IC 342 Hidden Galaxy with a smart telescope
IC 342 Hidden Galaxy is a spiral galaxy about 20 arcminutes (0.33°) across, magnitude 9.68. It is highest around midnight in November, best placed for the northern hemisphere, and faint and spread out; it really benefits from a dark site and a long total exposure. Of the 14 smart telescopes we track, eQuinox 2, eVscope 2, Odyssey frame it best.

Imaging tips
Galaxies shine in broad starlight, so light-pollution filters help little. What helps most is a darker site and a long total exposure: plan on one to three hours of stacking for the faint outer parts. Hidden Galaxy is a target for your darkest nights.
