Default OG spectra of Cygnus/Lyra

I've posted at

http://home.freeuk.com/m.gavin/ogspec.htm

some new spectra of stars in Cygnus and Lyra via small prism before a
camera lens coupled to CCD. Surprisingly despite the very low
spectral resolution, emission line Wolf -Rayet stars and red Mira type
stars pop into view.

I used to have a scope that made stars look like that ;-) Nice catch
Maurice!
You could make an animated colour screensaver version - very restful ;-)
