Seestar S80: Cooling, Autoguiding and a Higher Price, What ZWO’s CEO Revealed

Cover image: unofficial concept illustration, not an actual ZWO product.

An 80 mm Seestar, the Seestar S80, is coming, and the news comes from ZWO founder and CEO Sam Wen himself, speaking on camera. Cooling and autoguiding are, in his words, "perhaps all planned". The price will be higher than the rivals already on the market. That is all that has been confirmed: there is still no announcement, no spec sheet, no price and no release date. Our take: if you are about to buy an S50 Pro, don't put it on hold. The S80 is shaping up to be a different, more expensive class of instrument.

Where this comes from

The information comes from an interview with Sam Wen by Linea of the Lineastro channel, recorded at the 8th Yangtze River Delta Star Party in Anji, China, in November 2026 (watch the interview). Wen answered about ten questions on the whole Seestar line, from the 30 mm models to the 80 mm. He also talked about the future of smart telescopes.

A note on wording: the Lineastro English channel states that many of its English voice tracks are translated from Chinese originals, so the quotes below may be translations. The overall meaning is clear, but individual words such as "perhaps" or "definitely" shouldn't be over-interpreted.

It is the closest thing to an official statement about the S80 so far. ZWO has not published any written announcement, product page or teaser.

What Sam Wen said about the 80 mm Seestar

1. It has to be a real leap, not a bigger S50 Pro

Wen made it clear that the 80 mm has to make users feel a major breakthrough over the 50 mm. If it ended up producing images much like the S50 Pro's, he said, it would not be worth launching. He expects "a leap in certain areas".

"Our 80-millimeter model must first make users feel it's a major breakthrough over 50 millimeters."

— Sam Wen, ZWO founder & CEO

That rules out a simple scaled-up S50 Pro. The leap, if it comes, will come from new subsystems rather than from aperture alone.

2. Cooling and autoguiding: "perhaps all planned"

When asked whether the leap meant guiding and cooling, Wen answered: "Yes, perhaps all planned." It is a hedged answer, but it points the same way as the app code leaks described below. A Chinese-language summary of the same interview, posted on Weibo, put it even more directly: the S80 "is on its way" and will have cooling and guiding.

Both features matter for deep-sky imaging. A cooled sensor keeps thermal noise down on long sessions, especially on warm nights. A dedicated guiding system corrects tracking errors while each frame is being exposed, which opens the door to longer exposures with fewer rejected frames.

3. Visual observing: considered, not decided

Asked whether the 80 mm could support visual observing, Wen said it is "something we have considered", but that it needs testing before a decision. The real dilemma is direct optical viewing versus an electronic eyepiece. Wen has tried Apple's Vision Pro and felt it "still feels different from reality". He worries that an electronic view that is "just like looking at a picture" may add little.

Reading between the lines, if ZWO does add visual observing, it seems to lean toward a true optical path rather than a screen. Nothing has been decided, though, and Wen said it would take considerable R&D and some trade-offs. He has also opened the question to ZWO's community Q&A, so user feedback could shape the outcome.

4. Price: "Ours will definitely cost more"

Wen said the 80 mm "would certainly be expensive". He pointed to the optics, the sensor, the cooling and the guiding: "the whole system adds up". Asked whether ZWO would compete directly with rivals already on the market, he answered: "Ours will definitely cost more." The Weibo summary says "slightly more" than the competitor's 90 mm model, but that nuance does not appear in the English version.

The 90 mm competitor is almost certainly the DwarfLab Draco, listed at $1,399 (Standard) and $1,599 (SHO). That makes an S80 below roughly $1,500 unlikely. This is our inference, not a ZWO figure, and the final price could land well above that.

