Messier 74, with and without supernova SN 2013ej

Above is an animation showing the supernova SN 2013ej in Messier 74 blinking: it compares a recent shot with an archive frame, dating back in 2012. The effect is spectacular: the SN seems to jump out ot the screen!

Below is a good signal-to-noise low-res spectrum, taken last night with the Celestron c14 robotic unit: H-alpha is now very well visible with its sharp emission line.
