Mirach’s Ghost (NGC 404) in Andromeda
NGC 404 is truly a hidden treasure. This bright (mag 9.8) lenticular galaxy lies a little more than 6′ northwest of the 2nd-magnitude gold star Beta Andromedae (Mirach). Beta’s light interferes with — but does not drown out — this round little gem. NGC 404 is the nearest lenticular galaxy to our Milky Way at a distance of 8 million light-years.
The vicinity of NCG 404 to Mirach and the huge difference in brightness (8 magnitudes) made the processing of the image demanding. In addition, many reflections on surfaces in the optical train appeared when data have been stretched. North is at 2 o’clock.
