Image Details:

This is a series of high resolution spectra combined into a mosaic. The images were taken through an ST-237a imager attached to a reflection grating spectrometer with 1200 lpi grating. Major lines are marked along with their wavelengths in Angstroms. Each integration was 5 seconds duration and had a dark frame subtracted. 17-March-2005.

The spectrum below was taken with the Shelyak LISA spectrograph by aiming at blue sky. Processing was done in Demetra.
