NGC 2403 is a fine galaxy easily visible in binoculars. It is surprising that Messier never found this bright galaxy. A small telescope will display a bright core surrounded by a speckled halo with many superimposed field stars. A larger telescope under dark skies starts to expose spiral structure in the halo. NGC 2403 is a member of the M81 galaxy group and contains many bright emission nebulae, a sure sign that lots of star formation is taking place in this galaxy.
