Unistellar Odyssey Pro specifications
A 1.45 µm pixel size is the key sensor figure for this smart telescope, although no sensor model or megapixel count is included in its specifications. The 320 mm focal length and f/3.9 focal ratio describe the reflector's optical setup, while autofocus is included.
Optics and field
The 85 mm (3.3 in) aperture gathers more light than most of the telescopes compared, placing its light grasp ahead of most in this group.
Its 320 mm focal length works with 1.45 µm pixels to put finer detail within reach than most of the telescopes compared. This comparison uses the tighter limit between the optics' resolving power and the sampling across two pixels, rather than treating focal length alone as a measure of detail.
The maker quotes a limiting magnitude of 17.2. This is the manufacturer's stated figure for the faintness limit, not a promise of what your local sky will allow.
The field of view is 33.6 x 45 arcminutes according to the maker. Its longest side frames a narrower patch of sky than most of the telescopes compared, a consideration when choosing targets that need more room in the frame.
Mount, app and observing features
An alt-azimuth mount carries the reflector, with control through the Unistellar app for iOS and Android. The electronic eyepiece is present, and autofocus is included, so focusing is handled by the telescope rather than left entirely to manual adjustment.
Software noise and light pollution filtering in the app addresses light pollution during imaging. For your garden under bright street lighting, that processing is relevant to emission-nebula imaging, but it does not remove the effect of the surrounding sky.
The telescope has 64 GB of internal storage. That gives you space on the instrument for saved material, while the app provides the stated control route from a compatible phone or tablet.
Carrying and power
The maker quotes a telescope weight of 4 kg, excluding the 2.5 kg tripod. The carried telescope weight sits in the middle of the telescopes compared, using the telescope alone for this portability comparison. The separate tripod adds to what you need to carry from indoors to your garden.
Battery life is 5 hours according to the maker. That figure places the Odyssey Pro's battery life alongside its autofocus and app-based filtering for an ease comparison; the combined assessment leaves more to do by hand than most of the telescopes compared.
Comparison summary
- Light grasp: ahead of most of the telescopes compared (based on aperture).
- Detail: finer than most of the telescopes compared (based on the tighter of optical resolution and two-pixel sampling).
- Field: narrower than most of the telescopes compared (based on the longest side of the main camera's field).
- Portability: in the middle of the telescopes compared (based on telescope weight, with the tripod excluded).
- Ease: leaves more to do by hand than most of the telescopes compared (based on battery life and the stated hands-off features).

For first nightsFor town skies
A good match if you want autofocus, app-based light pollution filtering or an electronic eyepiece.
Less so if you want a wider field of view or a lighter complete carry with the tripod.
