NGC_6882_NGC_6885.jpg
Open Clusters in Vulpecula381 viewsNGC 6882 /NGC 6885 are open clusters in the constellation Vulpecula, although there is considerable discussion in the literature as to whether one is superimposed on the other, are separate clusters, or if they where accidentally duplicated in the original 1784 observation. The bright foreground star, 20 Vulpeculae, does not belong to the cluster. The image taken with a 12.5” RCOS f/9 astrograph and a SBIG STF8300c camera on a Paramount ME on Oct 2, 2016 in Mayhill, NM (5 x 1200 sec lights @ -15 degrees C; 18 darks; 128 bias; 128 flats). Calibrated, registered, integrated, and processed in PixInsight 1.8.4.1195 Ripley (x64).
NGC_2175_Monkey_Head_Nebula.jpg
The Monkey Head Nebula505 viewsNGC 2175, aka the Monkey Head Nebula, is found in the constellation Orion. 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.
NGC1931TheFlyLuminance.jpg
An Open Cluster and Nebulous Region in Auriga265 viewsNGC 1931, sometimes called “the fly”, is a relatively young open cluster surrounded by a field of nebulosity located in the constellation Auriga. The open cluster is approximately 7000 light-years distant. The image was taken through a Astrodon luminance filter (Gen2) with a QSI683wsg CCD camera and a Takahashi CCA250 f/5 astrograph on a Paramount ME on the nights of 23, 30 November and 5 December 2016 in Mayhill, NM (30 x 1200 sec Lights @ -20 degrees C.; 18 darks; 128 bias, 128 flats). Processed in PixInsight 1.8.5.1353 Ripley (x64).
M17_Hubble_post.jpg
M17 in narrowband (Hubble palette)319 viewsMessier 17 also known as the Swan Nebula or Omega nebula is located in the constellation of Sagittarius. The Nebula is composed mainly of ionized hydrogen. It is around 5,000 light years away from Earth and is one of the most massive star forming regions in the Milky Way galaxy. This false color image utilizes the Hubble palette that maps Ha to green, OIII to blue, and SII to red. Once the images from each filter are combined it creates an interesting photo. This was my first serious attempt at narrowband imaging and hopefully it will improve. The image consist of around 180 minutes of data from each filter.

Messier_78_region_in_the_constellation_Orion.jpg
Dust lanes around Messier 781688 viewsMessier 78 is a reflection nebula in the constellation Orion. As the name “reflection nebula” implies, M78 shines by the reflection of light from surrounding stars. Long photographic exposures show the dust lanes that are near the nebula. The red area in the lower right hand corner of the photograph is part of Barnard’s loop.... a large loop of excited hydrogen gas. Total combined exposure of 11.5 hours (138 x 5 min lights, 35 darks, 64 flats, 64 flat darks); Takahashi E-180ED astrograph; Canon 40D modified.

Conen_Nebula.jpg
NGC 2264327 viewsNGC 2264 in the constellation of Monoceros consists of the Cone Nebula and the Christmas Tree Cluster. The Cone Nebula is an H II region and a dark absorption nebula. The Christmas Tree cluster (upside down) is the open cluster above the nebula. The bright star towards the top center (S Mon) represents the center of the trunk while HD 47887 above the cone nebula, represents the top. Not officially part of NGC 2264 is the Fox Fur Nebula, the blue and red furry like area next to S Mon. 200 min total exposure.

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).Jul 13, 2018
IC_443_Large.jpg
Turbulent nature of the Jellyfish Nebula7 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
RGB_Lum_NonLinearCombination_final_Large.jpg
An Open Cluster and Nebula in the constellation Auriga160 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.Mar 30, 2018

The edge-on galaxy NGC 891 in Andromeda 251 viewsThe edge-on galaxy NGC 891 is found in the constellation Andromeda. NGC 891 is approximately 30 million light-years away and is similar in size to our own Milky Way galaxy. A prominent dust lane is seen in the plane of the galaxy with tendrils of dust seen above and below that plain. These dust tendrils may be due in part to supernova explosions. The image is a total of 11 hours of exposure through a 12.5 inch f/9 RCOS astrograph with a SBIG STF8300c CCD camera on a Paramount ME taken in Mayhill, NM on the nights of 13, 14 Oct 2016; 16 Nov 2017; 13, 15 Dec 2017, and 13, 19 Jan 2018 (33 X 1200 sec lights @ -15 degrees C; 18 darks, 128 bias; 128 flats).
