This dataset captures LDN 1399, also known as Barnard 11, a dark nebula complex in the Taurus molecular cloud, alongside the faint supernova remnant G150.3+4.5. The collection spans 37.6 hours of total integration acquired between September and December 2025 using a Sky-Watcher Esprit 120mm refractor and ZWO ASI2600MM Pro camera on an AM5 mount. The data comprises 72 luminance frames at 300 seconds each, 30 frames in each RGB channel, and deep narrowband coverage with 158 H-alpha and 131 OIII frames, all through Antlia 2-inch filters. This combination of broadband and narrowband data enables detailed mapping of both the obscuring dust lanes of the dark nebula and the tenuous emission structures of the ancient supernova remnant. The dataset is released under CC0 1.0 Universal, placing it in the public domain, and is available for approximately $24.90 as a one-time purchase.
