What’s left when a star explodes
The Vela supernova remnant is what was left over when a star exploded some 11,000 – 12,300 years ago in the constellation Vela in the southern sky. This supernova remnant is one of the closest known to us. In 1968, astronomers at the University of Sydney determined that the Vela pulsar was identified as associated with the remnant and thus was direct observational evidence that supernovae form neutron stars.
My take on the Vela SNR was to take advantage of the combined excellent datasets by Ian Horarth in both RGB (Red-Green-Blue) and HOO (Hydrogen Alpha-Oxygen 3 narrowband filters). The two datasets were downloaded from Telescope.live from their “Pro Dataset” library.
After combining the data and star aligning all of the images and building the integrated the sub-master images, I started by combining an LRGB combination, in this case the Alpha sub-master serving as the luminance component. Then, using the NBRGB (Narrow-Band, Red, Green Blue) Combination script I built the HRGB+H+O+O image.
The end result is the result of a variety of tweaks in Photoshop, including the new raw enhance feature that essential quadruples the resolution of an image. Although the effect is not as dramatic as you might expect, I think it is a useful process.
