Simeis 147 |
Simeis 147 (S-147) is a supernova remnant on the Taurus/Auriga border spanning a huge area, but is an extremely dim object. It is what is left of a supernova which exploded about 40,000 years ago and is estimated to be 3000 light-years away. It is best photographed with a Hydrogen-alpha filter and monochrome astrocamera, but for this "challenge" I used a modified Canon RP color camera (with H-alpha filter) and shot with the 1st quarter moon 83° away in the sky.
For size comparison purposes, the full moon has been superimposed at the same scale. The lunar image was taken just before the lunar eclipse (Moon in Earth's penumbra) last month on the same equipment (minus the H-alpha filter) -- 1/250 sec. @ ISO 200.
Note: The H-alpha shot of S-147 appears red out of the camera, but was converted to b/w to make it easier to see on screen. The Moon shot is a full-color shot.
