Description

It's been a while since I uploaded our galaxy images, so there is a backlog. Here is another one. This is a difficult target with a very bright core and very dim outer halo. It took 30 hours of subs in order to fully bring out that outer faint ring. Here is a better description of M94 taken directly from the Wikipedia."

"M94 contains both an inner ring with a diameter of 70" and an outer ring with a diameter of 600". These rings appear to form at resonance locations within the disk of the galaxy. The inner ring is the site of strong star formation activity and is sometimes referred to as a starburst ring. This star formation is fueled by gas that is dynamically driven into the ring by the inner oval-shaped bar-like structure."
