CrescentNebula.jpg
The Crescent Nebula in Cygnus73 viewsThe Crescent Nebula (NGC 6888) is an emission nebula found in the constellation Cygnus. A leading hypothesis suggests that the strong stellar winds from the central Wolf-Rayet star collides with the stars outer atmospheric envelope ejected in a previous evolutionary phase, which energizes the nebula and leads to the observed structure. This H alpha image is a total of 5 hours of exposure taken with a Takahashi CCA-250 f/5 astrograph and QSI683wsg camera (Astrodon 5 nm Ha filter) on a Paramount ME; August 11th , 13th 2015 in Mayhill, NM (15 x 1200 sec lights @ -20o C; 21 darks; 126 bias; 128 flats) Image acquisition MaxIm DL 6.08; Calibration, alignment, integration, and processing in PixInsight 1.8.4.1107 Ripley (x64).
NGC6910_L.jpg
A Young Open Cluster in a Nebulous Complex 114 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)
Jelly_FishNebula.jpg
IC443 (Jellyfish Nebula)212 viewsIC443 (Jellyfish Nebula) is the supernova remnant of a massive star that exploded thousands of years ago. The nebula is located around 5,000 light years away from Earth in the constellation of Gemini. This image consist of 80 x 5min exposures taken with a Canon 60Da camera, Orion ED80T refractor, and a Celestron CGEM mount.
Crab_Nebula.jpg
Crab Nebula (M1)109 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.
Vega_Betelgeuse_spectra.jpg
A Tale of Two Stars688 viewsHere are basic spectra from two familiar stars in the night sky. Vega's spectra is on the left and basically has weak spectral lines based mostly on the Hydrogen Balmer series. This is indicative of a fairly young, hot star. Betelgeuse's spectra is far more complex. We can see spectral lines for Barium, Calcium, Iron and Magnesium and compounds like Vandium Oxide and Titanium Oxide indicative of a star near the end of its life. Data collected with amateur equipment and processed through RSpec software.
NGC_6559_post~0.jpg
NGC 6559 wide field of view237 viewsThis image shows a wider view of my previously posted NGC 6559. This image is a combination of 50 X 300sec exposures with a Canon 60Da connected to an Orion 80mm refractor mounted on a Celestron CGEM. Stacked with Nebulosity 3.0 and processed with PhotoShop CS6
2011_10_03_Whitelight_CaK_composite.jpg
What a diiference a filter makes!641 viewsHere is the Sun taken on 10/3/11 at 11:15 AM first in White light (left) and Calcium K (right) using a Stellarvue 80ED. The white light image shows a few sunspot groups while the CaK image shows much more detail and areas of increased magnetic activity. AR1302 is on the far right, nearly rotating out of view. The white light image was taken using an Orion glass filter and single snapshot from a Canon T2i. The CaK image was taken with an Imaging Source camera and Lunt B1200 CaK filter.

The_Soap_Bubble_sRGB.jpg
The Soap Bubble in the Nebulosity of Cygnus21 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

M1finalJPEG.jpg
The Crab Nebula in Oxygen[III] and Hydrogen-alpha Emission 159 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
