NGC 6888 Emission Nebula in Cygnus. Taken June 15 and 16, 2007 with a DSI Pro II and Outback Cooler
on a C80ED operating at f7.5. RGB subframes were 120 sec while the H-alpha subframes were 360 sec.
resulting in the following total exposures Ha:Ha+R:G:B (min) = 204:204+72:78:68. Color balance was
achieved via numerically scaled channels. Captured with Envisage, calibrated and sigma combined in
Iris with other processing using FITZ, PixInsight LE and Photoshop CS. North is up.
