Why don't we see this supernova remnant with our telescopes or even AP equipment, like the bright Eta Carinae, or the Veil Nebula ?

Chandra is an X Ray imaging platform.
Their short wavelength means most of them dont make it through the atmosphere too well

Plus not many amateur imagers using XRay sensitive cameras !
