  • The cover story of the July edition of Sky and Telescope is about the finding of the Soap Bubble nebula by an amateur astronomer. Page 34 of the magazine had a picture which was almost the same field of view to one I took last September. Above is my September shot and buried in the bottom left quadrant is this elusive object...boy is it faint. NP101is telescope and ML8300 camera. Exposure 14x15m in Ha.

In extreme cases, we might expect to see multiple images of the same object, formed by light that has gone around opposite sides of the intervening mass. The first examples of such lensing involved quasars, as the brightest objects seen at large distances. This quasar was the first confirmed lensing case, the double quasar 0957+561. It was found while searching for counterparts of radio sources, when two candidates showed up only 6 arcseconds apart (altered text from Wikipedia). <br /> The picture was taken at Grafton, Ontario with C9.25 and ML8300 camera, by Lynn Hilborn, May 2010

  • 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)
