The one that fits in the bag is the one that gets used · review
A 70/400 travel refractor with a 45° erecting diagonal, four Moon filters, a shutter release, a phone adapter and a backpack.
The bottom line A thoughtfully equipped travel set whose numbers mostly add up, with a diagonal chosen for the ground rather than the sky.
Four hundred divided by twenty-five is sixteen; four hundred divided by six is sixty-seven. Those are exactly the magnifications the maker quotes for the two supplied eyepieces, which is a small thing and a reassuring one — plenty of listings on this shelf quote figures that do not follow from their own specifications.
Ninety-nine and a half per cent transmission, with no wavelength attached. Coating performance varies across the spectrum, and a percentage without a band is a number that cannot be compared with anything. It is reported here because the maker publishes it, not because it can be checked.
Forty-five degrees is the terrestrial angle. Combined with the erecting function and the shutter release, this is a set built at least as much for landscapes and daytime photography as for the sky. For objects high overhead, a 90° diagonal would be the addition to make.
Forty to ninety centimetres. That range decides whether a child can use it standing and an adult can use it seated, and publishing both ends is more useful than the word “adjustable” ever is.
German, French, Italian and Spanish Amazon stores ran from 55 € to 84 € on the day of the survey.
British Amazon store lists it in local currency, which the euro range above sets aside.
American Amazon store gave no result whatever, so the buy button there opens a search rather than an empty page.

It puts the eyepiece at a comfortable angle for horizontal viewing, which suits landscapes. Pointed high, it forces the head into an awkward position — a 90° diagonal is the usual astronomical choice.
They cut brightness by different amounts. Without published transmission percentages there is no way to compare them with any other filter, which is the recurring problem on this shelf.
