Eastern Veil Nebula
NGC 6992, NGC 6995, Caldwell 33 · Supernova remnant in Cygnus
- Magnitude
- 7.0
- Size
- 60′ × 8′
- Effective surface brightness
- 22.4 mag/arcsec²
- Best months
- Jul, Aug, Sep
- Declination
- +32°
- Filter
- 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.
