- NGC 2403
NGC 2403 is a spiral galaxy located in the northern constellation Camelopardalis. It lies outside the swath of the Winter Milky Way and is bright enough (visual magnitude 8.9) to be seen with binoculars under good sky conditions. This galaxy is reminiscent of M 33 (the Pinwheel Galaxy in Triangulum) in appearance. It has a physical diameter of around 50,000 LY and lies at a distance of around 8 million LY. Were it at the same distance as M 33 (2.74 million LY), it would be an equally impressive object.
NGC 2403 (also known as Caldwell 7) was discovered by William Herschel in 1788. Due to its high northern position in the sky (Declination +65.6 degrees), this object is circumpolar and can be seen year-around by observers in northern latitudes. The small fuzzy object amongst the stars in the lower right corner of my image is the distant magnitude 15.18 galaxy UGC03898.
This is a new version of this image created from raw Red, Green and Blue images acquired this year along with a similar set of images acquired back in 2013. Each set of images was processed with its own appropriate atmospheric calibrations and weight factors and then combined into a single set used to create the image.
