Seestar S30 Pro vs S50 Pro vs Dwarf 3: Which to Buy

For a first smart telescope, buy the ZWO Seestar S30 Pro. It was $699 on ZWO’s US store on November 7, 2026, and the box includes a small tabletop tripod, a solar filter and a carrying case. Pay $999 for the Seestar S50 Pro if you want a bigger 50 mm lens for small, faint galaxies and a longer battery rating, though at 2.8 kg by ZWO’s figure it is the heaviest of the four.

To spend less, look at DWARFLAB’s two models. The DWARF 3 was $549 and the DWARF mini $419 on DWARFLAB’s US store on November 7, but neither comes with a tripod. The mini’s main camera makes 2-megapixel (MP) pictures, against about 8 MP on the other three.

A smart telescope is a telescope, camera and motorized mount in one box that your phone runs. You pick a target in the app, and the telescope finds it, tracks it and stacks many short exposures into one picture that builds on your phone screen; you do not look through an eyepiece.

Smart telescopes compared

The figures below are each maker’s own specs and US store prices on November 7, 2026, not one lab’s measurements. ZWO also runs separate Global and Europe stores, so prices outside the US differ.

Telescope	Maker price, Nov 7	Main lens width	Main camera	Weight	Battery (maker figure)	Tripod in the box
Seestar S30 Pro	$699	30 mm	8.3 MP	1.65 kg	About 6 hours	Yes, tabletop
Seestar S50 Pro	$999	50 mm	8.3 MP	2.8 kg	Up to 9 hours	Yes
DWARF 3	$549	35 mm	8 MP	1.35 kg	Up to 5.5 hours	No
DWARF mini	$419	30 mm	2.07 MP	840 g	4 hours	No

The main lens width (the aperture) decides how much light the telescope collects; ZWO says the S50 Pro’s 50 mm lens has “nearly three times the light-gathering area of a 30 mm aperture.” The weight is the telescope alone; ZWO lists the S50 Pro’s 2.8 kg as the main unit, and Live Science weighed it at 2.7 kg. ZWO’s battery figures come from its own laboratory: about 6 hours for the S30 Pro at 25°C, and up to 9 hours for the S50 Pro in temperatures above 25°C. DWARFLAB gives the DWARF 3’s 5.5 hours as an average for astronomy photos at room temperature.

Each one also has a second, wide-angle camera that the makers pitch for the Milky Way and wide night-sky shots. On the Seestars, that wide camera is 8.3 MP; on both DWARFs it is about 2 MP.

Seestar S30 Pro vs S50 Pro

Buy the S30 Pro if you want the easier one to carry and the lower price. It weighs 1.65 kg, has a built-in heater that keeps dew off the lens, and has 128 GB of built-in storage. Space.com’s reviewer, Jamie Carter, called it “Small and lightweight” and said it “Performs well under light-polluted skies.”

Buy the S50 Pro if you want more detail on small, faint targets and a longer battery rating. Its 260 mm focal length, against 160 mm on the S30 Pro, makes small targets look bigger, while the S30 Pro’s wider view fits more of a large target in one frame, as the comparison site Skies & Scopes explains. ZWO rates its battery at up to 9 hours and says it has a “precision drive system with near-zero backlash” for “faster, smoother tracking” in EQ mode (explained below). Live Science says this motor gives more precise tracking and better resistance to wind than the S30 Pro’s geared motor, though its test nights had little wind. The tripod, a solar filter and a protective case come in the box.

Live Science’s Jase Parnell-Brookes tested the S50 Pro and wrote that ZWO’s “own S30 Pro is $300 cheaper and bags a large amount of the same features and specifications.” The reviewer could not yet test the 9-hour battery claim, because the app update behind it had not been released during testing. The review also found the tripod “very short” and suggested a taller photo tripod, after a tree branch blew into view during a long exposure.

The S50 Pro is new: Live Science dates its release to August 25, 2026. It was not sold on Amazon when checked on November 7, so buy it from ZWO.

Buy the Overseas version of any Seestar. ZWO sells a Mainland China version that is meant for use only in mainland China, Hong Kong and Macau; it cannot be activated elsewhere, and one activated outside those regions gets no warranty or after-sales service.

