Unistellar eQuinox 2 review: specs, price and verdict

114 mm Newtonian, 11-hour battery, limiting magnitude 18.2; manual focus and collimation.

  • 114 mmaperture
  • 0.76° × 0.57°field of view
  • 1.33″per pixel
  • 7 kgweight
  • 11 hbattery

Our verdict

More aperture than the Odyssey for less money, at the cost of weight and a little maintenance.

Best for: Backyard observers who want maximum aperture per dollar and can collimate.

Pros

  • 114 mm mirror: 5.2× the light of a 50 mm
  • 11-hour battery
  • Limiting magnitude 18.2
  • Cheapest route to 114 mm in a smart telescope

Cons

  • 7 kg, checked-baggage size
  • Manual focus (Bahtinov mask) and collimation
  • Narrow field
  • No eyepiece

What fits in the field of view

The eQuinox 2 telephoto camera frames 0.76° × 0.57° of sky. Below, its frame (gold) is drawn to scale over three popular targets.

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 10 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.
