NGC_1499_small.jpg
NGC 1499 California Nebula1030 viewsThe California Nebula (NGC 1499) is an emission nebula located in the constellation Perseus. It is so named because it appears to resemble the outline of the state of California on long exposure photographs. It is almost 2.5° long on the sky and, because of its very low surface brightness, it is extremely difficult to observe visually. It lies at a distance of about 1,000 light years from Earth. This is a Ha, G, B exposure.
Lynds_Dark_Nebula_673.jpg
Lynd's Dark Nebula 673886 viewsLynd’s Dark Nebula 673 is an extensive dust cloud that can be found in the constellation Aquila. Image was taken with a modified Canon 40D DSLR camera (ISO 800) and a Takahashi Epsilon 180 f/2.8 astrograph on a Paramount. Image is a total of 3 hours 30 min exposure (42 x 5 min lights; 20 darks; 64 flats).
M15n=14.jpg
M15 Globular Cluster in Pegasus1138 viewsMessier 15, a gobular cluster in Pegasus, which was originally discovered by Maraldi in 1746 and rediscovered by Messier in 1764, lies 30,600 light years away. Fourteen 120-second exposures aligned, calibrated, and combined in Images Plus; processed with Adobe Photoshop CS2; taken with a 178mm f/9 Astro-Physics refractor and a Canon 20Da DSLR camera (ISO 800).
NGC891.jpg
NGC891536 viewsNGC891 is an unbarred spiral galaxy in the constellation of Andromeda. It is located 30 million light-years from earth and it measures 100 light years across. Astronomers believe NGC891 looks similar to the Milky Way if viewed edge-on. This image consist of 5 hours of exposure with a Canon 60Da camera, 8” TPO RC telescope, and Celestron CGE Pro mount. Processed in PixInsight 1.8.
M95_2012_03_22_6SCT_16IC_32min_SN2012aw.jpg
Supernova in M951033 viewsA Type II supernova recently exploded in M95, a galaxy approximately 33 million light years away. Type II supernova are generated when large massive stars "die" and blow up. Heavier elements such as iron, gold, silver and uranium are created in about a second then scattered into the cosmos. The supernova is still about magnitude 13 so its still pretty dim (given its large distance). Imaged using a 6" SCT at f6.3 using an Atik 16IC camera (32 min exposure).
Messier_81_in_Ursa_Major.jpg
Messier 81 in Ursa Major1234 viewsM 81 is a spiral galaxy in the constellation Ursa Major was discovered by Johann Elert Bode in the 18th century. Current estimates indicate M 81 is approximately 11 million light years away. The dim companion galaxy Holmberg IX (UGC 5336) can be seen as a small blue smudge above M 81. The image was taken with a 130 mm f/8 Astro-Physics refractor with a total combined exposure of 7 hrs 40 minutes (92 x 5 min lights; 30 darks; 64 flats; SBIG ST 2000xcm @ -25 0C; AP 1200 mount)
NGC_2175_Monkey_Head_Nebula.jpg

NGC 2175 is part of Sharpless 2-252, which is an extended H-II region that is approximately 7200 light years away. Please note that there is some discrepancy in the literature as to the designation as NGC 2175 or NGC 2174...for a discussion see S. J. O'Meara in Deep-Sky Companions: Hidden Treasures: Cambridge 2007. Image was taken with a Takahashi Epsilon 180 f/2.8 astrograph and a SBIG STF8300c camera on a Paramount. The exposure was a total of 14 hours 30 min exposure taken on 12/26, 12/27, 12/30 2012 and 1/1, 1/2 2013 (87 x 10 min lights, guided; 20 darks; 64 bias; 61 flats; all at -20 degress C). Images were graded in Images Plus 5.0 and calibrated, registered, integrated, and processed in PixInsight 1.8.1 Ripley.

NGC_4631_RCOSf6_DarkMottleRepFinal_Large.jpg
The Whale Galaxy in Canes Venatici319 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).

IC_443_Large.jpg
Turbulent nature of the Jellyfish Nebula441 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).Jun 30, 2018
