Polar Scope Align Pro

Polar Scope Align Pro is a complete toolkit for amateur astronomers: accurate polar alignment, deep-sky observing, astro weather, push-to/manual GoTo, iOptron mount WiFi control, widgets and more. All features and updates are free forever. Optional in-app purchases are just tips to support development.

POLAR ALIGNMENT

• Calculates Polaris or σ Octantis position for 30+ reticle types: iOptron, Astro-Physics, Takahashi, Skywatcher, Vixen, Celestron, Orion, Astrotrac and others*

• Atmospheric refraction correction for accuracy at any latitude

• Works with or without a polar scope

ALIGNMENT WITHOUT A POLAR SCOPE

• Daytime / No Polar Scope Alignment: works day and night with just your phone's gyro

• Camera Azimuth Calibration: use sun/moon/stars to calibrate gyro and align accurately without a compass, immune to magnetic interference

• Laser / Hop Align: nighttime alignment for maximum accuracy with a laser or a scope with no view of Polaris

• Live sky map guides you to the celestial pole in real time

• Sun Finder helps you point your filtered telescope/telephoto to the Sun

PUSH TO (MANUAL GOTO)

• Attach your phone to any scope and convert it to manual/push GoTo

• Select from a large database and use direct push or more accurate hop-to mode

DEEP SKY OBJECT DATABASE

• 22,000+ objects with altitude graphs, rise/set times and more info

• Save and manage curated observing lists

• Filter, search, sort and push to any target

XASTERIA ASTRO WEATHER

• Hourly astronomy forecasts (7Timer, OpenWeather, MET Norway, Apple Weather)

• Aurora forecasts

• ISS and bright satellite passes with sky chart, live map tracking, and Tiangong and Hubble views

• Solar eclipse tool with past and future eclipses, live mode with audio cues

• Experimental eclipse camera for automated photoshoots of partial phase, diamond ring, Baily's beads, totality bracketing

• Light pollution data from the World Atlas and recent VIIRS satellite radiance

CALCULATORS & TOOLS

• 30+ calculators for observing and astrophotography

• Moon phase calendar with altitude graphs

• Solar eclipse calculator and simulator

• Bubble level & Compass

IOPTRON WIFI MOUNT CONTROL

• Connect to WiFi-enabled iOptron mounts (HAE, HAZ, HEM, CEM, GEM and more)

• Automatic date/time/location setup

• Switch between Equatorial and Alt-Az on mounts that support both

• Move & Sync: directional control with a live sky map

• Point GoTo: aim your phone at a patch of sky and send the mount there

• Current Point Query: find out what the mount is pointing at

• GoTo any object from the DSO Database

NIGHT-FRIENDLY

• Red, green or white night mode with dimmer

WIDGETS

• Tonight's weather, satellite passes and aurora forecast
