Not a finder

It is the thing two finders sit on. Filed under red dot finders because that is where the listing sits, and the first thing a reader needs to know is that ordering this alone leaves you with a bracket and nothing to put in it.

Two devices, one shoe

The bracket carries two Vixen/Synta-pattern bases and mounts on the telescope’s existing shoe. That means a red dot finder and an optical finder together, or a finder and a mini guide scope, without drilling anything.

The winter detail

Knurled screw threads, which the maker says can be turned with gloves at low temperatures. A finder that has to be adjusted with bare fingers at minus five is a finder that gets adjusted badly.

The weight to think about

Two finders on a bracket on one shoe is a cantilever, and a long one. No weight figure is published, and on a light tube the balance shift is worth checking before the first session.

Availability

German Amazon store sat at about 50 € on the day of the survey.

American and British Amazon stores list it in local currency, which the euro range above sets aside.

French, Italian and Spanish Amazon catalogues hold a record for it that nobody is selling.
