A Triangulum Lookalike
NGC 2403, a spiral galaxy in Camelopardalis, closely mirrors the Triangulum Galaxy (M33) in structure and vigorous star‑forming regions. It resides roughly 8 million light‑years away as part of the nearby M81 galaxy group. Cataloged as Caldwell 7, the galaxy was captured in a 26.6‑hour exposure using an 8‑inch f/4.8 telescope equipped with a one‑shot color camera. The image highlights bright H II complexes that underscore ongoing stellar birth.
