Xelmu

Xelmu is a personal astrophotography journal designed for amateur stargazers and night-sky photographers. Capture and organize your celestial imaging sessions by importing photos from your camera roll, recording technical gear settings (camera, lens, telescope, ISO, shutter speed, aperture), and logging environmental conditions like location, weather, moon phase, and seeing quality. Browse your cosmic archive through a filterable gallery organized by target type—Moon, Planets, Nebulae, Galaxies, Star Clusters—and compare multiple exposures side-by-side. Build a private visual catalog of your astronomical captures with immersive deep-space aesthetics in midnight navy and cosmic purple tones.
