Over the past few months I have been on a mission to achieve a long time dream of mine: Taking a deep sky image with more than 100 hours of exposure!
Now, after having gathered 120 hours of data over 43 different nights in Feb-May 2013, I'm happy to present what appears to be the deepest view ever obtained of Centaurus A. This is likely also the deepest image ever taken with amateur equipment (faintest stars are magnitude 25.45).
