M46M47NGC2423inPuppis.jpg
Open Clusters M 46, M47, and NGC 2423 in Puppis125 viewsThe open clusters Messier 46, Messier 47, and NGC 2423 are found in the constellation Puppis embedded in a rich field of Milky Way stars. The small planetary nebula NGC 2438 that appears to be in M 46 is actually not associated with the cluster. M 46 was discovered by Messier in 1771. Smyth describes it as a “A noble, but rather loose assemblage of stars” (Smyth and Chambers, A Cycle of Celestial Objects, 2nd Edition, 1881, Oxford) whereas Webb describes it as a “Beautiful circular cloud of small stars” (Webb, Celestial Objects for Common Telescopes, 4th Ed, 1881, Longmans, Green, and Co ). William Herschel observed the small planetary nebula NGC 2438 in 1786. M 47 was also discovered by Messier in 1771 but not intermediately attributed to Messier due to a mathematical mistake in his coordinates. The cluster was described by Smyth as “a very splendid field of of large and small stars” (under the entry 38 H VIII) and Webb as a “Grand broad group, visible to the naked eye”. This wide field picture was taken with a Takahashi FSQ106ED with focal reducer (f/3.6), Canon 60Da DSLR camera (2.32 arcsec/pixel), and an Astro-Physics 1200 mount on 15 March 2015 in Mayhill, NM.. Total exposure of 1 hour (4 x 15 min lights, dithered; 12 darks; 128 bias; 64 flats); Baader/Astro-Physics guider system; Image acquisition with MaxIm DL; Calibration, alignment, integration, and image processing with PixInsight 1.8.3.1123.Jun 21, 2015
NGC_6992_and_NGC_6995.jpg
NGC 6995 and NGC 6992 (The Eastern Veil Nebula)205 viewsNGC 6995 / NGC 6992 (Eastern Veil Nebula) form part of the Cygnus loop a supernova remnant in the constellation of Cygnus. Other objects that form part of the Cygnus loop, not visible in this image, are NGC 6960 and NGC 6979. The cloud of ionized gas and dust covers an area of 3 degrees (around 6 times the size of the full moon) and continues to expand. The image consist of 44 x 300sec exposures taken with a QHY10 CCD camera and Orion 80mm refractor mounted on a Celestron CGEM mount.Jun 15, 2015
Saturn_2015_05_31_C9_25_f30_21AU618.jpg
Saturn: The Bringer of Old Age227 viewsIn the ancient Roman myths Saturn was the god of agriculture, Greeks called Saturn Cronus - this is where we get the idea of Father Time. Saturn takes 29.5 years to orbit the Sun - thereby making it the slowest moving of the visible planets in the night sky. Saturn was 8.976 AU (~830 million miles) distant in this image. Image taken from Alamogordo NM with a Celestron C9.25 at f30 using an Imaging Source 21AU618 color camera and stacked with Registax 5.1 (3206 images) and L-R deconvolution using Astra Image 3.0 SI.May 31, 2015
Iris_Nebula.jpg
Iris Nebula (NGC 7023/C4)238 viewsNGC 7023 and Caldwell 4, aka the Iris Nebula, is a reflection nebula in the constellation of Cepheus. The dust in the nebula is illuminated by the magnitude +7 star SAO 19158. The image consist of 66 x 300sec images taken with a Explore Scientific 127mm refractor, Canon 60Da, and a Celestron CGEM mount. Stacked with Nebulosity 4 and processed in PhotoShop CS6May 27, 2015
Sh2-206_Supernova_Remnant_in_the_Constellation_Taurus.jpg
Sh2-240 Supernova Remnant in Taurus129 viewsImaged is the large supernova remnant Sharpless 2-240 in the constellation Taurus. The complex filamentary structure leads to it's common name, the Spaghetti Nebula. Field of view of the image is 2.12 x 3.21 degrees that captures only part of the nebula, which is approximately 3 degrees. Emission of the nebula is believed to be due to the shock wave of the expanding gas. Image was captured through a Takahashi FSQ 106ED with focal reducer (f/3.6 fl =385mm) and a Canon 60Da DSLR on an Astro-Physics 1200 mount; 23rd and 27th Oct 2014 (20 x 900 sec lights @-20 degrees, dithered; 35 darks; 126 flats; 128 bias; Software: SkyX, MaxIm DL 6, processed in PixInsight 1.8.3.1123).

Double_Cluster_in_Perseus.jpg
The Double Cluster in Perseus140 viewsThe Double Cluster in Perseus, NGC 869 and NGC 884, are bright (naked-eye visible as a hazy patch) relatively young open clusters. Each cluster contains about 300 stars, many of which are blue-white supergiants. Image is a total of 5 hours combined exposure (20 x 900 sec lights, -20 degrees C; 35 darks; 126 flats; 128 bias) taken with an SBIG STF8300c camera; Takahashi Epsilon 180 f/2.8 astrograph; Astro-Physics 1200 mount; Image acquisition with MaxIm DL 6; processed with PixInsight 1.8.3.1123.

M78_contrast_Labels_noCircles.jpg
Messier 78 and neighbors242 viewsMessier 78 is a diffuse reflection nebula located in the constellation of Orion. The starlight bounces off the dust particles in the nebula which create the bright reflection areas. The dark area that separates M78 from NGC 2067 consist of obscuring dust that blocks the light from background stars. The image consist of over 10 hours of data (128 x 5min exposures) taken with a Canon 60Da camera, TPO RC telescope on a Celestron CGEM mount. Stacked with nebulosity and processed with Photo Shop CS6. Apr 01, 2015

IC_443_in_Gemini.jpg
The Jellyfish Nebula in Gemini162 viewsThe Jellyfish Nebula, also designated IC443, is a large supernova remnant in the constellation Gemini. The supernova explosion is suggested to have occurred approximately 30,000 years ago. The emission of the nebula is due to the excitation of hydrogen atoms as the expanding shell collides with the surrounding molecular gas (shock wave). The image was taken with a TeleVue 140 f/5 refractor and a SBIG STF8300c camera (OAG with ST-i) on an Astro-Physics 1200 mount. Total combined exposure of 3 hr 20 min (10 x 1200 sec lights @-20 degrees C, dithered; 21 darks, 128 bias, 128 flats). Acquisition MaxIm DL 6; Images calibrated, registered, integrated, and processed in PixInsight 1.8.3 with final adjustments with Adobe Photoshop CC. Mar 28, 2015

IC 1848 and associated Nebulae in the Perseus Arm of our Milky Way149 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.Mar 19, 2015

Orion_Final.jpg
Orion Nebula (M42)237 viewsThe Orion Nebula (M42) is a diffuse nebula located in constellation of Orion. It is one of the most popular objects in the night sky and is visible with the naked eye from a dark location. Near the center you will find the Trapezium (the small group of four stars) containing some of the youngest stars in the Milky Way. Can you find the wolf face near the Trapezium? This image consist of 20 x 30 sec, 10 x 60sec, 5 x 180sec, and 5 x 300 sec images taken with a QHY-10 CCD camera, TPO RC telescope, and Celestron CGEM mount.
