This dataset captures Heckathorn-Fessen-Gull 1, also catalogued as PK 136+05, through 66.2 hours of total integration time acquired between June and December 2022. The imaging setup employed a Sky-Watcher MN190 telescope paired with a ZWO ASI1600MM Pro camera on a Sky-Watcher EQ6 Pro mount. Narrowband data dominates the collection, with 525 frames through an Antlia 3nm H-alpha filter at 300 seconds each and 251 frames through an Antlia 3nm OIII filter at the same exposure length. Broadband RGB data adds colour information via 45 frames captured with an Astronomik DeepSky RGB filter at 120 seconds per frame.
The dataset is available as a one-time purchase for approximately $32.90 and is released under a CC BY 4.0 license, permitting copying, modification and redistribution with appropriate attribution to the author.
