M74 is a galaxy, whose seemingly undisturbed spiral arm can be traced from the center to the outer reaches. But near the center it posesses a star-forming region indicating gravitational influence.
It is fun to work with data containing strong signal.
When I look at my older images I find it always surprising, how few frames were sufficient to create a presentable image:
