Crab Nebula Spectrum and images
by Richard Crisp
this is something I have been meaning to do for some time. It is a poster showing the spectrum of the Crab plus images taken through four different line filters, [SII], Halpha, [NII] and [OIII]. Finally it shows three tricolor images made by using various combinations of filters.
Have a look if interested
