on you, that's the beginner learning curve
!Pro Pack contents vary by region, confirm the counterweight and L-bracket are actually included
02In plain English

The numbers, in plain English.

5kg payload
Payload
5 kg with counterweight
Five kilograms assumes the counterweight bar in the Pro Pack is fitted. A camera with a telephoto lens, or a small 60 to 72 mm refractor with a light camera, is the sensible working load; anything heavier trails.
Head weight
1.0 kg
The tracker weighs about 2.4 lb, so the tripod and ball head are the bulk of what you carry. It fits in a camera bag, which is the whole point of a tracker.
Tracking
Single axis, no GoTo
It cancels the Earth's rotation on one axis and does nothing else. You point it yourself, which for wide-field Milky Way and large-nebula work is entirely adequate and keeps the price low.
Polar alignment
Illuminated polar scope
Image quality is set almost entirely by alignment accuracy. A careful few minutes with the polar scope gives clean multi-minute exposures at short focal lengths, and a rushed alignment shows immediately as elongated stars.
Power
Internal AA batteries or USB
It runs from its own batteries or a USB power bank, so there is no 12 V supply to carry. That independence is what makes it practical on a mountainside or in hand luggage.

Buy it if you

✓Milky Way, nightscape, and wide-field photographers who already own a camera and a lens

Look elsewhere if you
!Anyone who wants the mount to find and slew to objects for them, that's a GoTo mount, not a tracker
!People chasing small, distant galaxies at long focal lengths, a tracker can't frame or guide those
!Visual observers who want to look through an eyepiece, this holds a camera; there's nothing to look through

Editor’s Take

A star tracker is a small, motorized platform your camera rides on, not a telescope you look through. It turns at exactly the sky's speed, so long exposures come out with pinpoint stars instead of trails. Setup is a quick couple of minutes: you sight the built-in polar scope on Polaris to line up its axis, then start tracking from the SynScan phone app. No GoTo means it will not find targets for you, so you frame the shot yourself while the tracker holds it rock-steady. That simplicity is exactly why more astrophotographers start here than anywhere else.

Milky Way Tracker

Featured

The simplest way into tracked astrophotography. A Star Adventurer 2i quietly follows the sky so your exposures stay sharp, while the RedCat 51 frames constellations, the Milky Way core and big nebula regions edge to edge. No laptop, no guiding, no dedicated astro camera — you bring the DSLR or mirrorless body you already shoot with, level it, point it, and shoot.
