This Omicron Cygni dataset comprises 55.85 hours of integration captured between May 25 and June 16, 2026, using an Askar 71F telescope paired with a ZWO ASI 533MC Pro camera on an AM3 mount. The collection includes 899 frames through an Optolong L-Extreme HA-OIII 7nm filter and 218 frames through an Optolong L-Quad Enhance filter, all at 180-second exposures. This dual-filter approach provides both narrowband hydrogen-alpha and oxygen-III data alongside enhanced broadband coverage, offering flexibility for processing emission nebulae and surrounding stellar fields in this region of Cygnus. The data is available as a one-time purchase for approximately $4.90 under a CC BY-NC 4.0 license, permitting copying, modification, and non-commercial redistribution.
