DeepSky is a dedicated astronomy observation toolkit for amateur stargazers. Log every deep-sky object you observe, track moon phases and planetary positions, manage your telescope and eyepiece gear, draw hand-made star chart sketches, and assess light pollution and sky conditions at each session. All your records stay linked on your device so you can review what you saw, where you saw it, and how the sky behaved that night.
