Celestron Origin vs Unistellar Odyssey Pro
Two premium smart telescopes priced within a few hundred dollars at list, built for different nights. We compare the current Origin Mark II; the first-generation Origin uses the same optics.
Short answer
For images, the Origin Mark II wins clearly. For portability, sharing and an eyepiece view, the Odyssey Pro. If you want Odyssey optics without the eyepiece, the plain Odyssey costs $2,000 less at list.
Key differences
- Light: 152 mm at f/2.2 vs 85 mm at f/3.9. Allowing for both central obstructions, the Origin collects about 2.9× more light, and its faster focal ratio fills each patch of sensor about 3× faster.
- Field: 1.32° × 0.75° vs 0.75° × 0.56°. The Origin frames the full Moon and the Orion Nebula; the Odyssey Pro cannot.
- Detail: the Odyssey Pro samples 0.93″/px vs 1.23″/px, so planets look slightly bigger, but seeing usually limits both.
- Weight: 18.9 kg in three pieces vs 4 kg plus a 2.5 kg tripod. The Odyssey Pro fits carry-on luggage.
- Eyepiece: only the Odyssey Pro (Nikon-developed digital eyepiece).

Highlighted cells are better on that line (price, focal ratio, image scale and weight: lower is better). Field of view is compared by area; whether wider is better depends on your targets.