What the Seestar app code reveals

Before the interview, the S80 had already surfaced in software:

• Android app teardown. On the Cloudy Nights forum, a user who decompiled the Seestar app reported an S80 model built on a Rockchip RK3576 processor, with a dedicated camera-cooling module (TEC, fan and anti-dew heater). He was less certain about autoguiding. The same thread had correctly anticipated the S30 Plus.
• Firmware 3.3.2. Developers of the open-source seestar_alp project noted that the firmware package includes a build targeting "S30 Pro/S50 Pro/S30 Plus/S80".

Treat leaks for what they are: application code can reference prototypes or configurations that never ship. The name itself has changed before, too. In 2025, an 80 mm-class model was being discussed as an "S70".

Why autoguiding probably means dedicated guide optics

One answer in the interview, about the S50 Pro, hints at how the S80 might handle guiding. A viewer had suggested using the S50 Pro's wide-angle camera as a guide camera. Wen said it is possible but not stable enough. The wide-angle camera is about 35 mm equivalent, while the telephoto is over 800 mm equivalent (ZWO lists 880 mm). Guiding a field more than twenty times narrower with such a short focal length is not precise enough, so ZWO did not pursue it.

If autoguiding comes to the S80, it will therefore most likely rely on a guiding solution designed for the job, as competitors have done, rather than on the existing wide-angle camera. This is our reasoning, not a ZWO statement.

The competition ZWO is answering

Wen explicitly referred to a competitor's 90 mm scope and to another smart telescope with visual observing. Here is where the S80 would land in today's line-up. These are US list prices, and specifications are from the manufacturers.

Prices and availability as of mid-November 2026, and they change often. The Draco is still in pre-order, with no independent reviews yet. The ORBIS was shown as a prototype in October 2026 and is expected in 2027. The Vaonis Atlas is due to ship in March 2027.

The table shows that until September 2026, there was a jump from the S50 Pro at $999 straight to $4,000+ instruments. The Draco opened a new $1,400–1,600 bracket with "serious-rig" features such as guiding and cooling. That is where, or just above where, the S80 is most likely to sit. ZWO's edge will probably be its app and ecosystem rather than the spec sheet alone.

Other takeaways from the interview

The interview also had several useful answers for current Seestar owners:

• No 90–120 s exposures on the S50 Pro for now. Wen explained that at 60 s the sky background already exceeds the sensor's read noise in most conditions. Longer exposures are possible, but stacking success could drop to 70–80%, with inconsistent results from one site to another. ZWO prefers predictable results.
• The S50 Pro sensor story. ZWO originally planned to use Sony's IMX585, but Sony could not supply the required volumes. Wen personally field-tested two alternative sensors against the 585, and the results were "quite close". The chosen sensor is the OmniVision OS08B10.
• S30 Plus positioning. In Wen's words, the S30 Pro is a dual-camera 4K system and the S30 Plus a dual-camera 2K. Unlike the original S30, the Plus can stack wide-angle frames, for example for the Milky Way. His advice: buy the newer model rather than a used S30. We covered the S30 Plus in detail here.
• Smart telescopes won't replace modular rigs. According to Wen, integrated products still can't match the flexibility or performance of a modular setup. ZWO will keep both lines, with the long-term goal of making modular rigs as easy to control as a Seestar.
• Next frontier: interaction. Wen sees the next step in an AI assistant built into the telescope, which you could ask to polar-align or to suggest tonight's targets. This is a vision, not an announced product.

Should you wait for the Seestar S80?

The S80 has no date and is likely to sit in a different price bracket. Waiting only makes sense if you are after the specific capabilities it promises. Otherwise, the S50 Pro remains the reference for ease of use and value. We went through it in our S50 Pro announcement article.

What it could mean for accessories

A larger, cooled and possibly heavier S80 would change some practical needs. These include a sturdier tripod and head, a properly sized equatorial wedge, and external power, since TEC cooling draws extra current. Dew control and stray-light shielding on a larger front aperture will also need a fresh look. We won't promise compatibility with anything until real specifications and units exist. Once they do, we will evaluate the S80 the way we evaluate every Seestar: on the actual hardware.
