NGC6888_CrescentNebula_Royce_5X500s_Aug_21_2014_XLogLogLog_CS6crop
NGC6888, called the Crescent Nebula, is barely visible in this RGB color image, taken Aug 21 2014, with a 10" Royce Newtonian FL 1524mm Diam 254mm f/6, at Sunnyvale, California (backyard). Imaged with an Orion Starshoot Pro (V1) Camera, Baader MPCC coma corrector, and a Schneider 486 UVIR Filter. This is a stack of 5 images of 500sec each. The final image was stacked in personally developed software, then stretched with the log(log{log[]}) function, and adjusted in Photoshop CS5 for color balance. The corresponding Halpha light at 656nm is an another image (should be next to this one), and that image shows the nebular gas more clearly.
