NIGHT OVER ONTARIO

These photos were taken by Lynn Hilborn of Grafton, Ontario.
Pictures have appeared on the cover and inside editions of SkyNews magazine and in Sky & Telescope and Astronomy magazine, and as NASA's Astronomy Picture of the Day.

“ 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,”
W.B.Yeats

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 />

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)
