Clesthyra's Eye
First Appearance and Context
During a visit to the rooftop Starhenge above the Praesidium in the Mynster, avout identify a small, fixed fisheye instrument pointed at the zenith. Named for the mythic watcher Clesthyra, it is set into a stone pedestal with a slot sized for a Photomnemonic Tablet.
Roles/Actions and Affiliations
- All‑sky recorder: Captures the entire sky in a single view, well‑suited to registering transient streaks from fast‑moving objects.
- Recording cadence: With a tablet inserted, it accumulates observations continuously until the medium is full; at typical settings, a single run can span months.
- Complement to telescopes: Provides continuous coverage while dome‑housed instruments target specific fields.
Relationships
- Part of the rooftop complex and physically mounted on the Praesidium above the Mynster; designed to work with a photomnemonic tablet.
Descriptions/Characteristics
- Form: A small dome‑like fisheye lens aimed at the zenith, fixed in place with no moving parts.
- Imaging behavior: Under all‑sky projection, fixed stars form circular trails due to the world’s rotation, while fast‑moving objects trace straight, faint tracks.
- 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 rooftop, active during permitted work and observations; access follows the roof’s availability under the Discipline.
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.
