Sky-Watcher Virtuoso GTi 150P

The best smartphone-controlled tabletop scope under $700, pairing real 6-inch light-gathering with WiFi GoTo that finds what you could never star-hop to in the city, as long as you have a sturdy table and stick to visual, not imaging.

What it's built forOpen these in the simulator →

This telescope was built to gather light.

150 mm of aperture pulls in the faint light that galaxies and clusters live or die on. Point it up under a dark sky and objects that are rumors in smaller scopes resolve into real structure.

Sweet spot 110–190×Rewards dark skies
The view people remember

Andromeda, wider than the Moon.

A vast soft oval with a blazing core — two and a half million light-years of galaxy, spilling well past the field of view under a genuinely dark sky.

Best at
✓150mm of aperture pulls in 4x more light than the 76mm tabletops most beginners get stuck with, galaxies and nebulae become real targets, not faint smudges.
✓Built-in WiFi means no separate hand controller; the SynScan Pro app on iOS or Android handles alignment and slewing.
✓Freedom-Find dual-encoder design lets you push the scope manually without losing alignment, a feature usually reserved for premium mounts.
✓f/5 focal ratio gives a wide, immersive view of large DSOs like the Pleiades and Andromeda with a low-power eyepiece.
✓Collapsible tube reduces transport length by about a third, making it genuinely apartment-friendly.
Trade-offs
!Requires a sturdy, level table or pier, set it on a wobbly camping table and the GoTo accuracy collapses.
!8 AA batteries drain quickly in cold weather; most owners end up running it from a USB power bank.
!Stock 10mm and 25mm eyepieces are usable but are the first thing serious users replace.
!Alt-az mount means stars rotate in the field over long observations, fine for visual, disqualifying for deep-sky imaging.
!The single-arm fork can show vibration at high magnification until the table and scope settle.
02In plain English

What These Numbers Mean

150mm · f/5 · 750mm FL · Tabletop alt-azimuth GoTo (WiFi, SynScan app)
Aperture
150 mm (6 inch)
Six inches gathers about 460 times the light of your eye, which covers the entire Messier catalogue from a decent site and shows good lunar and planetary detail. That is a lot of aperture on a motorised tabletop mount.
Focal length
750 mm
Short enough for wide, comfortable low-power views and long enough to reach 150x with a 5 mm eyepiece. A practical range for a scope aimed at both beginners and casual observers.
Focal ratio
f/5
Fast optics reach wide, low-power fields easily, but they show the limits of cheap eyepieces at the edge and reveal collimation errors quickly. One good wide-field eyepiece transforms the experience.
Optical design
Collapsible tabletop Newtonian
The tube slides down for storage, so a six-inch reflector fits in a cupboard. The open section benefits from a shroud against dew and stray light, and collimation should be checked after transport.
Weight
8.5 kg
About 19 lb complete, carried outside in one trip and set on a table or sturdy box. Portability plus GoTo is an unusual combination at this price.
Mount
WiFi alt-azimuth GoTo (SynScan app)
Motorised on both axes and driven from your phone, so it finds and tracks objects without a hand controller. You can also push the tube by hand and the mount keeps its position, which is a genuinely useful hybrid of manual and GoTo.

04Who it's for

An honest fit check.

Beginners who want GoTo convenience without dropping $1,500+ on a full computerized mount.
Buy it if you
✓Beginners who want GoTo convenience without dropping $1,500+ on a full computerized mount.
✓Apartment and balcony observers who need a scope they can carry out one-handed and set up on a patio table.
✓Light-polluted city users who can't star-hop and need the SynScan app to actually find DSOs.
✓Families and casual users who want a real telescope that the whole household can operate from a phone.
Look elsewhere if you
!Anyone planning serious astrophotography, the alt-az tracking introduces field rotation and the mount isn't built for long exposures.
!Backyard observers with a dark site who'd get more aperture-per-dollar from a manual 8-inch Dobsonian.
!Travelers without a flat, stable table at the destination, this is not a tripod-ready scope.
!Purists who don't want batteries or apps standing between them and the eyepiece.

Editor’s Take

The Virtuoso GTi 150P is a tabletop Dobsonian with GoTo built in. The Dobsonian part is a 150 mm (6-inch) mirror in a short tube on a compact base that sits on any table; the GTi part adds motors and WiFi, so a free phone app finds and tracks objects for you (real motorised GoTo). Six inches is enough for detailed Moon and planets and the brighter galaxies and clusters, and because it is alt-az and app-controlled there is almost nothing to learn: set it down, let it align, tap a target. It removes both the "where is it?" and the "how do I mount this?" problems.

For a different goal, start here.

3 alternatives, each mapped to the goal it wins at
Cheaper

Sky-Watcher Heritage 150P (manual)

Same 150mm optics without the GoTo, saves about $250 if you're willing to star-hop and don't need tracking.

→
Different approach

Celestron StarSense Explorer DX 130AZ

Uses your phone's camera to plate-solve and guide you manually, no motors, less to break, but smaller aperture.

→
Smaller sibling

Sky-Watcher Virtuoso GTi 130P

The 130mm version is lighter and cheaper but gives up about a quarter of the light-gathering, worth it only if portability is paramount.
