Explanation: There is a quiet pulsar at the heart of CTA 1. The supernova remnant was discovered as a source of emission at radio wavelengths by astronomers in 1960 and since identified as the result of the death explosion of a massive star. But no radio pulses were detected from the expected pulsar, the rotating neutron star remnant of the massive star's collapsed core. Seen about 10,000 years after the initial supernova explosion, the interstellar debris cloud is faint at optical wavelengths. CTA 1's visible wavelength emission from still expanding shock fronts is revealed in this deep telescopic image, a frame that spans about 2 degrees across a starfield in the northern constellation of Cepheus. While no pulsar has since been found at radio wavelengths, in 2008 the Fermi Gamma-ray Space Telescope detected pulsed emission from CTA 1, identifying the supernova remnant's rotating neutron star. The source has been recognized as the first in a growing class of pulsars that are quiet at radio wavelengths but pulse in high-energy gamma-rays.

Here is my supernova explosion. This is combined data reprocessed from two separate imaging sessions.
This is part of the eastern Veil Nebula, the remains of a supernova, a cataclysmic explosion of a massive star that detonated about 8,000 years ago. This nebula is located about 1,450 light years from earth.

Nice! What kind of camera did you use, a dslr, or ccd? I have a Player One Mars-C, but it’s forte is planetary photography.

This shot was taken with a consumer grade unmodified Cannon 60D.

Great job! I’m just a beginner, photographed the Sun a few times. The software has a bit of a learning curve.

Yep, processing the data to pull out as much as possible can be very tedious. A whole new realm...lol

This is my image of the Veil Nebula. 123 images X 3 minutes each stacked and processed in Siril. Nikon 200mm lens with a dedicated astronomy camera.
