About Stargazing Hub: Astro Guide
Celestial events happening? Use Stargazing Hub!
Stargazing Hub is a complete observing toolkit for astronomy enthusiasts, astrophotographers, and anyone starting to explore the night sky. It brings together a real-time star map, sky image recognition, observing forecasts, light pollution maps, satellite passes, and practical imaging tools so you can decide when to go out, where to observe, what to look for, and how to frame your shot.
Why choose Stargazing Hub?
· [Sky Image Recognition]: Analyze sky photos locally or online. Identify constellations, deep-sky objects, planets, and astronomical parameters to help you review your images and confirm target positions.
· [Real-Time Star Map and AR Sky]: Explore constellations, constellation artwork, traditional star lore, the Milky Way, deep-sky objects, comets, meteor showers, satellites, and viewfinder overlays. Use the star map for planning, or overlay it on the real sky with AR.
· [Real Observing Conditions]: Simulate light pollution, moonlight, twilight, horizon, terrain, and imaging conditions before you head out. For deep-sky targets, switch DSS layers to check background context and plan composition.
· [Viewfinder and Mosaic Planning]: Calculate real fields of view from cameras, lenses, telescopes, eyepieces, binoculars, and smart telescopes. Plan and export mosaic panels for wide deep-sky targets.
· [Stargazing Index Forecast]: Compare hourly observing quality using cloud cover, transparency, seeing, moonlight, wind, humidity, and more, so you can choose better observing windows.
· [Astronomical Calendar]: Track sunrise, sunset, moonrise, moonset, moon phases, Milky Way visibility, moonless windows, meteor showers, planets, comets, and other events.
· [Maps and Environment]: Check global light pollution, stargazing index maps, aurora maps, weather forecasts, air quality, and sunrise or sunset glow forecasts.
· [Satellites and Space Station]: View real-time positions, brightness estimates, and pass predictions for the Chinese Space Station, Starlink, and other satellites.
· [Astrophotography Tools]: Use calculators for night-sky photography, guiding accuracy, equivalent focal length, polar scope simulation, and red-light mode.
Download Stargazing Hub and keep your star map, forecasts, recognition tools, and imaging helpers in one place.
