Vintage Prinz Optics Astral Telescope Model 20 – 25x30 Monocular with Leather Case & Original Box (c.1970s, Japan)
.
Why We Love It
There’s something wonderfully nostalgic about this piece. A pocket telescope from a time when adventure felt closer—when a walk could turn into a discovery, and a view across the water was worth pausing for.
.
This Prinz Astral Telescope captures that spirit perfectly. Compact, beautifully engineered, and complete with its original leather case and box, it’s both a functional optical instrument and a charming relic of 1970s travel culture.
.
It’s the kind of object that feels just as at home in the hand as it does styled on a shelf—quietly telling its story.

A Little History
Prinz Optics was a house brand associated with major UK photographic retailers, most notably Dixons. Rather than manufacturing directly, Prinz sourced high-quality optics from Japan—then the global leader in precision optical engineering.
.
During the mid-20th century, Japanese-made optics earned a reputation for excellent clarity, reliability, and craftsmanship, making them highly collectible today.
.
This piece is a lovely example of that era—where practical engineering met accessible adventure.
