This dataset captures the Propeller Nebula (DWB 111, also catalogued as Simeis 57) through 22.3 hours of total integration time collected between late July and late August 2024. The imaging setup employed a TS-130 APO refractor paired with an ASI294MM Pro monochrome camera on an AM5 mount. Narrowband data forms the core of the acquisition, with 105 frames through Antlia 3nm H-alpha (300 seconds each), 87 frames in OIII, and 58 frames in SII, all using the same exposure duration. RGB broadband data supplements this with 60 frames per channel at 30 seconds each through Antlia Red, Green, and Blue filters. All filters share a 1.25 inch format. The data is offered under a CC BY-NC 4.0 license for approximately $17.90, permitting copying, modification, and redistribution for non-commercial purposes only.
