Product information "ZWO Seestar Smart Telescope S50 Pro AP50/260"
With its 50 mm aperture, superb optics and four observation modes, the ZWO Seestar Smart Telescope S50 Pro AP50/260 is the ideal companion for anyone keen to explore the night sky. Packed with thoughtful upgrades, it's the most capable Seestar yet – small enough to take anywhere, but built with the kind of technology usually reserved for serious professional setups.
Three steps to your first shot of space
Set up the tripod, open the app, tap your target – and that's it. The S50 Pro takes care of alignment, focusing and tracking on its own, so within minutes you're already looking at stunning shots of the night sky right there on your screen. What used to be a fiddly, technical hobby is now something anyone can pick up, no experience needed.
Four modes, one telescope
Whether you're after deep-sky objects or dramatic landscapes, the four shooting modes – Stargazing, Milky Way, Solar System and Scenery – have you covered. Capture stunning celestial objects with the same ease as birds or distant scenery, opening up all kinds of possibilities well beyond the night sky. Pop on the included solar filter and you can even get striking shots and videos of sunspots, solar transits and eclipses.
50 mm aperture: more light, more detail
The 50 mm aperture gathers nearly three times as much light as a 30 mm lens, giving you noticeably sharper optical resolution. Paired with a powerful 8.3 MP sensor, the S50 Pro picks out the finest details in distant objects – from subtle features in deep-sky targets to the rugged texture of the Moon's surface. And thanks to its folded optical design, all this power comes in a body that's still compact and easy to carry.
4K dual camera: two lenses working together
The S50 Pro's telephoto and wide-angle cameras work in tandem, both shooting in 4K UHD. The telephoto lens picks out fine detail with a 2.8° field of view, while the wide-angle camera takes in the whole star field at 63° – giving you the best of both worlds, from precise deep-sky shots to sweeping wide-angle astro images.
Mosaic stitching for the bigger picture
The mosaic feature stitches together several telephoto shots into one seamless image, so you get a wider view without losing detail – all in a single high-resolution photo of up to 8K. Perfect for capturing large objects in full.
4-element apochromatic lens
A four-element apo lens with ED (Extra-low Dispersion) glass keeps chromatic aberration to a minimum, giving you sharp, round stars against a clean, neutral black sky – for images that are crisp, clear and beautifully balanced.
Triple filter system
The astronomical light-pollution filter cuts through interference from moonlight and city lights, the dark-frame filter removes noise from long exposures, and the IR-cut filter blocks infrared interference for cleaner shots overall.
A huge object database, all at your fingertips
Pick a target from a database of over 80,000 deep-sky objects and more than 600,000 stars, then just hit GOTO. The S50 Pro finds, tracks and photographs it automatically, handing you a polished cosmic image in just a few minutes.
Two worlds, one sharp image
The S50 Pro automatically picks out the foreground landscape, locks it in place, and processes it separately from the sky above – and you can set how long this landscape lock lasts. While the stars stay pin-sharp thanks to precise tracking, the landscape below remains crisp and natural, giving you beautifully composed astro-landscape shots.
Milky Way shots and star trails, made easy
Capturing our own galaxy has never been simpler with this smart telescope. Star trails are just as effortless too – the S50 Pro turns long-exposure sequences into dynamic videos that beautifully capture the sky's movement overnight.
Editing made simple
Get a finished image in seconds, or dive in and fine-tune it yourself. Star reduction, star removal, cropping, brightness, contrast, noise reduction, saturation and more are all built in, so you can bring out the best in every shot in just a few taps.
Plan mode: let it run all night
Set up a full shooting plan in the app in just a few taps, then leave it to work through the night. The S50 Pro will automatically move between targets, capturing several celestial objects in a single session with no input needed from you.
Built to go the distance
A bigger 10,000 mAh battery means up to 9 hours of stargazing per charge – plenty of time to make the most of a clear night.
Open interfaces for the more advanced astronomer
The S50 Pro supports the open ASCOM Alpaca protocol, so it plays nicely with third-party astronomy software like N.I.N.A. – great for automated routines and more advanced imaging workflows. With optional accessories, you can even switch to equatorial mode, which compensates for the Earth's rotation and allows for longer exposures.

