The Cone Nebula and Christmas Tree cluster (NGC2264) - 34.5 hours total exposure, about half Ha and the rest RGB. Taken over many nights in Oct/Nov 2011. Have been collecting data for a 6-panel mosaic, including the Rosette nebula, but won't be done in time for XMAS. FSQ-106EDX at 530mm focal length (f/5.0) focused via FocusMax and RoboFocus, STL-11000M camera with Custom Scientific HaRGB filters, Astrodon MMOAG and RGH for off-axis guiding. Happy Holidays from Sierra Skies Observatory!
