Veil Nebula

The Veil Nebula is the remnant of a supernova explosion that occurred thousands of years ago. At its peak, this supernova would have been magnitude -8, thirty times brighter than Venus ever shines. Left behind from the explosion are the wisps, streamers and filaments of delicate nebulosity that form dual arcs surrounding the star 52 Cygni. This is my second attempt at a widefield image of this nebula.   My previous image was taken with an unmodified Canon DSLR.   You will see much less red in that image, as the unmodified cameras are not sensitive to the spectrum of light emitted by ionized hydrogen (HA).   This image is much shorter duration (less than an hour, compared to over 7 hours).   This is a testament to the much higher sensitivity of the modified camera. You can also see a closeup of the Eastern Veil Nebula here, taken with a dedicated astronomy camera.