- Check the solar filter before every solar observation and ensure that it is not damaged. Hold it against a strong light source to detect any possible cracks and/or holes. Do not use the telescope for solar observation, even if the solar filter is only slightly damaged. In this case, contact the manufacturer for the appropriate replacement parts.
- Always use the included solar filter when observing the sun. Make sure it is correctly attached to the telescope according to the instructions. The solar filter is intended for use only with this telescope.
- Never look at the sun through an eyepiece/telescope without an approved protective filter. A moon filter must never be used for solar observation. The moon filter is suitable only for observing the moon. The solar filter must be mounted in front of the telescope aperture, not at the eyepiece. Otherwise, the light beam concentrated by the optics will immediately destroy the filter film, resulting in severe eye damage and potentially complete blindness.
- Check that the solar filter is securely fitted before each solar observation. Accidental detachment from the objective opening can lead to immediate and permanent eye damage and blindness.
- If the solar filter cannot be securely attached to the tube, improve the fit by placing several self-adhesive felt strips or similar material between the solar filter and the objective opening. Never use the solar filter if it cannot be properly mounted on the telescope. In such a case, always contact our customer service first.
- Be extremely cautious when observing the sun. Even a brief look through unprotected optics will immediately cause severe eye damage, potentially leading to complete blindness.
- Children must not look at the sun through the telescope, even with the filter correctly installed. Never leave children unsupervised.
- Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without taking the necessary precautions and lose their eyesight.
- Do not observe the sun after eye surgery or if you have other eye conditions without prior medical consultation.
- Wrinkles/creases in the film are normal and do not indicate a product defect.
- Do not expose the device to high temperatures.
- BATTERY WARNINGS AND SAFETY Safe handling and use of batteries and rechargeable batteries. Read and follow these instructions before using the battery or rechargeable battery. To the extent permitted by law, failure to comply with these warnings and instructions may result in damage to your product no longer being covered by the warranty. In this document, the term "batteries" also includes rechargeable batteries. Follow these instructions to ensure optimal safety and performance: DO NOT use counterfeit batteries in products. Only use the supplied batteries. Use the battery ONLY for its intended purpose. Keep batteries out of the reach of children and pets. DO NOT use batteries whose casing appears damaged, swollen or modified. Do not use batteries that are leaking, emitting an odour, swollen or melted, or that show dents, rust, cracks or scratches. The battery must NOT be disassembled, crushed, punctured, shredded or otherwise tampered with. The battery must NOT be exposed to liquids. Liquid may enter the battery circuitry, causing corrosion and compromising battery safety. A wet or damp battery must NOT be dried using a device or heat source, such as a hairdryer or microwave. The device or battery must NOT be placed near a heat source or in direct sunlight. High temperatures can cause the battery to swell, leak or malfunction. Examples include placing it on or near a radiator, hob, kitchen appliance, iron or fireplace, or inside a vehicle or next to a window in direct sunlight. The battery must NOT come into contact with metal objects. If metal objects such as jewellery remain in contact with the battery terminals for an extended period, the battery may become very hot or catch fire. The battery must NOT be stored together with hazardous or flammable materials. Store the battery in a cool, dry and well-ventilated environment. The battery must NOT be inserted incorrectly when charging. MAKE SURE that the battery compartment is empty, dry and free of dirt before inserting the battery. The battery must NOT be charged in direct sunlight or at extreme temperatures. The battery must be charged at room temperature, which is typically between 20 °C and 26 °C (68 °F-79 °F). Charging may be temporarily disabled if the battery temperature exceeds 60 °C (140 °F). If the battery is hot but its temperature is below 60 °C (140 °F), it will still charge, but more slowly than usual. Avoid dropping the battery or the product with the battery inside. If dropped onto a hard surface, the battery or product may be damaged. If you suspect that the battery may be damaged, replace it. NEVER leave the device connected to the power supply for more than 24 hours for charging. Allow the battery to discharge and then recharge it. Leaving the device connected to a charger without allowing the battery to discharge may affect battery performance or damage the battery or device. If a battery provides a significantly shorter runtime than when it was purchased, it has reached the end of its reasonable service life. We therefore recommend replacing it. For optimal results and performance, batteries should be replaced after 12 months or earlier depending on usage. Follow local regulations for the disposal of used batteries. DO NOT throw the battery into fire or water.
