What's New in Polar Scope Align Pro

7.0

July 5, 2026

Version 7 brings improved daytime alignment and many more tools and features: • Camera Azimuth Calibration added for Daytime / No Polar Scope alignment, using the Sun, Moon, planets or bright stars for higher accuracy instead of relying on the compass. • Improved Daytime Alignment, Laser / Hop Align, and Push To compass/magnetometer handling. • Phone mounting orientation options added for alignment and Push To tools. • Sky maps added to Push To, Hop To, Laser / Hop Align, and Daytime Alignment. • DSO Database lists can be saved, edited by swiping, and printed. • Xasteria updates: Widgets available (weather, satellite pass and aurora), OpenWeather forecast, aurora forecast map, improved weather display with sun/moon altitude arcs, in-app satellite trajectories, and updated light pollution map. • Bubble Level adds incline/slope percentage mode and Camera Az calibration support. • Auto Night Mode added. • New onboarding screens and improved help, especially for daytime calibration. • Magnetic declination calculation restored. • Various small fixes, including settings screen and iOS 26 compatibility updates. Remember, the app never nags you with popups, so it gets very few ratings/reviews. Support it by rating it!

Full Featured Well Designed, Great Functions

Something for everyone, observers and astrophotographers. I appreciate the DSO section- the ability to generate custom observing lists, and the “Push To” feature to orient my scope in Alt Az mode.

Mandatory app

If you do outreach or even move your telescope in and out of the garage or the house, this is an incredibly helpful setup tool for the night session or a solar session

Great for phone based polar alignment

I have been using phone apps to polar align my star trackers for a number of years as here in the southern hemisphere we don’t have a polestar to use. The update of this app (July 26) is a game changer as it totally removes the reliance on the magnetic compass and allows you to calibrate azimuth with a known star. I can get clean 10 minute tracks using 50 mm lens no problems with minimal hassle during set up (2 min). The developer has to be given huge kudos for a great job. Still some improvement I would like to see, but the app does the job brilliantly.
