NGC 2841 (2025)

This is my version of NGC 2841, a flocculent spiral galaxy located about 50 million light years away in the constellation of Ursa Major. Flocculent refers to a type of spiral galaxy whose arms are puffy and discontinuous. The diameter has been estimated to be between 100,000 and 150,000 light-years in the constellation of Ursa Major making it larger than our own Milky Way. I like how it turned out, especially the dust lanes and flocculent nature of NGC 2841. Another surprise was the rich field full of other galaxies much further away.
