M78_contrast_Labels_noCircles.jpg
Messier 78 and neighbors953 viewsMessier 78 is a diffuse reflection nebula located in the constellation of Orion. The starlight bounces off the dust particles in the nebula which create the bright reflection areas. The dark area that separates M78 from NGC 2067 consist of obscuring dust that blocks the light from background stars. The image consist of over 10 hours of data (128 x 5min exposures) taken with a Canon 60Da camera, TPO RC telescope on a Celestron CGEM mount. Stacked with nebulosity and processed with Photo Shop CS6.
NGC_891_in_Andromeda.jpg
NGC 891 in Andromeda1107 viewsNGC 891 is an edge-on spiral galaxy found in the constellation Andromeda. Current estimates put NGC 891 30 to 31 million light-years away from us. A prominent dust lane can be easily seen in the galaxy. Numerous other small galaxies can be seen in the background including a faint galaxy to the right of the central bulge. Image was a total of 8 hrs of combined exposure taken over 6 nights (32 x 15 min lights @ -20 degrees C, dithered; 32 darks; 128 bias; 128 flats) taken with a TeleVue 140 f/5 refractor and SBIG ST2000xcm camera on an Astro-Physics 1200 mount. Image acquisition and guiding with MaxIm DL 6.07 and image calibration, registration, integration, and processing with PixInsight 1.8.3.1123 Ripley (x64).
California_Nebula__NGC_1499.jpg
The California Nebula926 viewsNGC 1499, aka the California Nebula, is a large emission nebula in Perseus. It is about 2.5 degrees in length and has a very low surface brightness, which makes it somewhat of a challenge to observe visually. The image was taken with a Canon 60Da DSLR and a Takahashi FSQ106ED telescope with focal reducer (f/3.6 FL = 385 mm) on an Astro-Physics 1200 mount. Total combined exposure was 5 hrs (20 x 15 min guided and dithered lights; 12 darks; 128 bias; 64 flats) taken over three nights (Oct 23rd , 27th , 28th 2014). Image acquisition with MaxIm DL6.07 and calibration, registration, and integration with PixInsight; processing with PixInsight 1.8.3.1123 Ripley (x64) and Adobe Photoshop CC.
ASIC410.jpg
IC 410 and the Tadpoles in Ha756 viewsThe emission nebula IC 410 and the embedded open star cluster NGC 1893 are found in the constellation Auriga. The emission of IC 410, which is about 12,000 light-years away, is powered by the young hot stars in NGC 1893. The gas streamers just to the right and above center, often called the “Tadpoles”, are moving away from the center of the nebula. The image is a Ha image, which shows the extent of the hydrogen emission in the region. The image was taken with a Takahashi CCA-250 astrograph and the QSI683wsg camera (SBIG ST-i guider) on a Paramount ME. The image is a total of 8 hours exposure (24 x 20 min lights @ -20 degrees C, dithered; 21 darks; 126 bias; 128 flats), acquired with MaxIm DL 6.07, and processed with PixInsight 1.8.3.1123 Ripley (x64). Ha filter was an 5nm bandwidth 31 mm Astrodon Gen 2 filter.

Emission nebula IC 410 and the Tadpoles in HaRGB781 viewsThe emission nebula IC 410 and the embedded open star cluster NGC 1893 are found in the constellation Auriga. The emission of IC 410, which is about 12,000 light-years away, is powered by the young hot stars in NGC 1893. The gas streamers just to the right and above center, often called the “Tadpoles”, are moving away from the center of the nebula. Picture is a HaRGB image taken with a Takahashi CCA-250 f/5 astrograph and a QSI683wsg camera (SBIG ST-i guider) on a Paramount ME. The Ha channel (used as Luminance) was blended with the RGB synthetic luminance (80:20, respectively) to give a more natural star color (Pixel Math). The image is a total of 11 hours exposure (24 x 20 min Ha, 3 x 20 min each R,G, and B, all binned 1x1 @ -20 degrees C, dithered;), acquired with MaxIm DL 6.07, and processed with PixInsight 1.8.3.1123 Ripley (x64). Ha filter (5nm bandwidth), R, G, and B were 31 mm Astrodon Gen2 filters.

IC2177 and NGC2327946 viewsIC2177 is a large diffuse nebula near the constellations of Monoceros and Canis Major. The sweeping arc forms the seagull’s wings while the head consist of NGC 2327 (also call the Parrot nebula). This image consist of 80 x 300sec images taken with a Canon 60Da, Orion ED80T refractor, and a Celestron CGEM Mount. Stacked in Nebulosity and processed with PhotoShop CS6
NGC_6992_and_NGC_6995.jpg
NGC 6995 and NGC 6992 (The Eastern Veil Nebula)901 viewsNGC 6995 / NGC 6992 (Eastern Veil Nebula) form part of the Cygnus loop a supernova remnant in the constellation of Cygnus. Other objects that form part of the Cygnus loop, not visible in this image, are NGC 6960 and NGC 6979. The cloud of ionized gas and dust covers an area of 3 degrees (around 6 times the size of the full moon) and continues to expand. The image consist of 44 x 300sec exposures taken with a QHY10 CCD camera and Orion 80mm refractor mounted on a Celestron CGEM mount.
M46M47NGC2423inPuppis.jpg
Open Clusters M 46, M47, and NGC 2423 in Puppis694 viewsThe open clusters Messier 46, Messier 47, and NGC 2423 are found in the constellation Puppis embedded in a rich field of Milky Way stars. The small planetary nebula NGC 2438 that appears to be in M 46 is actually not associated with the cluster. M 46 was discovered by Messier in 1771. Smyth describes it as a “A noble, but rather loose assemblage of stars” (Smyth and Chambers, A Cycle of Celestial Objects, 2nd Edition, 1881, Oxford) whereas Webb describes it as a “Beautiful circular cloud of small stars” (Webb, Celestial Objects for Common Telescopes, 4th Ed, 1881, Longmans, Green, and Co ). William Herschel observed the small planetary nebula NGC 2438 in 1786. M 47 was also discovered by Messier in 1771 but not intermediately attributed to Messier due to a mathematical mistake in his coordinates. The cluster was described by Smyth as “a very splendid field of of large and small stars” (under the entry 38 H VIII) and Webb as a “Grand broad group, visible to the naked eye”. This wide field picture was taken with a Takahashi FSQ106ED with focal reducer (f/3.6), Canon 60Da DSLR camera (2.32 arcsec/pixel), and an Astro-Physics 1200 mount on 15 March 2015 in Mayhill, NM.. Total exposure of 1 hour (4 x 15 min lights, dithered; 12 darks; 128 bias; 64 flats); Baader/Astro-Physics guider system; Image acquisition with MaxIm DL; Calibration, alignment, integration, and image processing with PixInsight 1.8.3.1123.
