Deneb is your co-pilot for night and landscape photography. Plan where and when to shoot the Milky Way, the Moon, the Sun, Orion, an eclipse or a meteor shower, always on the real terrain. FREE TO PLAN • Tonight: the astronomical night window, the Moon phase and the hours of true darkness, with a verdict on whether it's worth going out. • Clouds tonight: the hour-by-hour forecast, with cloud types and dew and wind warnings. • The Milky Way and the Galactic Center on a terrain map, step by step. • The Moon or the Sun behind a landmark: pick a church, a tower or a castle and Deneb tells you the dates, the time and where to shoot from. • Orion with a landmark, eclipses and meteor showers. • Composition viewer with your camera's focal length and sensor: check whether a mountain blocks the sky before you drive there. • Split screen 2D/3D and a joystick to fine-tune your shooting spot. • Augmented reality: point your phone and see where the Milky Way will rise. • NPF and hyperfocal calculators (150+ cameras), lunar calendar and packing list. • Home screen widgets for the night and the clouds. • Chat assistant to answer your questions about the app. DENEB PRO Pro adds what costs money to keep running: • The real landscape in 3D: the viewer and the map show Google's photorealistic mesh —terrain, buildings, trees— behind your framing. • 3D landmarks: places we modeled ourselves where Google doesn't reach, such as castles, windmills, telescopes, lighthouses and churches, with their real outline in the viewer. • Automatic search for the best spots and dates for the Moon, the Sun or the Milky Way over your landmark, also inside an area you draw on the map. • Timelapse and star trails: watch the sky move over your landscape and record it as a video. • Panorama: the shot grid with its overlap, the maximum exposure and the final photo already stitched. • Unlimited saved plans (Deneb Free saves 15). Deneb Pro is a monthly or yearly subscription; the yearly plan starts with a one-week free trial. It renews automatically unless you cancel at least 24 hours before the end of the current period, and you can manage or cancel it in your App Store account settings. Made by Josep Guasch, photographer and astrophotography instructor. You'll also find his landscape and astrophotography workshops in the app. Terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy: https://deneb.photo/privacidad.html
