Gosky 20-60x80 review

A 20–60x80 spotting scope with BAK4 porro prisms and fully multi-coated optics, supplied with a full-metal tabletop tripod, a phone adapter and a carry case.

The bottom line A well-equipped daytime scope whose published field of view has lost its meaning somewhere in translation.

What eighty millimetres gives at each end

Divided by twenty, the objective yields a 4 mm exit pupil — bright, comfortable, and usable at dusk. Divided by sixty it yields 1.3 mm, which is dim and demands that the eye sit exactly right. Every zoom spotting scope behaves this way, and knowing the arithmetic sets the expectation.

The accessories are the value

A full-metal tabletop tripod, a digiscoping adapter, a carry case, lens covers and a cleaning cloth. At this price that is a complete outfit, and the metal tripod in particular is a step above the plastic ones usually supplied.

The figure that does not parse

The second bullet offers “a field of view of 1000 metres”. Field of view is an angle: 2.06 degrees, or 36 metres at 1000 metres, or something of that form. What is printed cannot be read as either, and this page reports it rather than inventing a figure.

Where it stops being astronomical

The zoom eyepiece is built in. Without a 1.25 in barrel there is no way to fit a proper astronomical eyepiece, a nebula filter or a Barlow — which is the boundary between a spotting scope and a small telescope.

What it publishes, and what it withholds

Strengths

  • A full-metal tabletop tripod is supplied rather than a plastic one
  • Eighty millimetres of objective keeps the 20x end genuinely bright
  • Complete accessory set: adapter, case, covers and cloth all itemised

Compromises

  • The field of view is published as a distance, which describes nothing
  • At 60x the exit pupil falls to 1.3 mm, which is dim and hard to hold the eye in
  • The zoom eyepiece is not removable for an astronomical one

What observers ask about this one

Can a spotting scope be used on the night sky?

Yes, within limits. At the 20x end an 80 mm objective gives a 4 mm exit pupil, which shows the Moon well, Jupiter’s moons and bright clusters. What it lacks is a removable eyepiece and an equatorial mount.

What is wrong with the field figure?

Field of view is an angle, usually written as degrees or as metres at 1000 m. “A field of view of 1000 metres” is neither, and nothing in the listing supplies the missing half of the figure.
