Groovy Stars Sky Atlas

A free, beautiful sky atlas for stargazers and imagers: 1,000,000+ deep-sky objects, live planets and Moon, night-vision red mode, a planner, and telescope control.

Groovy Stars is a free, native sky atlas for iPad — built for both visual observers and imagers, from a quick look at what's up tonight to planning a full night at the eyepiece.

THE SKY, IN DETAIL

• A deep star field down to magnitude 15, plus over 1 million deep-sky objects — galaxies, nebulae, and star clusters. • Constellation figures, names, and official boundaries. • Realistic planets: textured globes with true phases, Saturn's rings, and the brighter moons — including transits, shadow crossings, and mutual events. • A detailed Moon with labeled craters, maria, and mountains, correct phase, and lunar-eclipse shading. • The Sun with the current day's sunspots. • Comets, meteor showers, conjunctions, variable-star light curves, and a live feed of bright supernovae.

SEE IT YOUR WAY

• Horizon (alt-az) or equatorial view, with dome, stereographic, and orthographic projections. • Real horizon panoramas, or draw your own custom horizon for your site. • A measuring tool for angular distances. • Sketch what you see at the eyepiece with Apple Pencil.

PLAN YOUR NIGHT

• A powerful planner: rise, transit, and set times, altitude, airmass, and distance from the Moon for every target. • Filter by type, constellation, magnitude, altitude, and Moon separation. • Imaging mode scores each target for tonight and shows how it frames in your camera — including smart scopes like the Seestar. • Save telescope and camera profiles, build observing lists, and load Astronomical League program lists or import your SkySafari lists.

KEEP A LOG

• Record your observations and export or import them in the Open Astronomy Log (OAL) format, so your data stays yours.

AT THE EYEPIECE

• A true night-vision red mode — even the menus and date pickers stay a readable red, to protect your dark adaptation.

CONTROL YOUR TELESCOPE

• Point your mount over your local network with ASCOM Alpaca, LX200, or INDI — push-to and go-to.

ON YOUR HOME SCREEN

• A "This Week in the Sky" widget with the week's best events at a glance.
