This dataset captures NGC 6888, the Crescent Nebula, an emission nebula in Cygnus formed by stellar winds from a Wolf-Rayet star. The data comprises 14.5 hours of total integration collected between June 13 and 2026, using a William Optics Minicat51 Wifd telescope paired with a ZWO ASI2600MC Air camera on a ZWO AM3 mount. The acquisition includes 290 frames split across two narrowband filter combinations: 90 frames through Svbony sv220 SII OIII and 200 frames through Svbony sv220 Ha OIII, all at 180-second exposures. This dual-filter approach isolates ionized sulfur, hydrogen, and oxygen emissions, revealing the nebula's shock-front structure and intricate filaments.
