What to image in January with the ZWO Seestar S30 Pro
The long nights of midwinter belong to Orion. The Orion Nebula is up for hours, the emission regions around it (Flame, Horsehead, Rosette, the Christmas Tree cluster) respond to a dual-band filter even from town, and Andromeda and the Pleiades are still high in the west early in the evening. Cold, dry air is the best seeing of the year; dew and battery life are the enemies.
Moon in January 2027: new on 7 Jan, full on 22 Jan. Broadband targets (galaxies, clusters) want the week either side of new; emission nebulae behind a dual-band filter tolerate the rest.
37 targets transit near midnight in January. From a suburban sky the Seestar S30 Pro gets a solid image of 22 of them in under an hour each; 15 need longer, or a darker sky, or several nights. Times below use the recommended filter and 10 s subs.
