Thousands of frames, and only the sharpest kept · review
A Wi-Fi camera that clamps around an existing eyepiece rather than replacing it, with a 1.47 in screen, app control and a 32 GB card supplied.
The bottom line A versatile afocal recorder that fits almost anything, at the cost of shooting through an extra optic.
It clamps around an eyepiece rather than going into the focuser. That single fact explains both its versatility — telescopes, binoculars, microscopes, spotting scopes — and its ceiling, because everything it records has already passed through an eyepiece designed for an eye rather than a sensor.
Four megapixels, Full HD video, a 1.47 in screen, an app for Android and iOS, and a microSD slot with a 32 GB card already in it. The screen is the part that matters most: it makes framing possible without a phone, in the cold, with gloves on.
One to five minutes, per the maker. That is an unusual feature here and a useful one for a meteor watch or for catching a transit, where the interesting second is not known in advance.
The sensor model and its pixel size. As with almost everything on this shelf, the megapixel count is given and the figure that would let it be matched to an instrument is not.
German, French, Italian and Spanish Amazon stores ran from 99 € to 115 € 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.

A clamp-on camera photographs the image the eyepiece has already formed, which is called afocal. It works on any instrument, and it adds the eyepiece’s own aberrations and vignetting to the result. A camera in the focuser sees the telescope’s image directly.
Because the clamp has to grip the eyepiece body. Thirty to sixty-five millimetres covers most astronomical eyepieces and many binocular oculars, which is why this camera is sold as universal.
