Supernova SN 2014J, in galaxy M82, Ursa Major
A Note marks the location of the Type 1a supernova, which I first saw last Wednesday - shortly after it was discovered. The explosion actually happened about 12 million years ago, but the light has only just reached us.
Manually, off-axis guided for 7 x 5-minute exposures at ISO 1600, f/4.
Modified EOS 600D & Revelation 12" Newtonian reflector telescope.
Registered and stacked using DeepSkyStacker; initial curves adjusted and noise reduced in Canon Photo Professional; final curves & colour-balance adjusted using Paint Shop Pro.
