Clesthyra's Eye

First Appearance and Context

During an Apert visit to the rooftop Starhenge above the Præsidium in the Mynster, avout point out a small, fixed fisheye instrument that looks straight up at the sky. It is named for a mythic watcher able to look in all directions at once. The device’s pedestal includes a slot sized for a Photomnemonic Tablet.

Roles/Actions and Affiliations

  • All‑sky recorder: Captures the entire sky in a single view, making it ideal for registering the streaks left by fast‑moving objects (e.g., meteor trails).
  • Observational program: Measurements of these tracks allow cosmographers to infer where such objects come from, what they are made of, and how large they are.
  • Distribution and era: Similar Eyes were installed on starhenges worldwide around the time commonly called the Big Nugget, when attention to asteroids was especially high.

Relationships

  • Part of the rooftop complex of the Starhenge and physically mounted on the Præsidium above the Mynster.
  • Complements the dome‑housed telescopes by providing continuous all‑sky coverage.
  • Works in concert with a Photomnemonic Tablet, which can be inserted to accumulate and replay time‑series observations.

Descriptions/Characteristics

  • Form: A small dome‑like fisheye lens aimed at the zenith, fixed in place with no moving parts.
  • Mounting: Set on a carved stone pedestal with an integral tablet slot.
  • Name: "Clesthyra’s Eye" alludes to a legendary being reputed to see in all directions at once.

Current Status/Location

Installed and in use on the Starhenge atop the Præsidium within the Mynster, active during permitted rooftop work and observations.

Summary:

A fixed all‑sky lens mounted on the starhenge atop the Præsidium at the Mynster. It records the entire sky to photomnemonic tablets, chiefly to capture fast tracks such as meteor trails; similar devices were installed widely when interest in asteroids surged.
