A listing that explains itself

Five bullets, and between them they set out what a polar scope is for, why the hour axis has to be parallel to the Earth’s axis, when that precision is needed, and when it is not. That last point — that visual observing needs only the latitude setting and a compass — is a statement against interest, and it is the most useful sentence in the listing.

The part itself

A polar finder for the iEXOS-100. Mount-specific, as polar scopes are, because the bore and the fitting differ between manufacturers.

The blanks in the listing

Accuracy in arcminutes, magnification, field of view, illumination. Those four would let it be compared with the Vixen scope on this shelf, which publishes three of them.

Where the line falls

Visual: latitude and a compass. Photography: a polar scope, and how accurately it is set determines how long an exposure can run before stars trail. The maker draws that line clearly, which is exactly where it belongs.

Availability

German, French, Italian and Spanish Amazon stores sat at about 76 € 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.

    • The counterweight can carry a second camera, so two focal lengths run at once
    • It is a mount, and the family heading says polar scopes

    • The maker states exactly what has been removed to reach the price
    • Mechanical drive, so nothing to charge and nothing to fail in the cold
    • A sighting tube is far coarser than an optical polar scope, which limits exposure length

    Best for: Wide-angle tracked photography where a coarse polar alignment is enough
