Narrowband image of the Crescent Nebula in Cygnus372 viewsThe Crescent Nebula (NGC 6888) is found in the constellation Cygnus, whose emission is powered by strong stellar winds from a Wolf-Rayet star colliding with previously expelled outer envelopes of the stars atmosphere. This narrow band image is a combination of 5 hrs of H alpha data (Astrodon 5 nm Gen 2 filter) and 5 hrs 20 m of O[III] data (Astrodon 3 nm Gen 2 filter). Taken with a Takahashi CCA-250 f/5 astrograph and QSI683wsg camera on a Paramount ME; August 11th , 13th and Sept 14th - 17th, 2015 in Mayhill, NM (Ha, 15 x 1200 sec lights @ -20o C; O[III], 16 x 1200 sec lights @ -20o C 21 darks; 126 bias; 128 flats) Image acquisition with MaxIm DL 6.08; Calibrated, aligned, integrated, and processed in PixInsight 1.8.4.1185 Ripley (x64); Colors assigned ( Red = Ha, Green = 15% Ha + 85% O[III], Blue = O[III] ) and combined using SHO-AIP script.

M95_2012_03_22_6SCT_16IC_32min_SN2012aw.jpg
Supernova in M95840 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).
Vega_Betelgeuse_spectra.jpg
A Tale of Two Stars958 viewsHere are basic spectra from two familiar stars in the night sky. Vega's spectra is on the left and basically has weak spectral lines based mostly on the Hydrogen Balmer series. This is indicative of a fairly young, hot star. Betelgeuse's spectra is far more complex. We can see spectral lines for Barium, Calcium, Iron and Magnesium and compounds like Vandium Oxide and Titanium Oxide indicative of a star near the end of its life. Data collected with amateur equipment and processed through RSpec software.
NGC_246.jpg
NGC 246 (The Skull Nebula)418 viewsNGC 246 is a small planetary nebula in the constellation of Cetus. The nebula was discovered in 1785 by William Herschel and gets its nickname due to its resemblance to a human skull. NGC246’s central star, is a white dwarf that is entering its final phase of evolution becoming a hot white dwarf. This image was taken on Oct 23, 2016 with an 8" TPO RC telescope, Canon 60Da camera, on a Celestron CGE Pro mount. Stacked with Nebulosity 4 and edited with PixInsight 1.8

NGC663FinalsRGB_Large.jpg
Open Cluster in Cassiopeia 43 viewsThe open cluster NGC 663 is found in the constellation Cassiopeia. NGC 663 contains a significant number of Be stars (spectral class B stars showing emission lines in their spectra). The distance from us is on the order of 2,100 parsecs (6850 light years). The image is a total of 5 hrs 20 min exposure taken with a 12.5” RCOS f/9 @ f/6 (Astro-Physics CCDT67) and SBIG STF8300m camera on a Paramount ME in Mayhill, NM on the nights of 28 Nov and 3 Dec, 2018 (6 x 1200 sec R; 5 x 1200 sec G & B; 24 darks; 128 bias; 128 flats).

NGC4565Large.jpg
An Edge-On Spiral Galaxy in Coma Berenices82 viewsNGC 4565, sometimes referred to as the Needle Galaxy, is an edge-on galaxy in the constellation Coma Berenices. One can see the galaxy's yellowish central core, which is divided by obscuring dust lanes running the length of the equatorial plane.

NGC_4631_RCOSf6_DarkMottleRepFinal_Large.jpg
The Whale Galaxy in Canes Venatici114 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 Nebula172 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
