SkySafari 4 Plus

SkySafari 4 Plus is everything in SkySafari 4, plus more. Now completely rebuilt for Android, Plus adds a hugely expanded database, wired or wireless telescope control, and spaceflight to SkySafari 4.

This version includes 2.5 million stars, 31,000 deep sky objects, the Solar System’s major planets and moons, and over 4,000 updatable asteroids, comets, and satellites. Simulate the sky from any place in the Solar System, up to 10,000 years in the past or future. Expand your astronomical knowledge with over 1500 encyclopedic descriptions of the constellations, stars, and planets. Enjoy more than 800 images from NASA space missions, the Hubble Space Telescope, and the world’s foremost astro-photographers.

With SkySafari 4 Plus, you can leave Earth’s surface behind. Tap the Orbit button to fly into orbit around other objects in the Solar System, and beyond it. Follow eclipses, occultations, and transits in Earth’s sky – and beyond! View the planets and their moons as only NASA space probes have – even label every crater on them.

SkySafari 4 Plus adds wired or wireless control for Celestron, Meade, Orion, SkyWatcher, and many other computerized telescopes. It can point your GoTo or “Push-To” telescope anywhere in the sky, using your device’s built-in Bluetooth, and a Bluetooth serial adapter (sold separately). Plan observing sessions with Observing Lists, log your observations into them, and share them with friends. More astronomers use SkySafari for telescope control than any other app!

SkySafari’s streamlined interface puts the universe at your fingertips. It turns your Android device into a 21st-century telescope controller. It’s hard to believe there’s even more in SkySafari 4 Pro – but Plus will keep anyone with a small backyard telescope busy for years. (Please note: there is no discount upgrade path from SkySafari 4 Plus to Pro.)

If you’ve used SkySafari Plus before, here’s what’s new in version 4:

* New look-and-feel, app icons, and artwork.
* Complete rewrite of compass code for much smoother and more accurate motion tracking.
* Google Maps integration: choose your location from a built-in Maps view.
* Animated meteor showers, with complete viewing information and spectacular graphics.
* New horizon panoramas: Yerba Buena Gardens in downtown San Francisco, Uluru (Ayers Rock) Australia, and the top of Mauna Kea on Hawaii’s Big Island. Or add your own!
* New and updated descriptions for hundreds of objects.
* Completely reinvented scope control panel. Up/Down/Left/Right controls only appear when the scope is connected, and big enough to be useable.
* Objects lists under Search are now sortable by name, number, magnitude, RA, Dec, and many other properties.
* New Advanced Search options let you find objects using properties other than their name. For example, you can find all objects of a certain type, within a certain constellation, brighter than a certain magnitude, etc.
* New Advanced Time settings let you enter a date & time thousands of years in the past or future, to the nearest second, or using Julian dates
* New Telescope Equipment settings let you enter a list of all your telescope equipment. Select different combinations of eyepieces and telescopes to display field-of-view automatically. Set up a separate camera and auto-guider FOV. All FOV indicators can be labelled in the sky chart.
* Now log observations of objects directly from the Object Info view, or show all your observations of any object at once.
* New Variable Stars list, containing the brightest and best-known variables in the sky.
* Added descriptions for dozens of asteroids, comets, and satellites; and many images.
* Dozens more tweaks, bug fixes, and additions we don’t have room to list here!
