Vaonis Vespera 3 Smart Telescope - Auto-Tracking, Live Stacking, 11h Battery, 115GB Storage, Aluminium Tripod Review (2026)

What kind of telescope this is

The Vespera 3 is a smart telescope rather than a traditional eyepiece scope, meaning it captures and stacks images automatically through a phone or tablet app instead of offering a view to look through directly. It uses a 50mm aperture optical system with a 245mm focal length at f/4.9, paired with a Sony IMX585 sensor that natively captures 8.3 megapixel images at 3840 by 2160 resolution, with processed output reaching up to 24 megapixels. A refined field corrector helps keep stars sharp across the frame, and the native field of view of 2.5 by 1.4 degrees can be widened to 4.33 by 2.43 degrees using the device's built in mosaic mode for larger targets like sprawling nebulae.

Battery life and all night sessions

Vaonis rates the Vespera 3 for up to 11 hours of battery life, enough to run from dusk to dawn in many seasons without needing an external power bank, which is a meaningful convenience for observers who want to start an imaging session and walk away rather than babysitting cables. The telescope also includes an integrated hygrometer paired with automatic anti fog activation, which helps keep the optics clear through dewy nights without manual intervention. Charging and data transfer both happen over USB-C, and the faster transfer speed on this generation helps move large image files off the device more quickly once a session ends.

Storage and image handling

115GB of internal storage lets the Vespera 3 hold many observing sessions worth of raw and processed images before a user needs to offload files to a phone or computer, and the device supports up to 15 separate multi night stacking slots so a long exposure project on a faint target can be continued across several sessions rather than starting over each time. Images can be saved in JPEG, 16 bit FITS or 16 bit TIFF formats, giving more flexibility for users who want to do additional processing later compared with a device that only outputs finished JPEGs.

What is included and physical design

The complete package includes a high quality aluminium tripod, a CLS light pollution filter and a carrying backpack, so the telescope arrives ready to set up at a dark site without needing to buy a separate mount or transport case. The unit itself measures 48 by 20 by 9 centimeters and weighs 5 kilograms, making it a two hand carry rather than a truly pocketable device, though still far more portable than a traditional telescope, mount and tripod setup. Vaonis backs the Vespera 3 with a 5 year warranty, longer than the coverage offered on many competing smart telescopes.

Verdict and how it compares

The Vespera 3 ranks third among smart telescopes in this comparison, behind two ZWO Seestar S50 models that offer a larger 50mm aperture at a lower price, and just ahead of ZWO's smaller Seestar S30 Pro. Its strongest advantages are the included aluminium tripod, generous 115GB storage and long 11 hour battery life, all of which reduce the number of extra accessories a buyer needs to complete a working setup. The main tradeoff is price, since it sits above simpler all in one rivals, and like all smart telescopes it trades the direct eyepiece view that some visual observers still prefer for a screen based, fully automated imaging experience.
