SkyPlan.Space — An astrophotography night planner

Field notes

The planner is organized around the practical losses in an imaging session, including telescope slews, refocusing, filter changes, and the meridian flip. Its stated scoring model exposes cloud, Moon, altitude, duration, and light pollution as separate factors, while missing seeing data lowers confidence rather than silently becoming a zero. The public catalogue covers 15,935 objects across 26 named or referenced catalogues, and saved sessions are described as exportable to JSON, CSV, calendars, and N.I.N.A. target lists.
