M94
Here is a picture of spiral galaxy M94. This is a spiral galaxy about 16 million light years away in the constellation of Canes Venatici. It is notable for having two ring structures. The inner ring is a site of strong star formation known as the starburst ring. The outer ring is a complex structure of spiral arms.

Thanks Steve and Charles. The core was indeed a challenge. Adam Block has a DVD on CCDStack that had a procedure for merging long and short duration exposures that really helped.

Excellent work from the well resolved core to the faint outer bands. A lot went into this image and it shows in your processing.
