Jupiter_6_21_09.jpg
Jumpin' Jupiter!867 viewsJupiter is nearing its 2009 opposition - so I thought I'd go out and practice. Shot with the Celestron C9.25/CGE at f/25 (5875mm) with the NexImage/Televue Powermate (2.5x) from the backyard. I shot at 20 fps to get the most amount of images (1800). Stacked with Registax 2.0, Processed with Photoshop 7.0.1.

Orion Nebula563 viewsWide-field photo of the Orion Nebula (M42 and M43) along with the Running Man (NGC-1977) taken with a Takahashi E-180 astrograph and a Canon 20Da DSLR camera. The total exposure was 25 minutes (5 X 300 seconds); calibrated, aligned, and stacked in Images Plus and processed in Photoshop CS4.
IC_405.jpg
The Flaming Star Nebula545 viewsThe Flaming Star Nebula, designated IC 405 or Caldwell 31, is found in the constellation Auriga. IC 405 is both an emission and reflection nebula and is associated with the star AE Aurigae. The image was captured using a Takahashi E-130D f/3.3 astrograph and a SBIG STF-8300c CCD camera on a Paramount.

The_Bubble_SH2_162_NGC_7635_in_Cassiopeia.jpg
The Bubble Nebula in Cassiopeia686 viewsThe bubble nebula, NGC 7635, is a large emission nebula in Cassiopeia. The “bubble” is the result of a stellar wind from a massive young star, which is thought to be 10 to 40 times the mass of our sun. The image exposure time was a total of 12 hours 5 minutes (145 x 5 minutes lights; 33 darks; and 64 flats) with an Astro-Physics 130 mm f/8 refractor and SBIG ST2000xcm ccd camera on an Astro-Physcs 1200 mount.

A Large Emission Nebula in Cassiopeia1 viewsNGC 281 is a H II emission nebula in Cassiopeia containing the open cluster IC 1590, which powers the ionization of the hydrogen gas. Large dust filaments as well as Bok globules, which may be the site of future star formation, can be seen. The image is a total of 5 hrs 20 min exposure in H alpha light. Image taken with a Takahashi CCA250 astrograph and QSI683wsg camera on a Paramount ME on the nights of 13, 15 Dec, 16 Nov 2018 in Mayhill, NM (16 x 1200 sec lights @ -20 degrees C.

NGC4565Large.jpg
An Edge-On Spiral Galaxy in Coma Berenices7 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. Total exposure was 10 hrs 20 min taken with a Takahashi CCA-250 f/5 astrograph and QSI683wsg CCD camera (Astrodon Gen2 filters) on a Paramount ME in Mayhill, NM on the nights of 8, 15, 16 May; 17, 18 June 2018 ( 21 x 1200 sec lights; 4 x 1200 sec R; 3 x 1200 sec G; 3 x 1200 sec B all @ -20 degrees C; 24 darks; 128 bias; 128 flats for each channel).

NGC_4631_RCOSf6_DarkMottleRepFinal_Large.jpg
The Whale Galaxy in Canes Venatici41 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 Nebula49 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

An Open Cluster and Nebula in the constellation Auriga311 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 296 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).
