An Open Cluster and Nebula in the constellation Auriga432 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.
Galaxies_in_the_Constellations_Virgo_and_Coma_Berenices.jpg
Galaxies in Virgo and Coma Berenices1072 viewsMany galaxies are seen in the constellations Virgo and Coma Berenices. To the bottom left is seen the spiral galaxy Messier 88, in which young stars and active star formation are present. In the lower right corner is seen the elliptical galaxy Messier 87, whose golden brown coloration is suggestive of old stars and little if any star formation. In the upper right hand quadrant is a pair of galaxies, NGC 4438 and 4435, aka the Eyes or Arp 120. Exposure is a total of 13 hr 35 min (163 X 5 min).

Mare Nectaris/Theophilus crater922 viewsThe Sea of Nectar (Mare Nectaris) is a small lunar mare located on the eastern edge of the Moon. Theophilus is the prominent lunar impact crater that lies slightly off center of the image to the left. Theophilus is over 60 miles in diameter and is 14,000 feet deep. The small crater in Nectaris near the top of the image is Rosse and is only 7 miles across. Image taken with a 6" SCT at f20 using a DMK 41AU02 camera through a Lumicom 656 nm filter.

NGC6910_L.jpg
A Young Open Cluster in a Nebulous Complex 557 viewsThe open cluster NGC 6910 is found in the nebulous emission complex IC 1318, which is located in the constellation Cygnus. As NGC 6910 is near the galactic plane, there is a significant amount of interstellar dust in the area. Indeed, the blue spectroscopic star HIP 100548 (aka SAO 49563) is rendered yellowish white due to the light scattering by the interstellar dust. Estimated distance of the star cluster and nebula is 2,000 to 5,000 light years. Image was taken with a 12.5 inch at f/9 RCOS astrograph with a SBIG STF8300c CCD camera on a Paramount ME in Mayhill, NM on the nights of 4, 5, 21, 25, 29, ant 30 Oct 2016. Total of 14 hr 20 min exposure (43 x 1200 sec lights at -15 degrees C; 18 darks; 128 bias; 128 flats); image acquisition MaxIm DL 6; calibration, registration, integration, and processing in PixInsight 1.8.4.1195 Ripley (x64)
NGC_6820_and_6823.jpg
NGC 6820 and 6823791 viewsNGC 6823 is an open cluster in Vulpecula, whose center contains 9th magnitude stars along with fainter members that is immersed in the faint emission nebula NGC 6820. Photographed with a Takahashi Epsilon 180 f/2.8 and Canon 20Da DSLR on a Paramount (Ten 5-minute exposures at ISO 800; calibrated, aligned, combined and processed in Images Plus V 3.80 (DDP stretch) followed by Adobe Photoshop CS4).

NGC1275final_Large.jpg
The Perseus Cluster of Galaxies93 viewsThis image of the Perseus cluster of galaxies, also known as Abell 426, is centered on NGC 1275. NGC 1275 is a giant elliptical galaxy, which is a radio source and x-ray emitter. Abell 426 is part of the Pisces-Perseus supercluster, which contains over a thousand galaxies. The image is a total of 9 hrs exposure with a Takahashi CCA-250 f/5 astrograph and a QSI683wsg camera (Astrodon Gen2 filters) on a Paramount ME taken on the nights of 7 Nov, 3, 13 Dec 2018 in Mayhill, NM (18 x 1200 sec lights; 3 x 1200 sec R, G, and B at -20 degrees; 24 darks; 128 flats; 128 bias).

Open Cluster in Cassiopeia 96 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).

NGC4565Large.jpg
An Edge-On Spiral Galaxy in Coma Berenices134 viewsNGC 4565, sometimes referred to as the Needle Galaxy, is an edge-on galaxy in the constellation Coma Berenices.

NGC_4631_RCOSf6_DarkMottleRepFinal_Large.jpg
The Whale Galaxy in Canes Venatici166 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 Nebula234 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
