LDN 1251, known as the Rotten Fish nebula, is a dark molecular cloud captured here over 22.67 hours of total integration between late July and mid-August 2025. The dataset comprises 196 luminance frames and 76 color frames (25 red, 25 green, 26 blue) acquired through Antlia 2-inch filters, each exposed for 300 seconds. Imaging was performed with a Sky-Watcher Esprit 120mm refractor and ZWO ASI2600MM Pro monochrome camera on an AM5 mount.
This dark nebula in Cepheus presents complex dust lanes and subtle nebulosity that benefit from the substantial luminance data. The dataset is available as a one-time purchase at approximately $19.90 under a CC BY-NC 4.0 license, permitting copying, modification and redistribution for non-commercial purposes.
