Thousands of frames, and only the sharpest kept · review
A basic USB electronic eyepiece for a 1.25 in focuser with automatic white balance, sold on a listing that repeats its first bullet six times.
The bottom line The same class of camera as its neighbours, sold behind a listing that says one thing six times and nothing else.
Six of this product’s bullets are the same paragraph, word for word, with a different trailing keyword each time. A seventh is a customer testimonial. What survives as specification is: a 1.25 in barrel, USB, automatic white balance, and a repeated statement that it is not for deep-sky imaging.
It goes into a 1.25 in focuser or a reducing adapter. It sends live video to a PC over USB. It is not intended for faint objects. That is the maker’s own description, minus the repetition.
The testimonial names USB 2.0. That sets a ceiling on how much data leaves the camera each second, and therefore on frame rate — which is the figure that decides how many moments of steady air get captured during a planetary run.
As a first, inexpensive experiment in putting the Moon on a screen. Anything more demanding argues for a camera that names its sensor.
German, French, Italian and Spanish Amazon stores ran from 25 € to 38 € 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.

One bullet quotes a customer reporting that the camera was recognised under Windows 10 and used with common capture software, delivering smooth images. It is a customer statement placed in a specification field, and it is reported here as exactly that.
It caps how much data per second can leave the camera, which caps the frame rate at a given resolution. For the Moon it is adequate; for planetary stacking, more frames per second means more sharp ones.
