California_Nebula__NGC_1499.jpg
The California Nebula822 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.
Messier82_sRGB.jpg
The starburst galaxy Messier 82701 viewsThis HaLRGB image portrays the turbulent starburst galaxy Messier 82 in Ursa Major with its filamentary outflows of ionized hydrogen. This emission is suggested to be due to stellar winds caused by massive energetic young stars (as well as supernovae resulting from their death) being born at a high rate within the galaxy. Total of 18 hrs exposure with a Takahashi CCA-250 f/5 astrograph; Nights of 15, 24, 28 March 2015; 12, 13 Jan 2016; 8, 9 Feb 2016: 2015 Paramount ME, QSI683wsg, Astrodon Gen2 filters (Ha 5 nm); (Lum 16 x 20 min; Ha 17 x 20 min; R 7 x 20 min; G 7 x 20 min; B 7 x 29 min all @ - 20 degrees C), calibrated, registered, integrated, and processed in PixInsight 1.8.4.1195 (x 64).
CrescentNebula.jpg
The Crescent Nebula in Cygnus628 viewsThe Crescent Nebula (NGC 6888) is an emission nebula found in the constellation Cygnus. A leading hypothesis suggests that the strong stellar winds from the central Wolf-Rayet star collides with the stars outer atmospheric envelope ejected in a previous evolutionary phase, which energizes the nebula and leads to the observed structure. This H alpha image is a total of 5 hours of exposure taken with a Takahashi CCA-250 f/5 astrograph and QSI683wsg camera (Astrodon 5 nm Ha filter) on a Paramount ME; August 11th , 13th 2015 in Mayhill, NM (15 x 1200 sec lights @ -20o C; 21 darks; 126 bias; 128 flats) Image acquisition MaxIm DL 6.08; Calibration, alignment, integration, and processing in PixInsight 1.8.4.1107 Ripley (x64).
IC_1805_in_Cassiopeia.jpg
The IC 1805 region941 views IC 1805 is a bright heart-shaped emission nebula in the constellation Cassiopeia. The open cluster in the center of IC 1805 is Melotte 15 that contains several extremely large stars whose intense radiation ionizes the hydrogen gas in the region. To the lower left of IC 1805 is the bright nebula NGC 896. To the mid-right of IC 1805 is the open cluster NGC 1027. The image encompasses a vast region with the image scale being approximately 3.1 x 2 degrees.
The image was taken with a Canon 60Da DSLR (ISO 800) and a Takahashi FSQ 106ED with focal reducer (f/3.6; focal length = 385 mm) on an Astro-Physics 1200 mount. Image was a total of 6 hours 15 minutes exposure [75 x 300 sec lights (guided with a Takahashi Mewlon 300/SBIG ST-i); 12 darks; 128 bias; 64 flats]. Images selected (SubframeSelector), calibrated (using a “superbias” master), registered, integrated, and processed in PixInsight 1.8.3.1115.

NGC_4631_RCOSf6_DarkMottleRepFinal_Large.jpg
The Whale Galaxy in Canes Venatici514 viewsNGC 4631 is found in the constellation Canes Venatici. The wedge-shape of this galaxy gives rise to its nickname, the Whale Galaxy. The starburst regions of this galaxy can be seen in the photo, which are due to intensive star formation. Tidal interactions of NGC 4627, which is seen just above NGC 4631, has been suggested as one of the reasons for the active core of NGC 4631 (as well as tidal interactions with other nearby galaxies). The small edge-on galaxy at the top of the image is PGC 3794315 (NASA Extragalactic Database).

IC_443_Large.jpg
Turbulent nature of the Jellyfish Nebula689 viewsFound in the constellation Gemini, the Jellyfish Nebula, also designated IC 443, is a large supernova remnant.
