Spectrum obtained August 21, 2015.

Two cameras were in action. One employing a 8 mm fish-eye lens, the second dslr was equipped with a 15 mm fish-eye lens holding a diffraction grating. As described in the caption below.

A cropped section of the image obtained through the 8 mm fish-eye lens. Exposing the field at the same time as the meteor was captured through the diffraction grating. Unfortunately some dew on the lens. Therefore not top image quality.
