Thousands of frames, and only the sharpest kept · review
A clamp-on electronic eyepiece with a three-inch colour LCD, adjustable focus and brightness, published at 3840 × 2160 and sold for birdwatching as much as for the sky.
The bottom line A clamp-on recorder with a usable screen and an adjustable one — specified for daylight, used at night at the buyer’s risk.
Three thousand eight hundred and forty by two thousand one hundred and sixty. That is a dimension rather than a word, and it is more than several neighbours on this shelf offer. What is absent is the sensor behind it, so whether those pixels are captured or interpolated cannot be determined here.
Every lit screen costs dark adaptation. A camera whose display can be dimmed in steps can be used between looks through the eyepiece; one that cannot becomes a choice between recording and seeing.
Four of its five bullets discuss wildlife and daytime observation, and the night-view technology is named without a figure. Read as a birdwatching accessory that also works on the Moon, it makes sense.
Twenty-two to forty-six millimetres of eyepiece body — the same range as its close neighbour here, and narrow enough that a large wide-field eyepiece should be measured first.
German and French Amazon stores ran from 50 € to 53 € on the day of the survey.

More than it sounds. A screen at full brightness resets dark adaptation in a second, and twenty minutes are needed to recover it. Being able to dim it is the difference between using the camera and losing the rest of the session.
The sensor model, the pixel size, the frame rate and the exposure range. Without those there is no way to say how it will behave on anything fainter than the Moon.
