Sh2-206_Supernova_Remnant_in_the_Constellation_Taurus.jpg
Sh2-240 Supernova Remnant in Taurus225 viewsImaged is the large supernova remnant Sharpless 2-240 in the constellation Taurus. The complex filamentary structure leads to it's common name, the Spaghetti Nebula. Field of view of the image is 2.12 x 3.21 degrees that captures only part of the nebula, which is approximately 3 degrees. Emission of the nebula is believed to be due to the shock wave of the expanding gas. Image was captured through a Takahashi FSQ 106ED with focal reducer (f/3.6 fl =385mm) and a Canon 60Da DSLR on an Astro-Physics 1200 mount; 23rd and 27th Oct 2014 (20 x 900 sec lights @-20 degrees, dithered; 35 darks; 126 flats; 128 bias; Software: SkyX, MaxIm DL 6, processed in PixInsight 1.8.3.1123).
IC1848_Soul_Nebula_sRGB.jpg
The Soul Nebula 224 viewsThe emission nebula Sharpless 2-199 and the open cluster IC 1848 in the constellation Cassiopeia are commonly referred to as the soul nebula. The emission nebula is a massive star-forming region. The image was a total combined exposure of 8 hr 45 min taken over 6 nights (Aug and Oct 2014) in Mayhill, NM (35 x 900 sec lights at -20 degrees, dithered; 35 darks, 128 bias, 128 flats); Takahashi Epsilon 180 f/2.8 astrograph; Paramount ME; SBIG STF 8300c; guided with a ST-i camera and an Astro-Physics/Baader guider system; acquisition with MaxIm DL 6; Images calibrated, aligned, integrated, and processed in PixInsight 1.8.4 using a Synthetic Luminance and Multiscale Processing.
M46M47NGC2423inPuppis.jpg
Open Clusters M 46, M47, and NGC 2423 in Puppis224 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.
CrescentNebula.jpg
The Crescent Nebula in Cygnus220 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).

An Open Cluster and Nebula in the constellation Auriga161 viewsNGC 1931 is a relatively young open cluster surrounded by emission and reflection nebulosity (Sharpless 2-237) in the constellation Auriga. Faint red hydrogen emission can be see in the region surrounding the compact cluster/nebulosity. Sharpless 2-237 shows both red hydrogen emission and blue reflection nebulosity. Image was a total of 15 hours of exposure through a Takahashi CCA250 f/5 astrograph with a QSI683wsg camera @ -20 degrees C. (Astrodon Gen 2 filters) on a Paramount ME on the nights of 23, 30 Nov and 5 Dec 2016 and 13, 18, 19 Jan 2018 in Mayhill, NM (Lum 30 x 1200 sec; Red 5 x 1200 sec; Green 5 x 1200 sec; Blue 5 x 1200 sec; with corresponding Flats, Darks, and Bias). Processed in PixInsight 1.8.5.1353 Ripley (x64). Color calibration and RGB image stretch with PixInsight's Photometric Color Calibration and Arcsinh Stretch, respectively.
IC_443_Large.jpg
Turbulent nature of the Jellyfish Nebula8 viewsFound in the constellation Gemini, the Jellyfish Nebula, also designated IC 443, is a large supernova remnant. The emission of the nebula is due to the excitation of hydrogen atoms as the rapidly expanding shell collides with the surrounding molecular gas. This hydrogen-alpha image shows the turbulent nature of the nebula as the resultant shock wave expands. Image taken with a Takahashi CCA-250 f/5 astrograph and QSI683wsg CCD camera (Astrodon 5nm H-alpha filter) on a Paramount ME in Mayhill, NM on the nights of the 23rd, 24th January 2018. Total of 7 hr exposure (21 x 1200 sec lights @ -20 degrees C; 24 darks; 128 bias; 128 flats). Processed in PixInsight 1.8.5.1353 Ripley (x 64).
NGC_4631_RCOSf6_DarkMottleRepFinal_Large.jpg
The Whale Galaxy in Canes Venatici2 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). Total of 5 hr 40 min exposure taken with an SBIG STF8300c CCD camera and a 12.5 inch RCOS f/9 astrograph operating at f/6 (Astro-Physics CCDT067 reducer) mounted on a Paramount ME on the nights of 8, 15, 16 May 2018 in Mayhill, New Mexico (17 x 1200 sec Lights @ -15 degrees C; 15 darks; 128 bias; 128 flats). Processed with PixInsight 1.8.5.1353 Ripley (x64).
