M110 with a smart telescope

M110 is a elliptical galaxy about 22 arcminutes (0.37°) across, magnitude 8. It is highest around midnight in September, 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 12 smart telescopes we track, Seestar S50, Origin Mark II, 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. M110 is a target for your darkest nights.
