The short answer
The Origin Mark II gathers about nine times the light and is the better deep-sky imager if you observe from home. The Vespera Pro 2 is the better choice if you move your telescope: 11 lb against 41.6 lb, an 11-hour battery, a wider field and a 5-year warranty, for $1,309 less.
Both are premium, fully automatic smart telescopes for people who want results without building an astrophotography rig, but they take opposite approaches. Celestron's Origin Mark II maximizes light with a 6-inch f/2.2 RASA. Vaonis's Vespera Pro 2 maximizes refinement and portability with a 50 mm apochromat and a 12.5 MP sensor. We compared the makers' specs and reviews; we have not tested them ourselves. See how we research.

Light-gathering
This is the Origin's decisive advantage. Its 152 mm aperture has about nine times the area of the Vespera's 50 mm, and at f/2.2 it builds images from 10-second frames. Space.com, testing the original Origin, got "crystal clear images of nebula and galaxies almost instantly". For faint galaxies the Origin will show more in less time.
Detail and field
The Origin's finer 1.23″ per pixel helps on small galaxies; the Vespera Pro 2 counters with a wider square field and mosaics up to 50 MP for large nebulae. Neither is a planetary instrument: reviewers of the original Origin couldn't focus on Saturn, and the Vespera's 245 mm focal length keeps planets small.
Portability and practicality
The Vespera Pro 2 is a single 5 kg unit with an 11-hour battery, a carbon-fiber tripod and a 5-year warranty. The Origin is three pieces weighing 41.6 lb together, with a "6+ hour" battery or mains power; reviewers also found its mount motors "fairly loud".
Which should you buy?
- Origin Mark II if you image from your backyard and want the deepest images any smart telescope can make. Read the review.
- Vespera Pro 2 if you'll travel to dark skies, value long battery life and warranty, or want a simpler setup.
Want deep-sky performance for less? The Dwarflab Draco offers 90 mm with guided 300 s exposures for $1,399; see best for deep sky.
