This is so funny Suavi, last night when I made my quick decision to go out to my observatory I was contemplating what to image as I was driving out and one of the things I thought was "I should do a couple of hours of Ha on Cen A and add it to my latest effort on the galaxy, that might be interesting?" ...and today you post this!
Great idea, have you got an LRGB to add this to?
