SkyPortal
Torrance, California, United States
What it is
SkyPortal is a free planetarium app and telescope control solution developed with the SkySafari app developers. Its catalog covers the Solar System, 120,000 stars, more than 200 star clusters, nebulae, galaxies, and dozens of asteroids, comets, and satellites, including the ISS. The app can simulate the sky up to 100 years in the past or future and create a list of celestial objects based on time, date, and location. Observation features include Compass Mode, Night Vision Mode, hundreds of astronomical and NASA spacecraft images, and more than four hours of audio narration. With a compatible Celestron WiFi telescope, users can align it and tap an object to center it in the eyepiece. SkyPortal also works with the separately sold SkyPortal WiFi Module and StarSense AutoAlign, but not third-party WiFi telescopes or modules. It is available for Android 12 and later and iOS 18 and newer, including iPhone XR and newer. The listed version 3.1.0.9067 features include All-Star Polar Alignment, tilt-to-slew, French and Italian localization, and augmented reality on iOS. Celestron offers support by live chat, email, or phone, plus a knowledge base.
