Barnard 150, known as the Running Shadow, is a dark nebula captured here through 17.8 hours of narrowband imaging between September 10 and September 20, 2023. The dataset comprises 535 frames across four filters: 260 red channel exposures at 120 seconds each, 96 blue, 90 green, and 89 luminance frames of identical duration. All data were acquired using a TS-125 APO refractor paired with an ASI294MM Pro monochrome camera on an AM5 mount, with Antlia 1.25-inch filters providing the spectral separation.
This dark nebula presents a challenging target for astrophotographers, requiring substantial integration time to reveal the subtle dust structures against the background star field. The dataset is available as a one-time purchase for approximately $4.90 under a CC BY-NC 4.0 license, permitting copying, modification, and redistribution for non-commercial purposes.
