M8 Lagoon Nebula with a smart telescope

M8 Lagoon Nebula is a star-forming nebula about 90 arcminutes (1.50°) across, magnitude 5.8. It is highest around midnight in June, best placed for the southern 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 S30 Pro, DWARF 3, Vespera Pro 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. Lagoon Nebula is a target for your darkest nights.
