Lester,
That'd be M6. The Butterfly Cluster. I love it; it's such a beautiful cluster. That offset red star really does it for me.
Here's my shot
here; it was a single 60-second exposure which I was simply doing for focusing purposes.
Taken through 8" LX90LNT, Canon EOS-350D. Diffraction spikes recreated using 30-pound fishing wire.
