“ Had I the heavens' embroidered cloths,
Enwrought with golden and silver light,
The blue and the dim and the dark cloths
Of night and light and the half light,”

  • Simeis 147 (SH2-240) Natural colour representation. Supernova remnant taken by Lynn Hilborn, WhistleStop Observatory, Grafton, Ontario. Lens- Tokina f2.8 300mm, camera- FLI ML8300 using Baader narrowband filters. Ha 11x30minutes 1x1, OIII 11x30minutes 3x3, SII 6x30minutes 2x2. Total 14 hours exposure. Image taken Nov 21, 23, 30 and Dec 02, 2011.<br /> <br /> It's easy to get lost following the intricate filaments in this image of faint supernova remnant Simeis 147. Also cataloged as Sh2-240 and seen towards the constellation Taurus, it covers nearly 3 degrees (6 full moons) on the sky. That corresponds to a width of 150 light-years at the stellar debris cloud's estimated distance of 3,000 light-years. The composite includes image data taken through narrow-band filters to highlight emission from hydrogen and oxygen atoms tracing regions of shocked, glowing gas. This supernova remnant has an estimated age of about 40,000 years - meaning light from the massive stellar explosion first reached Earth 40,000 years ago. But this expanding remnant is not the only aftermath. The cosmic catastrophe also left behind a spinning neutron star or pulsar, all that remains of the original star's core. (Text from APOD)

Taken with TEC 140 @f5.6 and FLI ML8300 camera at -30C.<br /> Shot July 05,09,10, 2012 by Lynn Hilborn, WhistleStop Obs,Grafton, Ontario.<br /> M20 (Trifid Nebula) (Barnard 85) (NGC 6514)<br /> <br /> Distance: 5500 to 9000 light years<br /> <br /> Right Ascension: 18 : 02.3 (hours : minutes)<br /> Declination: -23 : 02 (degrees : minutes)<br /> <br /> Text Copyright Robert Gendler 2006<br /> A gem of the summer sky, M20 allows us a view into the exciting science of star birth. M20 is a young HII region (300,000 years old) about 30 light years across and is illuminated by the O-type supergiant HD 164492 at the center of its trilobed emission cloud. The ionizing star is about 30 times the mass of our sun and is the "A" component of a triple system ( A, B, and C components). In all there are seven members (HD 164492 A through G) of the small cluster packed within a half light year at the center of M20. As an HII region M20 is similar to M42 in its complexity and relationship to its parent molecular cloud but is much younger. A large blue reflection cloud forms the northern border of M20 and is illuminated solely by the F-type supergiant HD 164514. Recent X-ray and infrared observations have discovered an amazing array of very early stars and protostars within M20 giving us a rare glimpse of the earliest stages of star birth.<br /> <br /> Stars in the earliest formative stages are difficult to detect optically as they are shrouded from view by their parent molecular cloud. They reveal their presence by jets and outflows of gas which characterize their unstable and turbulent beginnings. The power of infrared observations (Spitzer Observatory) allows astronomers to "see" beyond the cloak of gas and dust that obscures young stars. Large populations of the earliest protostars or pre- main sequence stars (Class O and I) have been detected along the filamentary dark lanes near the reflection component. More evolved protostars (Class II) are found along ionization fronts within the rounded brighter parts of the emission cloud. Text with thanks to Robert Gendler.

  • What was the first telescope image for the masses ? (no pun intended) <br /> In the Basilica of Santa Maria Maggiore, in Rome, there is a fresco of the Virgin Mary standing on a pock-marked moon as seen through Galileo's telescope and painted by Lodovico Cigoli in 1611.<br /> Cigoli. a friend of Galileo, was the first to paint a telescope-sighted moon in the visual arts....the first telescope-imaged APOD ( Astronomy Painting Of the Day).<br /> Photo by Lynn Hilborn, September 30, 2012
  • Identication of LDN 988 and environs. V1331 Cyg, a T Tauri star located in LDN 984. V1331 Cyg is known as a FU Orionis pre-outburst candidate. This star is embedded in a circumstellar bright nebulosity and is also surrounded by helix-shaped nebula originated from the star. Thanks to Bernhard Hubl for this information.<br /> 11 hour exposure taken with TEC 140 @f5.6 and FLI ML8300 camera.<br /> RGB each 2 hours (12x10m bin 1x1), Lum 5 hours (30x10m bin 1x1).<br /> Taken by Lynn Hilborn, WhistleStop Obs, Grafton, Ontario on August 24,25 and September 6, 2012
  • Pelican's Neck Ha 4x30m bin 1x1 TEC 140 @f5.6 and ML8300. Taken by Lynn Hilborn August 3, 2012.<br /> The prominent ridge of emission featured in this skyscape is designated IC 5067. Part of a larger emission nebula with a distinctive shape, popularly called The Pelican Nebula, the ridge spans about 10 light-years and follows the curve of the cosmic pelican's head and neck. Fantastic, dark shapes inhabiting the view are clouds of cool gas and dust sculpted by energetic radiation from hot, massive stars. But stars are also forming within the dark shapes. In fact, twin jets emerging from the tip of the central, dark tendril are the telltale signs of an embedded protostar cataloged as Herbig-Haro 555. The Pelican Nebula itself, also known as IC 5070, is about 2,000 light-years away. To find it, look northeast of bright star Deneb in the high flying constellation Cygnus.
