It took me a while to realize the double triangle mentioned is something I too came across many years ago. It seems every time I look for M104 I see it. It does stand out. I had named it the Corvus wolf as that is how it impressed me. At the time I searched though all my literature, but could find no reference to it. I'm happy to see SAC has it listed now.
