Looking for a Seestar S50 alternative? Then you’ve probably already gemerkt that the most popular smart telescope of recent years is no longer available for regular order. The ZWO Seestar S50 is no longer part of our regular lineup. In this article, you’ll learn what’s going on, what this means if you already own an S50, and which smart telescope is now the logical choice. The short answer: the Seestar S30 Pro and the DWARF 3 take the baton and both do more than the S50 on important points.
Why is the Seestar S50 no longer available?
The Seestar S50 was released in 2023 and set the standard for affordable smart telescopes. Since then, the market has evolved rapidly. ZWO itself released the S30 and the S30 Pro, featuring newer sensors and smarter software, and by now also the Seestar S50 Pro as a direct successor with the same 50 mm aperture. The regular supply of the original S50 has stopped.
Every now and then we still have a single copy, for example second-hand in good condition. Look there on the Seestar S50 Product Page, If there's nothing to order, then there's nothing at that moment.
Do you already have an S50? Good news
First, reassurance for current owners: your telescope won't suddenly become worthless. The Seestar app will continue to work and ZWO will support the device with updates. Accessories such as filters, bags, and tripods will remain available. Therefore, there is no reason at all to get rid of your S50; it takes the same beautiful photos today as when you bought it.
The two best alternatives in a row
The S50 had two strengths: the largest aperture in its price range (50mm) and a complete out-of-the-box package. The alternatives each take a different route. One wins on image quality and ease of use, the other on freedom and battery life.
| Seestar S30 Pro | DWARF 3 | |
|---|---|---|
| Optics | Quadruplet APO, 30mm, f/5.3 (160mm) | 35mm telephoto lens + separate wide-angle lens |
| Main sensor | Sony IMX585, 4K (8.3 MP) | Sony IMX678, 8.3 MP |
| Field of view | 4.6° (telephoto) + 63° wide-angle | Wide field of view, ideal for large objects |
| Weight | 1.65 kg, tripod included | Light and compact, tripod sold separately |
| Storage | 128 GB | 128 GB |
| Strong in | Allround: Deep sky, Sun, Milky Way mode | Large objects, long sessions, lots of control |
| Price | € 749 | Better priced than the S30 Pro |
Alternative 1: Seestar S30 Pro, the logical successor within ZWO
If you come from the S50 mindset of “set it down and enjoy,” then the ZWO Seestar S30 Pro the most logical choice. You stay within the same ecosystem: the same app, the same workflow, the same complete package including tripod, solar filter, and carrying case. The aperture is smaller than that of the S50 (30 mm compared to 50 mm), but that is offset by a lot: a modern 4K sensor that captures much more detail than the 2 MP sensor of the S50, a quadruplet APO lens, a second 4K wide-angle camera for Milky Way photography, and an internal filter wheel. In practice, you get images out of it that the S50 simply couldn't produce for most objects.
Please note the delivery time: the S30 Pro is new and popular, so it is frequently on backorder. Order on time if you want to be sure of receiving one from the next shipment.
Alternative 2: DWARF 3, more freedom and a large battery
The DWARF 3 Choose a different philosophy. Where Seestar focuses on immediate results, the DWARF 3 gives you more control over settings and a wide field of view in which large objects like the Andromeda Galaxy fit completely. The large 10,000 mAh battery allows for long nights without a power bank. A tripod is not included, but any photo tripod with a standard connection will fit.

Tight budget? Don't forget the regular S30
