Galactic Supernova Remnants Images of SNR Optical Counterparts

 

The sky around the Milky Way is rich with Supernova remnants (SNR). Some famous and regularly imaged, such as the Veil Nebula, others are less common but still imaged by amatuer astrophotographers, e.g. CTB1.

There are hundred of other remnants in the scientific literature which are visible in radio, x-ray and other non-optical wavelengths. Many supernova remnants have no optical counterparts. However, there is a rich vein of faint optical counterparts for some of these supernova remnants - unfortunately these are neglected by amatuer imagers.

Here I have collected all my images of supernova remnant optical counterparts. These range from some familiar images, through to some really faint ones which have few or no other dedicated amatuer images. Many have been found by taking speculative images of the objects with no idea what I am going to see.


 

The Galatic supernova remnant references are related to the galactic coordinate system.
