This image was taken June and July 2015, with 20.2 hours total exposure time, 12.2 LRGB (6 minute sub exposures), and an additional 8 hours (15 minute sub exposures) of Ha data for the outer red "petals". Taken with my Paramount MX mount and AG Optical Systems 14.5" iDK telescope, with a ST-10XME camera. This is my first image with the AG Optical Systems telescope.
