M51, The Whirlpool Galaxy

I took few images during near full moon (90+ percent) of this famous galaxy. I didn't had any big expectations of the result because of the moon phase and short exposure time. But the final image surprised me!

Here's only 2h 50min of exposure:
                                             L        =   4 * 1200"
                                             RG     =   3 * 300"
                                             B        =   6 * 300"
                                             Ha      =   3 * 600"
