Smart telescopes: what to check before you buy

An integrated camera records the target while a motorised mount points and follows it. Some systems take a picture of the sky and match the stars to a catalogue to work out where they are pointing. The app can then display images and combine multiple exposures, a process often called stacking.

For example, the Seestar S50 manual describes automatic pointing, tracking, plate solving and live stacking. Vaonis explains how its Stellina uses star patterns to initialise. Features and setup differ by model: read the manual for the exact version you are considering.

Decide how you want to experience the sky. With a conventional visual telescope, you look through an eyepiece. A camera-based smart telescope shows a captured image on a screen, which can be useful for sharing the view and saving an image. Celestron says its Origin uses its companion app and does not use an eyepiece.

Neither approach is automatically better for everyone. If seeing the Moon or Saturn directly through glass is the part you value, try an eyepiece telescope at an astronomy club or public observing event before buying. If you prefer building and sharing images from a compact setup, compare a camera-based system. Our beginner telescope guide explains conventional telescope and mount choices.

Clouds, obstructions, wind and local light still matter. A telescope that identifies star patterns needs enough visible sky to initialise; Vaonis notes that cloud or an obstructed view can prevent Stellina from starting. Some targets will be too low, outside the system's field of view or poorly suited to its optics and camera.

Stacking can improve an image over time, but the result depends on the target, the equipment and conditions. Manufacturer images are examples, not a promise of the same result from your location. Check the Tonight forecast for available cloud and Moon context and have a safe, permitted place to set up.

Before paying, check the current manual, local retailer listing and return terms for the exact model:

1. Targets and field of view: Look for examples of the Moon, planets or deep-sky objects you want to see. A system suited to wide nebulae may show a planet as a very small image. Vaonis describes this trade-off for Stellina.
2. Phone and software: Check supported phone or tablet versions, connection method, app availability and whether the functions you want require an account or internet access.
3. Files and control: Find out whether you can save the finished image and access individual or raw frames, and which settings you can change. Capabilities vary by model.
4. Transport and power: Compare the weight and size of the whole setup, tripod, case, charging method and expected battery life. Check current local prices and included accessories rather than relying on an old comparison.
5. Support and repairs: Check the warranty in your country, return conditions, spare parts and the manufacturer's update policy. An app-dependent product also depends on continuing software support.

Never point a telescope or camera at the Sun without a suitable, properly fitted solar filter designed for the front of that specific optical system. Ordinary eclipse glasses are not a substitute for a telescope filter. Follow the manufacturer's instructions, including for any finder or secondary camera, and inspect the filter before use. If the instructions are unclear, do not attempt solar observing. See NASA's eclipse safety guidance.
