The NGC6888 "Crescent" Nebula in Cygnus with ZWO Duoband under the Moon (phase=~0.5)
Photo description / processing
The NGC6888 "Crescent" Nebula in Cygnus, captured with a ZWO Duoband filter almost at dawn with the Moon (phase=~0.5).
Low integration and a bright background did not allow the oxygen rim to be brought out, but showed hints of it. That is, the filter works and I like how it renders the stars, it leaves some color, not completely extinguishing it like 7nm narrowband filters.
Captured with an SV705C camera on a C6N+CG5GT telescope, guided with T7M+30F4. Exposure 1830sec (30 min, 60x30 sec), Unity Gain 252, offset=20,t=+15.
Imaging in EAA mode in SharpCap Pro.
Processing: Siril+StarNet++.
Imaging location: Puschino, Chuvashia, MPC: M12 Puschino
