Hydrogen Alpha Image

NGC2264 the Cone Nebula and Christmas Tree Cluster, with NGC2261 Hubble’s Variable Nebula is visible to the south west (lower right) of the image, taken on Jan 24, 2018 from Buford Mountain Conservation Area. It was imaged with a Stellarvue SV80ST with SFFR-6 focal reduce for a focal length of 384 mm, QSI 683wsg-8 camera at -10C, all mounted on a Celestron Advanced VX mount with off-axis guiding. The total exposure time was 3 hours 30 minutes through an Astrodon Ha 3 nm filter.
