NGC 6910 - RBG-HSO - 2021-07-09
NGC 6910 is an open star cluster set amidst clouds of gas and dust near the bright star Sadr in the constellation Cygnus.
Subframes for this image were accumulated over 4 different nights, some under dark skies near Goldendale, WA and others from within Seattle city limits. RGB data for the stars was combined with narrowband data for the gas and dust, with Ha assigned to R. In an effort to maintain a "natural" appearance, only modest amounts of SII and OIII data were added to the G and B channels, respectively.
Telescope: Celestron EdgeHD 8" with 0.7x Reducer
Camera: QSI 683wsg
Mount: Astro-Physics Mach1 GTO
Integration: 30 min (6 x 5 min) each RGB, binned 1x1 | 300 min (30 x 10 min) Ha, binned 1x1 | 100 min (10 x 10 min) SII, binned 2x2 | 120 min (12 x 10 min) OIII, binned 2x2.
