  • The telescope specifications are higher, with 3.3 inch aperture, versus 2 inch inch for the Vespera Pro, 320 mm focal length versus 250 mm, and f/3.7 focal ratio versus f/5.

Vaonis Vespera Pro vs Unistellar Odyssey Pro: Verdict

These are two top-of-the-range smart telescopes that are brand new in 2024.

I think that if you are weighing up these two models then your decision should really come down to how much you would value the addition of the eyepiece on the Odyssey Pro. If this is a feature you think you’d want, and have the additional budget, then this is the model for you.

On the other hand, if you do not think you would get that much from the eyepiece then it would make sense to opt for the Vespera Pro, as they are a very close match otherwise.
