One bullet

The listing’s entire description is its own article number. Everything above comes from the title: an illuminator for a polar scope, threading M8 × 0.75.

Why it exists

An engraved reticle is invisible against a dark sky. There is nothing behind the lines to see them against, and a polar alignment cannot be made if the pattern cannot be seen. An illuminator solves it, and mounts are frequently sold without one.

The thread is the specification

M8 × 0.75. That is what decides compatibility, and naming it is the single useful thing in the listing. Whether another manufacturer’s polar scope carries the same thread has to be checked by measurement.

What is left to find out

The colour of the light, whether its brightness can be adjusted, and what powers it. All three matter in use, and none appears.

Availability

German, French, Italian and Spanish Amazon stores sat at about 27 € on the day of the survey.

British Amazon catalogue holds a record for it that nobody is selling.

American Amazon store gave no result whatever, so the buy button there opens a search rather than an empty page.
