Messier_45_with_Epsilon_130.jpg
The Pleiades Open Star Cluster414 viewsMessier 45, commonly known as the Pleiades or Seven Sisters, is found in the constellation Taurus. The structure in the nebulous regions is created by interstellar magnetic fields. The image was captured using a Takahashi E-130D f/3.3 astrograph and a SBIG STF-8300c camera on a Paramount. Total integration time was 4 hr 20 min (26 x 10 min lights @ -20 degrees C; 20 darks; 64 flats, 64 bias). Images were graded in Images Plus 5.0; Subs calibrated, registered, integrated, and processed in PixInsight 1.8 Ripley with final levels/curves adjustment in Adobe Photoshop CC.
NGC_2264.jpg
NGC 2264331 viewsNGC 2264, consist of two deep sky objects, the Cone Nebula and the Christmas Tree Cluster. Both located in the constellation of Monoceros. The star cluster is call the Christmas Tree while the Cone Nebula gets its name from the cone shape visible in photos. The cone nebula is a dark absorption nebula consisting of cold molecular hydrogen and dust in front of an emission nebula. The photo consist of 3.5 hours of exposure using Canon 60Da, Celestron C8, and a CGEM mount. Taken Christmas day 2013.
Lagoon_Nebula_Post.jpg
Lagoon Nebula (M8)418 viewsMessier 8 (Lagoon Nebul) a large emission nebula with a radius of 55 by 20 light years is located in the constellation of Sagittarius. This photo, taken the morning of 14 Jul 2013, is composed of 19 one minute exposures (still having problems) taken with an 8" f5 reflector and a Canon 60Da camera on a CG-5 mount.

Friday Night at the Orion604 viewsHere's another shot of the Orion nebula using the 6" SCT at f6.3 with an unmodded Canon Rebel XSi (15min total) done on 3/5/10. The nebula is seen as the middle "star" in the sword of Orion. The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features. It is located at a distance of 1,344 ± 20 light years. This is an example of a stellar nursery where over 700 new stars are being formed. Cool stuff!
The_Zeta-Orionis_Region.jpg
The Zeta Orionis Region805 viewsImage of the Zeta Orionis Region in the constellation Orion, which contains both the horsehead and flame nebula. This is a visible light image taken with a modified Canon 40D and a Takahashi Epsilon 180 f/2.8 astrograph (3hr 15 min total exposure). It is interesting to compare it to Jim's Narrowband Image (6th previous image) of the area which essentially maps the concentration of Hydrogen, Oxygen, and Sulfur.

Jupiter246 viewsOn 1/23/2015 the shadows of Io, Callisto, and Europa were visible from Earth as they transit across Jupiter. This photo shows Io's shadow (someone correct me if I am wrong) as it transited across the gas giant. The image consist of 2,000 video frames taken with an Imaging Source camera and a Meade 8" SCT mounted on a Celestron CGEM mount. Frames were stacked with Registax6 and processed with PhotoShop CS6 and Steve's touch.
ASIC410.jpg
IC 410 and the Tadpoles in Ha158 viewsThe emission nebula IC 410 and the embedded open star cluster NGC 1893 are found in the constellation Auriga. The emission of IC 410, which is about 12,000 light-years away, is powered by the young hot stars in NGC 1893. The gas streamers just to the right and above center, often called the “Tadpoles”, are moving away from the center of the nebula. The image is a Ha image, which shows the extent of the hydrogen emission in the region. The image was taken with a Takahashi CCA-250 astrograph and the QSI683wsg camera (SBIG ST-i guider) on a Paramount ME. The image is a total of 8 hours exposure (24 x 20 min lights @ -20 degrees C, dithered; 21 darks; 126 bias; 128 flats), acquired with MaxIm DL 6.07, and processed with PixInsight 1.8.3.1123 Ripley (x64). Ha filter was an 5nm bandwidth 31 mm Astrodon Gen 2 filter.
Messier_13_in_Hercules.jpg
The Great Globular Cluster in Hercules198 viewsMessier 13, or the Great Globular Cluster in Hercules, was discovered by Edmond Halley in 1714. The cluster is estimated to contain from 300,000 to a half-million stars and is about 26,000 lights years distant from our solar system. The image was taken with a 12.5” RCOS f/9 telescope operating at f/5.94 (Astro-Physics CCDT67 telecompressor) and a SBIG STF8300c camera on a Paramount ME in Mayhill, NM on 28 May 2016 (6 x 20 min lights @ -20 degrees C; 40 darks; 128 bias; 128 flats). Processed with PixInsight 1.8.4.1195.

NGC1579.jpg
The Northern Trifid in Pegasus9 viewsThe Northern Trifid (aka NGC 1579) is found in the constellation Pegasus. Unlike its southern neighbor Messier 20 from which it got its name, the reddish hues are not a HII region but rather dust lighted by the reflection of a star with an unusual amount of H-alpha emission as well as interstellar extinction (S. J. O'Meara, The Secret Deep, 2011, pp 79-81). Our current understanding suggests the Northern Trifid is a vast dusty star-forming region. Image was taken with a SBIG 8300c CCD camera and a RCOS 12.5 inch f9 astrograph on a Paramount ME. Total combined exposure of 8 hr 20 min on the nights of 23 Nov, 30 Nov, 5 Dec 2016 in Mayhill, NM (25 x 1200 sec lights @-15 degrees C; 18 darks, 128 bias; 128 flats); Processed in PixInsight 1.8.5.1353 (64 bit).Oct 15, 2017

DoubleClusterFinalwPScc_sRGB.jpg
Double Cluster in the Perseus arm of the Milky Way36 viewsThe Double Cluster in Perseus, aka NGC 884 and NGC 869, lies in a rich star field of the Milky Way. A favorite object at public star parties, most observers can pick out an orange star among the bright blue stars of the clusters. Studies suggest that the Double Cluster is relatively young and is approximately 7,500 light-years away. Image is a total of 2 hours exposure taken with a Canon 60Da and a Takahashi FSQ106ED with focal reducer (f3.6) on an Astro-Physics 1200 mount taken in Mayhill, NM on the nights of 23, 30 Nov 2016 (8 x 900 sec lights; 18 darks, 128 bias, 128 flats). Processed with PixInsight 1.8.1195 with final adjustments in Photoshop CC.Jul 09, 2017
The_Soap_Bubble_sRGB.jpg
The Soap Bubble in the Nebulosity of Cygnus93 viewsThe Soap Bubble Nebula, or PN G755.5+1.7, is found in the constellation Cygnus. The Soap Bubble is likely a symmetric planetary nebula, which is the expanding shell of ionized gas ejected from a star late in its lifetime. The faint nebula was discovered relatively recently in 2008 on photographs of the Cygnus region. Image was a total of 17 hr 20 min exposure taken with a Takahashi CCA-250 f/5 astrograph with a QSI683wsg camera (Astrodon Gen2 H-alpha filter 5 nm; O[III] 3 nm) on a Paramount ME on the nights of 2, 4, 5, 21, 25, 26, 29, 30 October 2016 in Mayhill, NM (26 x 1200 sec H-alpha lights @ -20 degrees; 26 x 1200 sec O[III] lights @ -20 degrees; 23 darks; 128 flats of each filter; 126 bias; processed in PixInsight 1.8.4.1195; color assigned in SHO-AIP Red = 90 % H-alpha; G = 10% H-alpha and 100% O[III]; Blue = 100% O[III]).Apr 25, 2017
NGC6910_L.jpg
A Young Open Cluster in a Nebulous Complex 184 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) Mar 03, 2017
