Presenting Crab Nebula, a ‘Supernova Remnant’ – This is the mess that is left when a star explodes. The nebula is result of a supernova seen and recorded all over the world in 1054 AD, is filled with mysterious filaments. A supernova remnant forms when the pressure inside of a star is stronger than the gravity that holds it together, and the star explodes. As the gas rushes outward, it fills the space around it. The material ejected from the Crab Nebula is moving at more than 3 million mph (4.8 million kph). The Crab Nebula spans about 10 light-years. In the nebula’s very center lies a pulsar: a neutron star as massive as the Sun but with only the size of a small town. The Crab Pulsar rotates about 30 times each second.
I have taken this object before, but, decided to revisit to see whether there is a significant difference after couple of small improvements in my set up. I did see clear improvement in average FWHM and therefore the overall picture is definitely better, although, it’s not perfect by any means.
Took this latest picture over 22 hours (51 images of 20 minutes each for Luminance and 11 images each of all 3 colors for 10 minutes each.)
The following image was taken in 2018…. Took this image little over 12.5 hours (15 Luminances of 20 minutes and 10 color images each of RGB of 15 minutes each).
This was imaged at 75 times magnification and then cropped by about 50%.
