M571046 viewsMessier 57 the Ring Nebula appears in the northern constellation of Lyra is a prominent example of a planetary nebula. This is a shell of ionized gas expelled into the surrounding interstellar medium by a red giant star, which was passing through the last stage in its evolution before becoming a white dwarf. The distance is 2300 light years.

The Planetary Nebula Messier 27 with O[III] Envelope 572 viewsThe planetary nebula Messier 27 is found in the constellation Vulpecula, which was discovered in 1764 by Charles Messier. The nebula is approximately 815 light-years away. The outer Oxygen envelope was captured using an O[III] filter. The image is a total of 12 hr exposure taken through three different telescopes: 12.5 inch f/9 RCOS astrograph with a SBIG STF8300c CCD camera (Paramount ME); Astro-Physics 178 f/9 with a SBIG STF8300c CCD camera (Astro-Physics 1200); and a Takahashi CCA-250 f/5 with an QSI683wsg CCD camera (Astrodon 3nm O[III] filter) on the nights of 14, 15, 16, 17 Sept 2015; 15 June 2016; 16, 17, 23 Oct 2017 in Mayhill, NM (13 x 1200 sec Lights at -20 deg C; 24 Darks, 128 Bias; 128 flats). Calibrated, Registered, Integrated, and Processed in PixInsight 1.8.5.1353 Ripley (x64).

Antares, M4 and the Rho Oph cloud1230 viewsAntares is the bright star at the lower left of the image. It is over 700 times the diameter of our Sun. Globular cluster Messier 4 is seen on the lower right. The Rho Ophiuchus cloud complex is the closest star forming region to our solar system (~430 lght years away). The cloud complex is much larger than can fit in this image. Blue reflection nebula IC 4605 seen about mid-left, and IC4603 seen middle-top are created by interstellar dust.

Heart Nebula (IC 1805)847 viewsThe Heart nebula (IC1805), an emission nebula is located in the Perseus arm of our galaxy. The nebula spans around 4 times the diameter of the full moon. It is estimated to be 7,500 light-years away from our planet. This photo consist of 3 hours of exposure (3 and 5 min exposures) taken with a Canon 60Da thru an Orion 80mm telescope on a Celestron CG-5.

M17_Hubble_post.jpg
M17 in narrowband (Hubble palette)685 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.

The Great Globular Cluster in Hercules778 viewsMessier 13, or the Great Globular Cluster in Hercules, was discovered by Edmond Halley in 1714. The cluster is estimated to contain from 300,000 to a half-million stars and is about 26,000 lights years distant from our solar system. The image was taken with a 12.5” RCOS f/9 telescope operating at f/5.94 (Astro-Physics CCDT67 telecompressor) and a SBIG STF8300c camera on a Paramount ME in Mayhill, NM on 28 May 2016 (6 x 20 min lights @ -20 degrees C; 40 darks; 128 bias; 128 flats). Processed with PixInsight 1.8.4.1195.

NGC_4631_RCOSf6_DarkMottleRepFinal_Large.jpg
The Whale Galaxy in Canes Venatici414 viewsNGC 4631 is found in the constellation Canes Venatici. The wedge-shape of this galaxy gives rise to its nickname, the Whale Galaxy. The starburst regions of this galaxy can be seen in the photo, which are due to intensive star formation. Tidal interactions of NGC 4627, which is seen just above NGC 4631, has been suggested as one of the reasons for the active core of NGC 4631 (as well as tidal interactions with other nearby galaxies). The small edge-on galaxy at the top of the image is PGC 3794315 (NASA Extragalactic Database). Total of 5 hr 40 min exposure taken with an SBIG STF8300c CCD camera and a 12.5 inch RCOS f/9 astrograph operating at f/6 (Astro-Physics CCDT067 reducer) mounted on a Paramount ME on the nights of 8, 15, 16 May 2018 in Mayhill, New Mexico (17 x 1200 sec Lights @ -15 degrees C; 15 darks; 128 bias; 128 flats).

IC_443_Large.jpg
Turbulent nature of the Jellyfish Nebula565 viewsFound in the constellation Gemini, the Jellyfish Nebula, also designated IC 443, is a large supernova remnant. The emission of the nebula is due to the excitation of hydrogen atoms as the rapidly expanding shell collides with the surrounding molecular gas. This hydrogen-alpha image shows the turbulent nature of the nebula as the resultant shock wave expands. Image taken with a Takahashi CCA-250 f/5 astrograph and QSI683wsg CCD camera (Astrodon 5nm H-alpha filter) on a Paramount ME in Mayhill, NM on the nights of the 23rd, 24th January 2018. Total of 7 hr exposure (21 x 1200 sec lights @ -20 degrees C; 24 darks; 128 bias; 128 flats). Processed in PixInsight 1.8.5.1353 Ripley (x 64).Jun 30, 2018
