NGC_1499_California_Nebula.jpg
NGC 1499711 viewsNGC 1499, aka the California Nebula, is a diffuse nebula found in the constellation Perseus. The nebula, which is composed primarily of hydrogen gas, was discovered by E. E. Barnard in 1884 using a 6-inch refractor. The image is a total exposure of 3 hours 5 min (37 x 300 sec lights) using a Takahashi E-180 astrograph and a Canon 20Da DSLR at ISO 800 (30 darks, 67 flats). Image processed using Images Plus 3.82b and Adobe Photoshop CS5.

The Active Sun in Hydrogen Alpha635 viewsThis image was taken through a 40mm Coronado PST of the Sun on 12/27/2011 at 1925UT. The photograph is centered on the hydrogen alpha emission line at 656.28 nanometers (nm) and shows the chromosphere. Active Region 1384 is the dark region near the center of the photograph. A very large prominence is seen erupting along the rim of the Sun on the right.

The_reflection_Nebula_IC_2118_in_Eridanus.jpg
Reflection Nebula IC 2118580 viewsIC 2118 is a reflection nebula in the constellation Eridanus, which is believed to be an old supernova remnant that is illuminated by the nearby supergiant star Rigel in the constellation Orion. The image was taken with a Takahashi E-180 f/2.8 astrograph and a modified Canon 40D on a Paramount. Total exposure was 4 hrs 50 min; Calibrated in Images Plus 5.0; Gradient extraction; background neutralization, color balance in PixInsight 1.8; Adobe Photoshop CS6
Crab_Nebula.jpg
Crab Nebula (M1)312 viewsThe Crab Nebula (M1) is a supernova remnant in the constellation of Taurus. In 1731 John Bevis found that M1 corresponded with the bright supernova recorded by Chinese astronomers in 1054 AD as a star bright enough to be seen during the day. The image consists of 47 exposures taken with a Canon 60Da camera, a TPO RC telescope and a Celestron CGEM mount. Exposures were stacked with Nebulosity and processed with PixInsight 1.8.

An Open Cluster and Nebula in the constellation Auriga92 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 192 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).

The Planetary Nebula Messier 27 with O[III] Envelope 168 viewsThe planetary nebula Messier 27 is found in the constellation Vulpecula, which was discovered in 1764 by Charles Messier. The nebula is approximately 815 light-years away. The outer Oxygen envelope was captured using an O[III] filter. The image is a total of 12 hr exposure taken through three different telescopes: 12.5 inch f/9 RCOS astrograph with a SBIG STF8300c CCD camera (Paramount ME); Astro-Physics 178 f/9 with a SBIG STF8300c CCD camera (Astro-Physics 1200); and a Takahashi CCA-250 f/5 with an QSI683wsg CCD camera (Astrodon 3nm O[III] filter) on the nights of 14, 15, 16, 17 Sept 2015; 15 June 2016; 16, 17, 23 Oct 2017 in Mayhill, NM (13 x 1200 sec Lights at -20 deg C; 24 Darks, 128 Bias; 128 flats).

A section of the Eastern Veil Nebula in Cygnus169 viewsPictured is a portion of the Eastern Veil Nebula, NGC 6992, in Cygnus, which was discovered by William Herschel in 1784. The Veil Nebula is the result of a supernova explosion about 15,000 years ago and is approximately 2,500 light-years away. This bicolor narrowband image was taken through a Hydrogen-alpha filter and an Oxygen[III] filter, with the Red channel assigned to H-alpha, Green channel assigned to O[III], and the Blue channel assigned to 90% O[III]. The image was a total of 8 hrs 20 min exposure with a Takahashi CCA-250 f/5 astrograph and a QSIwsg CCD camera with Astrodon filters (H-alpha 5 nm; O[III] 3 nm) on a Paramount ME in Mayhill, NM on the nights of 17, 23, 24 October 2017 (O[III]: 16 x 1200 sec lights @ -20 degrees C; H-alpha 9 x 1200 sec lights @ -20 degrees C; 24 darks; 128 bias; 128 flats).
