IC2574 Coddington's Nebula and IFN IC 2574, also known as Coddington's Nebula, is a dwarf spiral galaxy[7] discovered by American astronomer Edwin Foster Coddington in 1898.[8][9] Located in Ursa Major, a constellation in the northern sky, it is an outlying member of the M81 Group. It is believed that 90% of its mass is in the form of dark matter.[10] IC 2574 does not show evidence of interaction with other galaxies. It is currently forming stars; a UV analysis showed clumps of star formation 85 to 500 light-years (26 to 150 pc) in size.[1 L 900secx11 Bin1 Alpi Friulane Novembre 2025 - Casera Razzo (1.800 mt. s.l.m.)

Complex processing for this galaxy both for the management of the Ha signal and for the presence of IFNs (i.e. faint background nebulosities illuminated by the Integrated Flux of all the stars of the Milky Way)
