Description

Taken over two dark nights with a waxing crescent moon August 18 and 19, 2023 using a 34-year old Nikon Micro 105mm f/2.8 AI-s lens and ASI2294MC camera.  Lens aperture stopped down 2 steps to f/5.6 and ASI camera rotated roughly 90° counter-clockwise to frame the target (Gamma Cygnic nebula).   Resolution of final image is 9.2 arcsec/pixel.  45 narrowband frames collected using Optolong L-Extreme filter (first night) and 13 broadband frames (for stars) collected using UV-IR Cut filter.   Exposure for all frames is 300s.   Full-width-half-maximum (FWHM) of stars is 1.213 pixels and eccentricity (Ec) is 40%.
