Dual-band recommended

The brighter, more detailed arc of the Veil. Red hydrogen and teal oxygen filaments interleave; dual-band captures both.

Reachable from mid-northern latitudes (UK, northern US, central Europe) and from the south.

Imaging the supernova remnant

Supernova remnants are emission-line objects, strong in both hydrogen-alpha and OIII, and their filaments are thin, so pixel scale matters as much as aperture. A dual-band filter is essential from any lit sky and still helps under a dark one. These are long-integration targets; plan on several sessions and stack across nights.
