- Carry-on size, tripod included
- NASA/SETI citizen-science campaigns
Cons

- Narrow field: no full Moon, no Andromeda
- 5-hour battery
- No EQ mode, no filters
What fits in the field of view
The Odyssey Pro telephoto camera frames 0.75° × 0.56° of sky. Below, its frame (gold) is drawn to scale over three popular targets.
| Object | With the Odyssey Pro |
|---|---|
| Full Moon | Just fits, no margin |
| Andromeda Galaxy (M31) | Needs a mosaic (about 6×3 frames) |
| Orion Nebula (M42) | Needs a mosaic (about 2×3 frames) |
| Pleiades (M45) | Needs a mosaic (about 3×4 frames) |
| North America Nebula | Needs a mosaic (about 4×4 frames) |
| Whirlpool Galaxy (M51) | Fits (24% of the frame width) |
| Ring Nebula (M57) | Fits, but small: about 89 px across |
| Jupiter | Fits, but small: about 48 px across |
Object sizes are approximate apparent sizes. Pixel counts use an image scale of 0.93″ per pixel. Try any combination in the field of view comparator.

How it compares
Exposure length in alt-az mode
Alt-az tracking rotates the field slowly. With this field and image scale, the frame corner smears by one pixel after about 7 seconds (target due south at 45° altitude, observer at 40° latitude). That is why smart telescopes stack many short exposures; this model has no EQ mode, so it relies on short subs and software de-rotation. See EQ mode and wedges explained.