Seestar or DWARF?

The DWARF 3 costs $150 less than the S30 Pro on the two makers’ US stores and has a 35 mm main lens against the S30 Pro’s 30 mm; both main cameras are about 8 MP. DWARFLAB lists it at 1,350 g with IP54 protection, which it describes as “Dust and dew resistant.” Its box holds the telescope, a magnetic solar filter, a cable, a carrying bag and a cleaning cloth, but no tripod. Add DWARFLAB’s $89 Mini Hydraulic Tripod and the total is $638, against $699 for the S30 Pro with its tripod. Space.com’s Kimberley Lane found it “Compact and portable” but listed “Time-consuming image capturing” and a connection range that “could be longer” as drawbacks.

The DWARF mini is the lightest and cheapest of the four, at 840 g and $419. Live Science’s Jamie Carter wrote that “its 2MP sensor limits image quality,” but that the pictures “look great on a phone screen.” The review lists “Tripod not included” and a “Four-hour battery life” among its drawbacks. Its box holds the telescope, a solar filter, a cable and a cleaning cloth; DWARFLAB sells a carry bag for it separately, at $39 on November 7.

Both makers say their telescopes save raw image files for editing on a computer later. The Seestars and the DWARFs use different apps, ZWO’s Seestar app and the DWARFLAB app.

City or dark sky: what reviewers found

All four have a built-in light-pollution filter that passes the colors glowing gas clouds (nebulas) give off, hydrogen-alpha and oxygen-III. ZWO, on its S30 Pro page, and DWARFLAB say the filter reduces the glow from city lights; on the S50 Pro it works on the main camera only. Milky Way pictures are different: ZWO says Milky Way imaging “requires dark-sky conditions.”

Space.com’s reviewers rate their skies on the Bortle scale, which runs in nine levels from Class 1, an “excellent dark-sky site,” to Class 9, an “inner-city sky.” Class 5 is a suburban sky and Class 6 a bright suburban sky.

Seestar S30 Pro: Space.com tested it “under suburban Bortle 6 skies” and in Bortle 2 skies, and recommends it if “You observe from light-polluted locations.”
DWARF 3: Space.com tested it from “an urban backyard close to a city in Bortle class 5” and in an International Dark Sky reserve, and wrote that “It handled light pollution reasonably well.”
DWARF mini: Live Science gave no Bortle class but says it captures star clusters, galaxies and faint nebulas “from the middle of a city.” It got “a decent image in a few minutes” of the bright Orion Nebula, while a fainter nebula needed “an hour or so.”
Seestar S50 Pro: Live Science imaged the Dumbbell Nebula over 10 minutes and 20 seconds but did not name its sky’s class.

So from a suburban backyard, and from a city in the DWARF mini’s case, these telescopes can picture bright nebulas, galaxies and star clusters if you let them collect for longer; for the Milky Way, a dark site is worth the drive.

Tripods and longer exposures

All four can run in an equatorial (EQ) mode, which offsets the Earth’s rotation so the telescope can take longer exposures: 60 seconds on the Seestars and the DWARF 3, and 90 seconds on the DWARF mini, by the makers’ figures. It adds a setup step, polar alignment, which lines the mount up with the sky’s pole (near the North Star in the Northern Hemisphere): ZWO says “Accurate polar alignment is required,” and reviewers describe in-app guides for it. The extra gear differs by model:

Seestar S30 Pro: ZWO says “Without the TH10 mount, the EQ Mode on the S30 Pro cannot be enabled.” For the S30 Pro, ZWO recommends its TH10 head plus TC20 carbon fiber tripod set, which the S30 Pro page priced at $189 on November 7, or $888 with the telescope.
Seestar S50 Pro: its tripod is already included, so ZWO recommends the TH10 head alone, $99 on November 7, “For a better EQ Mode experience,” and adds a free quick-release plate when the two are bought together.
DWARF 3 and DWARF mini: DWARFLAB’s Mini Hydraulic Tripod, “designed for the DWARF series,” “Supports equatorial mount mode,” and was $89 on its US store on November 7. Live Science says the mini’s EQ mode needs an equatorial wedge, a head that tilts the telescope, and names DWARFLAB’s Mini Hydraulic Tripod Head for it.

