What to image in October with the Unistellar Odyssey

Long dark nights and the autumn sky: Andromeda and Triangulum, the Heart and Soul nebulae, the Pleiades late in the evening, the Helix low in the south. Still time for the Veil before it sets. Dew season begins in earnest.

Moon in October 2026: new on 10 Oct, full on 26 Oct. Broadband targets (galaxies, clusters) want the week either side of new; emission nebulae behind a dual-band filter tolerate the rest.

29 targets transit near midnight in October. From a suburban sky the Odyssey gets a solid image of 8 of them in under an hour each; 21 need longer, or a darker sky, or several nights. Times below use the recommended filter and 4 s subs.

Solid image with the Unistellar Odyssey, sorted by the Bortle 6 figure. Each link opens the full Bortle 1 to 9 table with sub-length and filter comparisons.
