Install the almanac as an app on your phone — it opens full-screen with no browser bars, and once installed it works completely offline. Perfect for dark-sky sites with no signal.

Sets the latitude & longitude used for rise/set, twilight, the moon, planets and deep-sky positions across Forecast, Objects, Finder, Meridian, and Sun & Moon. The dark-sky maps are unaffected.

If the Moon or Milky Way markers drift as you pan the camera — sitting right when centered but sliding off toward the edges — nudge this until a marker tracks a known object across the whole frame. Lower = the markers move faster across the screen.

If the star and planet markers sit in the wrong place, the fix takes one tap. Open the Sky Finder, tap Align in the tools row, and the app picks the brightest unmistakable thing in the sky right now — the Moon, a bright planet, or a bright star — and tells you exactly what to aim at. Center it in the crosshair and tap Align. That\u2019s it. Phone compasses are often off by 10\u201330\u00B0; this corrects it in a second.

If you\u2019d rather fine-tune by hand, or your compass is only slightly off, nudge the whole sky left/right (compass) and up/down (altitude) until the markers sit on the real objects. These add to whatever Quick Align set.
