This spectra image covers roughly entire visible region. The image was focused around Mg triplet, seen around the center of the image. R and B ends are clearly out of focus.

This spectra was taken during initial calibration and first light testing of my Spectra L-200 low res spectroscope. Image train was Takahashi FSQ85ED, Vixen flip mirror box for pointing, Spectra L-200, SXVR-M26C CCD camera. Telescope was pointed through a window towards thin cloud deck covering most of the sky. Sun altitude was around 20 degrees above horizon.
