IC 63 Ghost of Cassiopeia with a smart telescope
IC 63 Ghost of Cassiopeia is a emission nebula about 10 arcminutes (0.17°) across. It is highest around midnight in October, best placed for the northern hemisphere, and works from a suburb; a darker site gives a much cleaner result. Of the 14 smart telescopes we track, Odyssey, Odyssey Pro, eQuinox 2 frame it best.

Imaging tips
This type glows in the specific colours of hydrogen and oxygen. If your smart telescope has a dual-band or light-pollution filter, use it: it blocks much of the city glow while letting the nebula through. Ghost of Cassiopeia is a reasonable target from the suburbs.
