IC_1275_2012_05_20_71FL_XS_120min_iso800_-_Cropped.jpg
IC 1275 region739 viewsIC (Index Catalog) 1275 is an emission nebula located within a rich star field in the constellation Sagittarius. The red color is due to ionized hydrogen gas (HII regions) being excited by nearby stars. Image taken through a Borg 71FL and modified Canon XS DSLR (two hour exposure, stacked with Nebulosity and processed in Photoshop).
NGC_6559___IC_1275_region.jpg
NGC 6559, IC 1274/75, and IC 4685 region in Ha639 viewsThe IC 1274/75, IC 4685 and NGC 6559 complex imaged in Ha are located in the constellation Sagittarius (visible light photo previously posted). Just to the right of NGC 6559 (the brightest emission nebulosity slightly below left of center in the image) in the large HII region IC 4685 is the serpentine structure of the dark nebula Barnard 303. Total exposure 1 ½ hours (TeleVue 85 refractor; SBIG ST 2000 ccd camera @ -13 degrees; Paramount; Baader 35 nm bandwidth Ha filter; 30 x 5 min lights; 35 darks; 41 flats).

Messier 27 through Ha, OIII, and SII filters499 viewsMessier 27 is a nebula found in the constellation Vulpecula, often shown in the summer and early fall at our Oliver Lee star parties. This image is through narrowband filters, where Hydrogen alpha is mapped to green (2 hr 25 min combined exposure); Oxygen, OIII, is mapped to blue (3 hr 15 min combined exposure), and Sulfur, SII, is mapped to red (5 hr 40 min combined exposure); taken with a Takahashi FSQ106ED and SBIG ST2000xm camera with Baader filters.
Open_Cluster_IC_1848_and_SH2_199.jpg
IC 1848 and associated Nebulae in the Perseus Arm of our Milky Way119 viewsIn the center of the image is the open cluster IC 1848, which is in the constellation Cassiopeia. The open cluster is surrounded by the emission nebula SH2-199, which is a massive star forming region. The small emission nebula IC 1871 is seen partially at the top center. The entire nebulous region is often called the Soul Nebula. Image was a total combined exposure of 8 hr 45 min taken over 6 nights (35 x 900 sec lights at -20 degrees, dithered; 35 darks, 128 bias, 128 flats); Takahashi Epsilon 180 f/2.8 astrograph; Paramount ME; SBIG STF 8300c; ST-i guide camera using Astro-Physics/Baader guide system; Maxim DL 6; PixInsight 1.8.3; Adobe Photoshop CC.
The_Flaming_Star_Nebula.jpg
The Flaming Star Nebula643 viewsThe Flaming Star Nebula, IC 405, is located in the Constellation Auriga. The nebula is illuminated by the variable star AE Aurigae that is slowly passing thru the nebula but in fact did not condense from the surrounding nebula. The image acquired with a Canon 20Da DSLR (ISO 800) and a Takahashi E 180 astrograph. Total exposure time of 2.5 hrs (30 X 300 seconds lights calibrated, aligned, stacked, and stretched (DDP) in Images Plus 3.80 and further processed in Adobe Photoshop CS4).
Catalina_Final.jpg
Comet Catalina109 viewsComet Catalina as of the morning of December 17, 2015. Image taken with an ES127mm refractor and a Canon 60Da camera.
M33-Dark-color-small.jpg
St2000XCM-M33 10-13-07503 viewsThis is a single 10 minute image. It shows better detail than the last one, just not enough signal.
Jupiter_6_21_09.jpg
Jumpin' Jupiter!632 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.

The_Soap_Bubble_sRGB.jpg
The Soap Bubble in the Nebulosity of Cygnus53 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 140 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
NGC1491.jpg
NGC 1491144 viewsNGC 1491 is an emission nebula found in the constellation of Perseus. It is located over 10,000 light-years from Earth and it forms part of the larger Sharpless 206 nebula. This image consists of over 5 hours of imaging with a Canon 60Da camera, 8” TPO telescope on a Celestron CGE Pro mount. Calibrated, stacked, and processed with PixInsight 1.8Feb 11, 2017
Running_man_ABE_ps.jpg
NGC1973150 viewsNGC 1973 (Running Man Nebula) is a reflection nebula associated with Orion’s molecular cloud. The nebula is located just .5 degree north of the Great Orion Nebula and 1,500 light years away from Earth. The blue color derives from the interstellar dust reflecting the light from the surrounding young stars. The image consists of 75 x 5min exposures taken with a Canon 60Da and TPO 8” RC telescope mounted on a Celestron CGE Pro mount. Images were stacked with Nebulosity 4 and processed with PixInsight 1.8 Jan 04, 2017

M1finalJPEG.jpg
The Crab Nebula in Oxygen[III] and Hydrogen-alpha Emission 184 viewsMessier 1, the Crab Nebula, is a supernova remnant found in the constellation Taurus. M1 was discovered by John Bevis in 1731 (independently discovered by Charles Messier in 1758). Admiral Smyth describes M1 as a “large nebula, pearly white” and of “oval form” in his Cycle of Celestial Objects (2nd edition, page 145). This bi-color image is a total of 17 hrs 20 min exposure using a Takahashi CCA-250 f/5 astrograph and a QSI683wsg CCD camera (Astrodon Gen 2 filters; H-alpha 5 nm; O[III] 3 nm) on a Paramount ME (26 x 1200 sec O[III] lights, 26 x 1200 sec H-alpha lights; 21 darks, 126 bias, and corresponding flats and flat darks). Color assignment H-alpha = red; 15:83 H-alpha:O[III] = green; O[III] = blue; processed in PixInsight 1.8.4.1195.Nov 27, 2016
