EquipmentTelescope/Mount: Celestron Compustar C14 with Astro Physics 0.75x focal reducer (f/8.3). Camera: SBIG STL 11000M with Baader Planetarium H-alpha,L,R,G,B filters. Exposures: H-alphaLRGB=240:235:130:130:130 minutes=14:hours:25minutes total exposure.
DescriptionThe Crescent Nebula (NGC 6888, Caldwell 27, Sharpless 105) is an emission nebula that lies 5000 light-years from Earth in a crowded region of the Cygnus Milky Way. The nebula arises from the bright star near the center of the image, which is the Wolf-Rayet star WR 136 (HD192163). Wolf-Rayet stars are massive, extremely hot stars which throw off tremendous amounts of mass in the form of stellar winds at high velocities near the end of their lives. The nebula forms because this material is colliding with slower moving stellar winds ejected 400,000 years earlier during the stars red giant phase, creating a shock wave, high temperatures, and spectral emission lines. This image includes H-alpha data that provides much more detail than an LRGB image. Compare and contrast this image with the LRGB I posted in 2011.

DescriptionIC 443, the Jellyfish Nebula, is a supernova remnant, in the constellation Gemini, that occurred about 7500 years ago. It is one of the best studied cases of supernova remnants, interacting with surrounding molecular clouds. IC 443 is at an estimated distance of 5,000 light-years. The large nebula, to the left and to the top of the image, is the emission nebula Sh2-249... at a distance of approximately 5200 light years.

EquipmentAstro Tech RC 8" and Celestron SCT 8" scopes, "tuned" SkyWatcher HEQ5 mount, imaging and guide cameras are Point Grey Research Grasshopper 16 bit FireWire cameras, Astro IIDC used for guiding, image capture and processing. The inset Galaxies were shot at 1200 mm (SCT with Focal Reducer) to 1600 mm (RC8" Prime Focus) focal lengths, then reduced by 25% to fit on the page - so the insets are all close to the same relative scale for comparison. The M33 background image was shot at 1600 mm focal length and was actual size. Exposure times were usually 16 minutes luma binned 1x1 and then 4 minutes Red, 4 minutes Green, 5 minutes Blue binned 2x2. This collage represents about 31 hours of actual imaging time on the scope. I have a much higher resolution Tiff (39.1 megabytes) or PNG (18.5 megabytes ) version (4200 x 3302 pixels) which prints off at 300 DPI onto 14" x 11" paper which may be useful if you would decide to print it in the magazine. I have given these out as poster sized Christmas gifts to friend and family
DescriptionThe background is M33 northern core area with 13 inset images of other Galaxies which are 3 million to 300 million light years away. From top to bottom, left to right we have: Top Row: M51, NGC4565, M82 Upper Middle Row: NGC6946, NGC2903 Lower Middle Row: M65, M64, Stephan's Quintet Bottom Row: NGC891, NGC7640, M66, NGC7331 and M81
