Re_Align

for iPhone

Re_Align walks you through setting up an equatorial mount, step by step and entirely offline. It fixes your position, sets the polar axis altitude for your latitude, levels the tripod with an inclinometer bubble, and finds true north — falling back to the computed solar azimuth when a magnet nearby spoils the compass, so you never have to look at the Sun. After dark it puts Polaris on a live polar-scope reticle at its real clock position, and logs the session in a report you can review later. Night mode throughout.
