The function is clear enough

It extends a telescope finder base, so that a second accessory can be mounted where there was room for one. That is a real need and a cheap solution.

The description is not

Four bullets. One says the product is a hundred per cent brand new. One says it is easy to install. One repeats the function. One says the metal is durable. No length, no profile, no thread, no hole spacing.

What to compare it against

The 48 mm plate on this shelf, which at least publishes its length, and the dual finder bracket, which names its profile as Vixen/Synta and describes its screws. Both cost more and both can be checked.

Buying it sensibly

Measure the finder shoe on the telescope. Look at the photographs. Treat it as a low-cost experiment, because that is what the listing supports.

Availability

German, French, Italian and Spanish Amazon stores ran from 8 € to 13 € 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.

Figures as Keepa reported them on the day this page was last updated. Stock and pricing shift without warning.
