A portion of the Eastern Veil Nebula in Cygnus733 viewsPictured is a portion of the Eastern Veil Nebula, NGC 6992, in Cygnus. The Veil Nebula is the result of a supernova explosion about 15,000 years ago. 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 70% H-alpha + 30% 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). Processed in PixInsight 1.8.5.1353 Ripley (x64).

A GLOBULAR CLUSTER IN LYRA981 viewsThe globular cluster Messier 56 is found in the part of Milky Way that runs through the constellation Lyra. Admiral Smyth describes M 56 as “a globular cluster in a splendid field” in his “A Cycle of Celestial Objects” (2nd Ed, 1881). The image was taken on 15 June 2016 in Mayhill, NM with a 12.5” RCOS f/9 telescope operating at f/5.95 (Astro-Physics CCDT67 reducer) and a SBIG STF8300c camera mounted on a Paramount ME. Exposure was a total of 1 hr 40 min (5 x 20 min lights @ -15 degrees C; 40 darks; 128 flats; 128 bias). Calibrated, registered, integrated, and processed in PixInsight 1.8.4.1195 Ripley (x64).
Running_man_ABE_ps.jpg
NGC1973793 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

M 45 and associated Nebulosity1142 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 1.8.3.1123.
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.
Ha_image_of_Messier_8_in_false_color.jpg
Hydrogen alpha image of Messier 81651 viewsM8, an emission nebula, is found in the constellation Sagittarius. A significant portion of it's composition is hydrogen, which emitts light due to the excitation of the hydrogen atoms from radiation coming from the embedded stars in the nebula. A particular wavelenght of this emission, Ha, was imaged using a narrowband filter and assigned a red color (TeleVue 85 refractor; 0.8 reducer/fattener; SBIG ST-2000 CCD; 25 x 5 min lights; 30 darks; 41 flats).

“37” Open Cluster in Orion23 viewsThe open cluster 2169, often called the 37 cluster or Shopping Cart cluster, is found in the constellation Orion. It was arguably discovered by Giovanni Batista Hodierna before 1694 and was independently discovered by William Herschel in 1784.
