Nebulae & Galaxies
DateNovember 20, 2012
EquipmentOrion ED80T CF Atlas EQ-G Atik 314L+
DescriptionMosaic of NGC1499, 5 panels in HA, OIII and SII with over 48 hours of integration
LocationMistusinne Saskatchewan and urban Calgary Alberta
Date2010 to 2012
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

DescriptionNGC7635,also called the Bubble Nebula is a emission nebula in Cassiopeia,created by the stellar wind from a massiv hot young Wolf-Rayet star(10-40 solar masses).The main bubble is contained within another bubble about 2,5 times the diameter of the smaller and all is embedded in a giant molecular cloud.Distance abt.7800 ly.

EquipmentCelestron 11 f/10. Mount: CGEM DX . Guidescope: sky watcher 80/600. Camera: SBIG 8300 M
Description16 x3' L / 10 x 3' R / 10 x 3' B. Artificial G. It was the first picture I took with the new mount. To note that I live in the center of Rome, in an area with strong light pollution. It is unbelievable what technology can do!

DescriptionSimeis 147, also known as Sharpless 2-240 is a large and extremely faint supernova remnant lying on the border of the Constellations Taurus and Auriga. It is approximately 3000 light years from Earth and covers an area of sky larger than 3x3 degrees. The supernova is estimated to have occurred over 30,000 years ago leaving behind this remnant and a spinning neutron star at its center designated as a pulsar PSR JO538+2817. It was discovered in 1952 in Simeis a then part of the USSR. The narrowband image is a composite of 36 hours of exposure.
