Scores are estimated from moon phase, moonlight interference and dark-window timing for New Taipei. This first version does not include cloud cover, so always check weather.
🌌 Sep is a good window for the Milky Way core over New Taipei: it climbs to a shootable altitude around 19:16, sinks back down near 22:16, and peaks around 19:16 at roughly 33° in the South. Avoid moonlight and face that direction to catch the bright galactic center.
That is where the core sits in the sky over New Taipei — not a promise you can see it. Under city lights the galactic core is essentially invisible, and photographing it usually means leaving the urban glow behind. Browse the dark-sky catalogue →

The New Taipei calendar combines Moon phase, dark windows, and short-range conditions, but the score still needs local context and light pollution checks.
Score
High scores mean friendlier moonlight and night windows, and short-range views can include cloud and transparency. Local fog, patchy cloud, and nearby lights can still change the outcome.
Moonlight
Full-moon periods light the landscape but reduce faint-star and Milky Way contrast. For the Milky Way, meteors, or deep-sky targets, new-moon periods are usually better.
Dark window
Dark outside is not always dark enough. The dark window considers twilight ending, Moon rise and set, and the length of usable night.
After choosing a good date, confirm location, direction, and hourly weather for the night.
Short range
Moon phase can be planned months ahead, but cloud needs a short-range forecast. For the actual night, use hourly stargazing index and on-site observation.
Place
High elevation may help with low cloud, but nearby lights can still wash out the sky. Use the dark-sky map to remove weak candidates first.
Direction
A site may only work for certain horizons. Use the sky map to check the galactic center, Moon, and constellations before facing sea, mountains, or city lights.
Grouped by driving reachability and straight-line distance. Bortle is a long-term darkness class, not a live score for tonight.
