Aperture
50 mm
Two inches of aperture, so results come from stacking many frames rather than raw light grasp. Large bright nebulae, clusters and the Andromeda Galaxy work well; small faint targets are beyond it.
Focal length
250 mm
A wide field that suits exactly the large showpiece objects most people want their first images of. Its mosaic mode stitches several frames to cover even wider areas.
Focal ratio
f/5
Fast enough that ten-second frames carry usable signal, which is what allows a recognisable image to appear within a few minutes of selecting a target.
Optical design
Sealed smart refractor with built-in camera
A four-element apochromatic lens with a fixed camera behind it and no eyepiece. The whole experience is on a phone or tablet, and several people can follow the same session at once.
Weight
5 kg complete
About 11 lb including the integrated mount. It fits in the supplied bag and sets up on any flat surface, which is central to how this class of telescope is meant to be used.
Mount
Integrated alt-azimuth GoTo
The telescope levels itself, plate-solves the sky and finds targets automatically, then tracks them while stacking. There is no alignment routine and nothing to focus.
