M45_in_the_constellation_Taurus.jpg
Messier 45 in the constellation Taurus340 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 image was processed with multiscale processing in PixInsight. The image taken with 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; Sub-exposures calibrated, registered, integrated, and processed in PixInsight 1.8.2.1098.
Mercury_Transit_0818MT_SV80ED_CaK_41AU02.jpg
Mercury Transit 2016146 viewsThe Mercury transit was well underway when this image was taken at 8:17 AM MT on 5/9/2016 from the AAG outreach event at Imago Dei Academy in Alamogordo, NM. The image was taken using a Stellaruve 80ED refractor with a Lunt B1200 Calcium-K module and Imaging Source 41AU02 camera. The Calcium K-line (393.4 nm) shows supergranulation in the lower chromosphere (~1200 km) along with lighter regions indicating magnetic activity. Sunspot AR2542 along with the small disk of Mercury are also visible.

Reflection Nebula IC 2118454 viewsIC 2118 is a reflection nebula in the constellation Eridanus, which is believed to be an old supernova remnant that is illuminated by the nearby supergiant star Rigel in the constellation Orion. The image was taken with a Takahashi E-180 f/2.8 astrograph and a modified Canon 40D on a Paramount. Total exposure was 4 hrs 50 min; Calibrated in Images Plus 5.0; Gradient extraction; background neutralization, color balance in PixInsight 1.8; Adobe Photoshop CS6

M16324 viewsMessier 16 (M16) The Eagle Nebula is a conspicuous region of active star formation, situated in Serpens Cauda. The starforming nebula, a giant cloud of interstellar gas and dust, has already created a considerable cluster of young stars. The cluster is also referred to as NGC 6611, the nebula as IC 4703. The distance is 7000 light years.
The_Soap_Bubble_sRGB.jpg
The Soap Bubble in the Nebulosity of Cygnus114 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]).

The faint nebula was discovered relatively recently in 2008 on photographs of the Cygnus region. A cropped hydrogen-alpha image attached. Image was a total of 5 hr 40 min taken with a Takahashi CCA-250 f/5 astrograph with a QSI683wsg camera (Astrodon Gen2 Ha filter 5 nm) on a Paramount on the nights of 2, 4 October 2016 in Mayhill, NM (17 x 1200 sec H-alpha lights @ -20 degrees; 23 darks; 128 flats; 126 bias; processed in PixInsight 1.8.4.1195).

HaOIIIcombined1_Annotated_Medium.jpg
A portion of the Eastern Veil Nebula in Cygnus7 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).

NGC1342VdB18finalLJEPG.jpg
AN OPEN CLUSTER IN THE DUST CLOUDS OF PERSEUS34 viewsThe open cluster NGC 1342 is found in the constellation Perseus. The cluster is estimated to be 400 million years old and about 1,700 light years away. As seen in the image, dust clouds are prevalent in the area. To the upper left in the image is the blue reflection nebula VdB 18. The image is a total of 1 hour 45 min exposure taken with a Takahashi FSQ 106ED with focal reducer f/3.6 and a Canon 60Da (ISO 800) on an Astro-Physics 1200 Mount taken on 5 Dec 2016 in Mayhill, NM (7 x 900 sec lights, 18 darks, 128 bias, 128 flats). Process with PixInsight 1.8.5.Nov 01, 2017
NGC1579.jpg
The Northern Trifid in Pegasus25 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
M82IFN.jpg
A Starburst Galaxy and the Integrated Flux Nebula (IFN)23 viewsThis HaLRGB image portrays the turbulent starburst galaxy Messier 82 in Ursa Major with its filamentary outflows of ionized hydrogen. Seen faintly in the image is the IFN, which is illuminated by the combined flux of the stars in the Milky Way Galaxy. Total of 18 hrs exposure with a Takahashi CCA-250 f/5 astrograph; Nights of 15, 24, 28 March 2015; 12, 13 Jan 2016; 8, 9 Feb 2016 in Mayhill, NM: Paramount ME, QSI683wsg, Astrodon Gen2 filters (Ha 5 nm); (Lum 16 x 20 min; Ha 17 x 20 min; R 7 x 20 min; G 7 x 20 min; B 7 x 29 min all @ - 20 degrees C), calibrated, registered, integrated, and processed in PixInsight 1.8.5.1353 (x 64).

DoubleClusterFinalwPScc_sRGB.jpg
Double Cluster in the Perseus arm of the Milky Way57 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).

NGC6910_L.jpg
A Young Open Cluster in a Nebulous Complex 204 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
