The Crescent Nebula in Ha and O[III]120 viewsThe Crescent Nebula (NGC 6888) is an emission nebula found in the constellation Cygnus. The emission is powered by strong stellar winds from a Wolf-Rayet star colliding with previously expelled outer envelopes of the stars atmosphere. This image is a combination of 5 hrs of H alpha data (Astrodon 5 nm Gen 2 filter) and 5 hrs 20 m of O[III] data (Astrodon 3 nm Gen 2 filter). Taken with a Takahashi CCA-250 f/5 astrograph and QSI683wsg camera on a Paramount ME; August 11th , 13th and Sept 14th - 17th, 2015 in Mayhill, NM (Ha, 15 x 1200 sec lights @ -20o C; O[III], 16 x 1200 sec lights @ -20o C 21 darks; 126 bias; 128 flats) Image acquisition MaxIm DL 6.08; Processed in PixInsight Ripley (x64). The calibrated, aligned, and integrated Ha and O[III] images were stretched using Masked Stretch, Ha stretch matched to O[III] with Linear Fit, and combined using Pixel Math.Oct 23, 2015
Messier 27 in Vulpecula123 viewsMessier 27, which was discovered in 1764 by Charles Messier, is a bright planetary nebula in the constellation Vulpecula. The nebulosity is due to the expulsion of a star's outer layers in the later stages of its life and is illuminated by the stars intense radiation (blue star in the center of the nebula). Image was taken in Mayhill, NM on the nights of 14, 15, 16, 17 September 2015; total of 5 hrs 40 min exposure through an Astro-Physics 178 mm f/9 refractor with field flattener and an SBIG STF8300c camera with OAG (ST-i) on an Astro-Physics 1200 mount (17 x 20 min lights dithered @ -15o C; 33 darks; 128 bias; 128 flats); image acquisition with MaxIm DL 6.10 and processed with PixInsight Processing included Bayer drizzle, a Synthetic Luminance, and Multiscale Processing.

Lunar Eclipse of Sept 2015127 viewsThe 9/27/15 Lunar Eclipse in Mayhill, New Mexico (9/28/15 02:59:14 UT) taken with an Astro-Physics 178mm f/9 refractor with field flattener and SBIG STF8300c camera on an Astro-Physics 1200 mount; processed in PixInsight 28, 2015
M17 in narrowband (Hubble palette)158 viewsMessier 17 also known as the Swan Nebula or Omega nebula is located in the constellation of Sagittarius. The Nebula is composed mainly of ionized hydrogen. It is around 5,000 light years away from Earth and is one of the most massive star forming regions in the Milky Way galaxy. This false color image utilizes the Hubble palette that maps Ha to green, OIII to blue, and SII to red. Once the images from each filter are combined it creates an interesting photo. This was my first serious attempt at narrowband imaging and hopefully it will improve. The image consist of around 180 minutes of data from each filter.Sep 21, 2015
Cygnus Loop162 viewsThe Cygnus Loop, located in the constellation of Cygnus the Swan, is a supernova remnant that occurred after a massive star exploded between 5,000 to 10,000 years ago. The loop is about 3 degrees in size and continues to expand. The data for this image was obtained on the 17th and 19th of Jul 2015. It consist of 67 X 5min exposures obtained with a Canon 60Da camera, Orion ED80T telescope, and a Celestron CGEM mount.Sep 11, 2015
The Sadr Region in Cygnus192 viewsThe Sadr Region is a region around Gamma Cygni in the constellation of Cygnus the Swan. This area hangs high overhead in the northern hemisphere during the summer. Contained within this region is defuse nebula IC 1318, an emission nebula with several dark nebulas intermixed. Image was taken with a 100mm f7.2 refractor and Hap Griffin modified Canon 1000D with an Astrodon filter from Alamogordo, NM on 9/26/2014. Stack of 15 ea 4 min exposures processed using Nebulosity 2.5 and PS V7.01 using Carboni tools.Sep 07, 2015
The Crescent Nebula in Cygnus108 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 Ripley (x64).Sep 01, 2015
White Light Sun137 viewsSunspot AR2403 is almost 200,000 km long and is easily visible in this image taken from Maryland on 8/25/2015 using an Orion ED80T Triplet refractor and a color Atik 414ex camera. The telescope was equipped with a white light filter and the exposure was set to 0.001 sec. Light was further reduced by using a Moon filter in fromt of the camera. Great shot Chuck!Aug 25, 2015
The Soul Nebula 111 viewsThe emission nebula Sharpless 2-199 and the open cluster IC 1848 in the constellation Cassiopeia are commonly referred to as the soul nebula. The emission nebula is a massive star-forming region. The image was a total combined exposure of 8 hr 45 min taken over 6 nights (Aug and Oct 2014) in Mayhill, NM (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; guided with a ST-i camera and an Astro-Physics/Baader guider system; acquisition with MaxIm DL 6; Images calibrated, aligned, integrated, and processed in PixInsight 1.8.4 using a Synthetic Luminance and Multiscale Processing.

