IC 4685 was captured over 18.75 hours of total integration between June and September 2024, using a TS-130 APO refractor and ASI294MM Pro camera on an AM5 mount. The dataset comprises 225 narrowband frames: 96 exposures through an Antlia 3nm H-alpha filter, 66 through OIII, and 63 through SII, all at 300 seconds each. This tri-band narrowband approach isolates emission from ionized hydrogen, oxygen, and sulfur, revealing the nebula's structure and chemical composition. The data is available as a one-time purchase for approximately $9.90 under a CC BY-NC 4.0 license, permitting copying, modification, and redistribution for non-commercial purposes.
