NGC 3521
NGC 3521 is a flocculent spiral galaxy located in the constellation Leo, about 35 million light-years away. It's known for its "woolly" or "fluffy" appearance, lacking the well-defined spiral arms seen in some galaxies. Instead, it exhibits a patchy, irregular structure with numerous star-forming regions and a luminous center.
Data was acquired from Telescope Live and processed in Pixinsight.
