A full Moon washes out the deep sky: nebulae fade, galaxies disappear, and the faintest stars are no longer visible. Conversely, a moonless night under a truly dark sky reveals the most spectacular sights of the deep sky: the Milky Way, nebulae, star clusters, and galaxies.<\/p>\n<p>In November 2026, the New Moon occurs on the 9th at 7:02 a.m. UTC. The Moon will be absent from the sky from approximately November 5 through 12. That\u2019s a full week of astronomically dark nights. Enjoy it.<\/p>\n<h2>November's Targets: What Are We Seeing?<\/h2>\n<h3>M42: The Orion Nebula<\/h3>\n<p>The Orion Nebula is the most spectacular object in the fall sky. Visible to the naked eye as a fuzzy patch in Orion\u2019s sword, it appears through binoculars as a greenish nebula with the Trapezium star cluster at its heart. Through an 80\u2013100 mm telescope, details become apparent: the nebula\u2019s dark wings, the four-star Trapezium, and its outward extensions.<\/p>\n<p>Orion rises around 8 p.m. in November and reaches its highest point around midnight. It\u2019s the ideal subject for a long-exposure astrophotography session.<\/p>\n<h3>M31: The Andromeda Galaxy<\/h3>\n<p>The Andromeda Galaxy is the closest galaxy to ours and is visible to the naked eye under a dark sky. It appears as an elongated patch in the constellation Andromeda. Through binoculars, it is clearly visible. Through a telescope, you can see its bright nucleus and spiral arms.<\/p>\n<p>M31 reaches its highest point in the sky early in the evening in November. It\u2019s the first target of the evening, before Orion rises high in the sky.<\/p>\n<h3>M45: the Pleiades<\/h3>\n<p>The Pleiades are the most famous star cluster in the sky. Seven stars are visible to the naked eye, and dozens more with binoculars. Through a telescope, the bluish reflection nebula surrounding the stars appears against a dark sky. The Pleiades rise late at night in November and reach their highest point around 2:00 a.m.<\/p>\n<h3>M1: The Crab Nebula<\/h3>\n<p>The Crab Nebula is the remnant of a supernova observed in 1054 by Chinese astronomers. It is located near Taurus, about 1\u00b0 north of Zeta Tauri. With a magnitude of 8.4, it is invisible to the naked eye but visible through a 100-mm telescope as a faint, elongated patch.<\/p>\n<h2>How to Observe and Take Photos<\/h2>\n<h3>With the naked eye and binoculars<\/h3>\n<p>To make the most of the dark sky, the easiest thing to do is to go outside under a sky far from the city. A pair of 10\u00d750 binoculars is enough to spot M31, M45, and M42. The Milky Way is visible to the naked eye under a Bortle 1\u20133 sky.<\/p>\n<h3>Astrophotography without tracking (camera tripod)<\/h3>\n<p>A mirrorless or DSLR camera with a wide-angle lens (14\u201324 mm) at f\/2 or f\/2.8, mounted on a camera tripod. Exposures of 10 to 20 seconds at ISO 1600\u20133200. Photograph the Milky Way, the sky around Orion, and the Pleiades in a wide-angle shot. The Rule of 500 (500 \/ focal length in mm) determines the maximum exposure time before star trails appear.<\/p>\n<h3>Astrophotography with tracking (star tracker or tracking mount)<\/h3>\n<figure><img decoding=\"async\" src=\"https:\/\/deep-space-astronomy.ch\/wp-content\/uploads\/2025\/06\/Skyliner-250P-Classic-10668-avec-arriere-plan-supprime.avif\" alt=\"T\u00e9lescope Sky-Watcher Skyliner 250P Dobson d\u00e9tour\u00e9\" \/><figcaption>A telescope for nighttime use, under a dark sky. Credit: Sky-Watcher.<\/figcaption><\/figure>\n<p>With a star tracker or an AM3N equatorial mount, exposure times can reach 60 seconds or more. You can photograph M42, M31, and M45 in greater detail. Exposures of 60\u2013120 seconds at f\/4\u2013f\/5, ISO 800\u20131600, using either a wide-field or small telescope, produce stunning results. An 80\u2013100 mm telescope on a tracking mount (AM3N, Wave 100i, Star Adventurer GTi) is ideal.<\/p>\n<h3>Telescope Astrophotography (Deep Sky)<\/h3>\n<p>For nebulae and galaxies, an 80- to 200-mm telescope on a tracking mount, with an astrophotography camera (ASI2600MC, ASI533, ASI585) and a light pollution filter. Exposure times ranging from 60 to 300 seconds, stacked over 1\u20133 hours, reveal nebulae in all their depth. This is why the dark window of the new moon is essential: without the moon, the sky background is darker, the signal-to-noise ratio is better, and faint nebulae become visible.<\/p>\n<h2>The Window Calendar<\/h2>\n<ul>\n<li><strong>Nov. 5\u20138<\/strong> : A very thin crescent moon, setting early. The sky is dark as soon as night falls.<\/li>\n<li><strong>Nov. 9<\/strong> : New Moon at 8:02 a.m. CET. The darkest night of the month.<\/li>\n<li><strong>Nov. 10\u201312<\/strong> : A very thin crescent moon, visible at the end of the day. Dark skies until sunset.<\/li>\n<li><strong>Nov. 13 and beyond<\/strong> : The moon is getting bigger, and the sky is clearing up. Window finished.<\/li>\n<\/ul>\n<p>The best night is the night of November 8 to 9 or November 9 to 10: the Moon is completely absent, and the sky is as dark as it can be.<\/p>\n<h2>Why shop at Deep Space Astronomy?<\/h2>\n<p>We're not just a retailer.
