SkyShare
Identify Moon, planets and stars in night sky photos
A JavaScript package that reads photos of the night sky and returns the names and pixel positions of the Moon, planets and bright stars found in them.
Overview
The SkyShare homepage
SkyShare is a JavaScript package that analyzes photographs of the night sky to identify celestial objects. It reads the photo's metadata for time and location, calculates where the Moon, planets and bright stars were positioned at that moment, finds them in the image, and returns their names with pixel-level positions. Developers can use the returned positions to draw custom labels or let SkyShare draw them as a finished labeled image or transparent overlay. The package includes a label layer with small italic text and pointers for faint stars, available in story, portrait or square formats. It also provides raw sky data through an API endpoint returning the Sun, Moon, planets and thirty named stars for any time and place. When photos lack metadata, users can manually input time and place information, and when the image alone is ambiguous, SkyShare can request confirmation taps on identified objects to align labels correctly.

Buyer questions
How accurate is SkyShare at identifying objects in sky photos?
SkyShare successfully identified and placed celestial names in 6 of 22 test photos automatically. In 16 photos, it asked for one or two tap confirmations from the user to align labels correctly. It could not match 2 photos at all. Of the 16 requiring taps, 8 had other lights that could be confused with sky objects, 6 had ambiguous configurations, and 2 could not be matched.
Can I use SkyShare without the CycleCalcs brand?
Yes, you can use SkyShare under your own brand by agreement with CycleCalcs, with no CycleCalcs mark or your brand in its place. Offering the package as a kit to other developers or running it as an API for other companies' apps also requires agreement. Contact info@cyclecalcs.com for licensing terms.
What data can I get directly from the API?
The GET /v2/sky-targets endpoint returns the Sun, the Moon, the planets and thirty named stars for any time and place you specify, allowing you to draw your own labels and interface instead of using SkyShare's built-in rendering.
