  1. Thanks Guy, The EON is actually a doublet "apo" chromatic. I use the AstroTech Field Flattner.
  2. I've been trying to knock the rust off the gear (and my processing skills) as it has been another typical Florida summer. This is a reprocess of IC 410 that I collected with the 80mm EON back in 2012. I am hopeful the weather will clear and I'll be back outside in a month... This was imaged using 6 minute exposures for a total of 1 hour 18 minutes in the red, and 1 hour in each the green and blue filter. Fifteen minute exposures were taken through a hydrogen alpha filter for a total of 5 hours and 15 min. integration time. Imaged from Ocala, Florida Processed in Photoshop CS5 Imaging teles

    M106 is a Spiral galaxy in Canes Venatici ~23.7 million light years from Earth. Imaged February 15, 16, 28 and March 2 2014 from Ocala, FL. 1 hour and 6 min each RGB 3 hours and 40 min Luminance 2 hours and 20 min Ha Processed in Photoshop CS5 Imaging camera: QSI 683 wsg-8 Imaging telescope: Astro-Tech 8" Richey-Chretien Losmandy G-11 with Gemini II http://coatesastrophotography.blogspot.com/2014/03/m106.html
  4. Updated composite of Barnard 33, the Horsehead nebula. 12/17, 12/18 and 12/22, 2011 and 1/2, 1/3 2012, Nov. 29, 2013, Nov. 30, 2013, Dec. 7, 2013, Dec. 12, 2013 Emission, reflection and dark nebula ~1,344 light from Earth lacated in the Orion constellation. Ocala, FL Portions of this image has data from the Astro-Tech 8" Ritchey-Chrétien which was used to add more detail to the Horsehead (see http://bit.ly/19HV3hz for details). RGB data: combination of 2 minute and 4 minute exposure stacked in DSS for a total of 5 hours and 2 min 80mm EON RGB data: 50 minute Red, Green and Blue (binned 2x2)
  5. Thanks starman1969, Richard, x6gas and Paul1!
  6. Here is another image from the past week. M81, Bode's galaxy, is a spiral galaxy in the constellation Ursa Major approximately 11.8 million light years from Earth. This is a composite of luminance data imaged from the QSI 683 (2014) and RGB data from a Canon T1i (2011). Imaged from Ocala, FL RGB data: 360 second exposures stacked in DeepSkyStacker and processed in Photoshop for a total integration time of 6 hours and 26 minutes. Luminance data: 360 second exposures totaling 1.6 hours of integration using QSI 683wsg-8. Astro-Tech 6" Richey-Chretien (RGB) Astro-Tech 8" Richey-Chretien (Luminance
  7. This has been a terrible winter here in the south eastern U.S. This is a composite image of M82... M82, with supernova SN 2014J, the Cigar galaxy in Ursa Major is 11.8 million light years from Earth. The galaxy center of M82 is active with high rate of star formation caused by the gravitational effect from nearby spiral galaxy, M81. This is a composite image taken from two different telescopes and two different cameras. The color is from a Canon T1i that was collected in 2011. The QSI 683wsg-8 was used to collect Luminance and Hydrogen-alpha data. RGB data: 360 second exposures stacked in Dee
  8. Just want to share a link to a neat online group of astronomers that share the universe online on Sunday evenings: http://youtu.be/y8DRz7_TW6k
  9. Thanks A.G and Per! Per, I went ahead and did as you suggested and am happy with the results. The stars are from RGB data I had from a DSLR, but those magenta "hues" still poked through, thanks for pointing them out and suggesting the correction. I appreciate your input, Happy Holidays, Steve
  10. The Rosette nebula (aka NGC 2237, NGC 2238, NGC 2239, NGC 2244, NGC 2246) is an emission nebula associated with open clusters of stars located in the constellation of Monoceros, 5,200 light years away. Imaged from Ocala, Florida through Ha, OIII and SII filters and processed using Hubble palette, assigning SII to RED, OIII to BLUE and Ha to GREEN. 20 minute exposures combined to a total of: 3 hours Ha (binned 1x1) 3 hours OIII (binned 1x1) 3 hours SII (binned 1x1) Processed in Photoshop using Hubble palette Imaging telescope: Orion 80mm EON (Focal length 480mm) Imaging camera: QSI 683 wsg-8 Lo
  11. Nicely done Harel! Those photons matured nicely on your hard drive .
