NGC 2403

About this image

NGC 2403 is a mid-size spiral galaxy with an apparent magnitude of about 8.9, the 11^th brightest in our sky, is just bright enough for small to mid-sized telescopes and benefits more from darker skies than focal length. Its oblique orientation reveals a wealth of structures; loosely wound spiral arms, over 100 prominent H II regions, a mottled core but lack of distinct dust lanes, not unlike the Triangulum Galaxy M33 in many ways.

NGC 2403 is in the northern constellation Camelopardalis, approximately 10 million light-years away from Earth, and a member of the M81 Group of galaxies. Numerous bright star-forming regions and nebulae can be observed throughout its spiral arms, which are highlighted in the final image by the addition of Ha wavelength data.
