Best Nights in May
✦Darkest skies
May 4 – May 8
Around the New Moon (May 6), little moonlight — the best nights for the Milky Way, meteors and faint deep-sky objects.
◐Sharpest Moon detail
May 13 · May 28
At the quarter Moons the terminator throws long shadows across crater rims — the best nights to photograph lunar surface detail.
○Brightest nights
May 19 – May 21
Around the Flower Moon (May 20), strong natural moonlight for night walks — but it washes out fainter stars.
