This galaxy is also known as the Sunflower Galaxy. Imaged from my backyard which was probably about a mag 4 sky the evenings I imaged. Combined with Maxim DL and processed in Photoshop CS. I used many of the ideas from Ron Wodaski's Zone System to pull out some fainter detail. I also used the High Pass filter in Photoshop to create layer masks to emphasize some fine details without decreasing the signal to noise, which is a technique I've seen used by lunar imagers.

As an example of what alot of short exposures can do, here is a display of a single L frame and the combination of all L frames.