Mind the screw. The Seestar S30 Pro and S50 Pro use a 3/8-16 tripod thread, and the DWARF 3 and DWARF mini a 1/4-inch one. Live Science warns that the S50 Pro “won’t fit the 1/4-inch thread of your standard mirrorless camera,” so a camera tripod’s head may need to come off first.

Not picked, and why

The older Seestar S30 and S50: both showed “Sold out” on ZWO’s US store on November 7, 2026.
The Seestar S30 Plus: ZWO’s store asked shoppers to “Get Ready for the New Seestar S30 Plus!” and sign up for news, with no price listed on November 7.
The DWARFLAB Draco: a larger 90 mm smart telescope, listed on November 7 as a pre-order at $1,599 for its SHO Edition and “estimated to ship within three months of your order date,” with the $1,399 Standard Edition sold out. So it may not arrive in time for a December gift.

Buying one as a gift

Check the return window before you wrap it. ZWO’s policy allows a return “within 30 days of delivery”; an opened item in like-new condition carries a 10% restocking fee, and the buyer pays the return shipping unless they bought ZWO’s optional Free Returns at checkout. DWARFLAB takes items back “in new (fully resellable) condition within 30 days of receipt for a refund, excluding shipping fees,” with a restocking fee for anything not in new condition, and a “mandatory 4% fee” on any return or cancellation; returns need its approval first. Outside the EU, UK and US, DWARFLAB does not accept returns “without valid reasons.” So a telescope delivered in mid-November can be past both windows by the time it is opened in late December.

ZWO’s return policy “applies only to products purchased through official Seestar channels,” and tells buyers from “a third-party platform or an authorized reseller” to contact the original seller. On Amazon on November 7, the S30 Pro listing linked here was sold by “ZWO STORE,” the storefront ZWO links from its where-to-buy page, and the DWARF 3 and DWARF mini listings by “DWARF LAB,” all shipped by Amazon. This page did not check Amazon’s own return terms, so look at the return window on the listing before buying a gift.

Both makers give two years of warranty: ZWO on a Seestar’s main body and camera (one year on the battery) bought “through official Seestar channels,” and DWARFLAB on the DWARF 3 and DWARF mini. DWARFLAB’s warranty is valid only for the original purchaser with proof of purchase from its “official or authorized stores” and is “non-transferable,” so keep the receipt with a gift.

This page compares the makers’ own spec sheets and prices and what named reviewers reported; it is not a hands-on test. For other gift ideas, see the tech buying guides.

Smart telescope questions

Is a Seestar worth it?

For galaxies and nebulas from a backyard with little setup, Space.com’s S30 Pro review makes the case, calling it “an accessible and portable entry point into deep-sky imaging.” Space.com recommends the S30 Pro if “You want an easy, automated entry into astrophotography,” and not if you want “full manual control over imaging” or are “primarily interested in planetary observation.” It also says the S30 Pro, as an upgrade on the older S30, “may or may not be worth the money, depending on your needs.”

Should I buy the Seestar S30 Pro or the S50 Pro?

The S30 Pro, at $699 on ZWO’s US store on November 7, 2026, unless you want the S50 Pro’s 50 mm lens, 260 mm focal length and up-to-9-hour battery for $999. The S30 Pro is lighter, at 1.65 kg against 2.8 kg.

Is a Seestar or a DWARF better?

The DWARF 3 ($549) and DWARF mini ($419) cost less than either Seestar Pro, but neither includes a tripod, and the mini’s main camera is 2 MP. Both Seestar Pros come with a tripod and an 8.3 MP main camera.

Can a smart telescope see planets?

Only small. Space.com found planets on the S30 Pro “appearing small and lacking fine detail,” though the moon “looked fabulous,” and Live Science called the DWARF mini’s planetary images “disappointing.” Space.com called the DWARF 3 “more of a wide-field instrument” for planets.

Does a smart telescope work in a city?

For bright nebulas, galaxies and clusters, in bright suburban skies at least: Space.com tested the S30 Pro “under suburban Bortle 6 skies,” and Live Science says the DWARF mini captures faint nebulas “from the middle of a city.” For the Milky Way, ZWO says you need “dark-sky conditions.”
