October 2026 smart telescope observing guide
Quick summary· AI-generated
This October observing guide from Vaonis details optimal targets across both hemispheres, including the Heart Nebula (IC 1805) in Cassiopeia, the Small Magellanic Cloud, and seasonal galaxies like M31 and M33. The guide includes a lunar calendar identifying the best viewing windows (New Moon on Oct 10, Full Moon on Oct 26), the Orionid meteor shower peak (Oct 21–22), and specific filter recommendations (dual-band filters suggested for nebula work). It emphasizes timing observations to avoid moonlight interference and provides deep-sky object descriptions useful for planning mosaic imaging and wide-field sessions with smart telescopes.
Excerpt from Vaonis - Our travel journal
The northern sky offers an interesting mix of nebulae and galaxies. In the evening, the Summer Triangle is still high, with the emission nebulae of Cygnus, while, around midnight, M31, M33 are well placed. Cepheus and Cassiopeia also offer a rich set of nebulae. Winter targets (Orion, Taurus, Auriga) rise in the small hours.
The southern sky favors galaxies. Sculptor and Cetus are high in the evening, while Fornax and Eridanus rise progressively and are best placed around and after midnight. The Milky Way itself is at its best in the early evening and sets quickly around midnight. The Small Magellanic Cloud is well placed from the evening to around midnight, the Large Magellanic Cloud in the second half of the night.
October 2026 astronomical calendar
It is recommended to observe nebulae and galaxies when the Moon is not visible. Its brightness diminishes the darkness of the sky and reduces the quality of observations of faint and diffuse objects.
Refer to the following calendar for the best days this month.
3 October: Last Quarter Moon
6 October: the Moon occults Jupiter shortly before dawn. Visible from eastern and central North America and parts of Africa.
10 October: New Moon
18 October: First Quarter Moon
21-22 October: Orionid meteor shower peak. About 20 meteor per hour. Best window is the pre-dawn hours.
26 October: Full Moon
Celestial Scene of the Month
Northern sky
The Heart Nebula
IC 1805 is a large HII region in Cassiopeia, named for the heart-shaped outline visible in wide-field images. It is ionized by the young OB stars of the central open cluster Melotte 15. The main body measures about 1° across, roughly twice the apparent diameter of the full Moon, but the nebula does not end there: very faint extensions of ionized gas reach beyond 2° in deep exposures.The Fish Head Nebula (IC 1795), to the east, belongs to the same star-forming complex and can be included in a wider mosaic.
A dual-band filter is recommended.
Southern sky
The Small Magellanic Cloud is a dwarf irregular galaxy that orbits the Milky Way, about 200,000 light-years away. Its full extent is roughly 5° × 3°, about ten full-Moon diameters along the long axis, but its main body fits within a Vespera mosaic.
The SMC is a rare opportunity to image emission nebulae outside the Milky Way. The brightest region is the northeastern part of the main body, which contains NGC 346, the most prominent star-forming region in the SMC, and NGC 371. Fainter nebulae are…
