Milky Way Position Calculator — Core Visibility Planner
Estimate when and where the Milky Way core will be visible from your latitude.
How We Calculate This
The Milky Way galactic core is located in the constellation Sagittarius at approximately Right Ascension 18h, Declination -29°.
Maximum altitude = 90° - |latitude - core declination|
The core's visibility depends on the time of year (when it transits during darkness) and your latitude (which determines how high it rises). From the UK at ~52°N, the core never rises higher than about 9° above the horizon (90° − |52° − (−29°)| = 9°), making southern hemisphere locations far more favourable for dramatic Milky Way photography.
Best viewing times shift approximately 2 hours earlier each month as the Earth orbits the Sun.
Frequently Asked Questions
In the UK (latitude ~51-55°N), the Milky Way core is visible from April to September. Peak season is June-July when the core is highest above the southern horizon. The best hours are typically between 11pm and 3am during these months, during astronomical darkness.
The galactic core (in Sagittarius, at declination -29°) is only above the horizon during certain months depending on your latitude. From northern latitudes, it is highest in summer when the Earth's nightside faces the galactic centre. In winter, it is below the horizon during dark hours.
From the UK (latitude ~52°N), the galactic core (Sagittarius A*, declination -29°) reaches a maximum altitude of only about 9° above the southern horizon (around 10° from London at ~51°N). This is very low, so finding a location with a clear, completely unobstructed southern horizon is essential.
Yes, dramatically. Even a quarter moon can wash out the Milky Way. Plan your sessions around the new moon (±5 days). Use the Moon Phase Calculator to check lunar conditions. Also avoid shooting when the moon is above the horizon.
