About this image

Coddington’s so-called ‘nebula’ is actually a dwarf spiral galaxy (IC2574) and is an outlying member of the M81 group. But, given E. F. Coddington discovered it in 1898, the term ‘nebula’ was the best description at the time. The image uses an H-alpha filter to highlight possible star-forming regions, shown in pink. The galaxy is very faint and I took nearly 3 hours of luminance to help form the basic image.