The Flaming Star Nebula 116 viewsThe Flaming Star Nebula, IC 405 or Caldwell 31, is found in the constellation Auriga. IC 405 is both an emission and reflection nebula that is associated with the star AE Aurigae. The image was taken using a Takahashi Epsilon 130D f/3.3 Astrograph and a SBIG STF8300c CCD camera (Paramount ME) on the nights of Nov 6th, 8th, 9th, 2013 in Mayhill, NM. Total integration time was 5 hrs 40 min (34 x 10 min lights at -20 degrees C; 20 darks; 64 lights; 64 bias). Sub-frames were calibrated, registered, integrated, and processed in PixInsight Ripley (x64). Aug 08, 2015
The Sun167 viewsThis image was taken from Alamogordo, NM on 8/8/2015 at 10:49AM MT using a Coronado 90mm SolarMax II telescope and Imaging Source 41AU02 monochrome camera. 688 images were stacked using Registax and a light LR deconvolution was performed before color added using Photoshop. Sunspot AR2396 is seen in the image and has grown by 50% in the last day.Aug 08, 2015
M 45 and associated Nebulosity228 viewsMessier 45, commonly known as the Pleiades, is an open cluster found in the constellation Taurus. Messier 45 is surrounded by a dusty reflection nebula, which accounts for its blue coloration, along with some pinkish-red coloration due to an ionized gas component. The small 17.3 magnitude galaxy PGC 13696 can be seen to the right of the star Electra (17 Tau), which is the bright star to the right of center.
The data was previously obtained on the nights of November 1st, 2nd, and 3rd, 2013 with a OSC SBIG STF-8300c camera and Takahashi E-130D f/3.3 Astrograph on a Paramount (Mayhill, NM). Total integration time was 4 hr 20 min (26 x 10 min lights @ -20 degrees C; 20 darks; 64 flats, 64 bias). Calibrated, registered, integrated, and processed in PixInsight
Some comments on processing: The calibrated, registered, and integrated OSC image was duplicated and the R, G, and B channels extracted. The R, G, and B channels were combined with the Integration Tool to prepare a synthetic luminance (SynL). Dynamic Background Extraction ( DBE) and Deconvolution applied to the SynL image. DBE, Background Neutralization, and Color Calibration was applied to the original RGB image. Both the RGB and SynL images were stretched (Masked Stretch tool). The luminance (“lightness” using L*a*b*) was extracted from the RGB image and the Linear Fit tool was used to match the stretch of the luminance to the SynL channel (SynL as reference). The fitted luminance was added back to the RGB image using the Channel Combination tool in L*a*b* mode. The SynLRGB image was made using LRGB Combine tool. Further processing included noise reduction, multiscale processing to bring out faint structure, color saturation, sharpening, and contrast enhancement.
