A couple of Wolf Rayet star spectra

Hi all,

I have remounted my cheap diffraction grating (only 20Euro and it is even
blazed!) closer to my long exposure modified surveillance camera to see how
deep I might be able to get. My first target to try it out was a couple of
Wolf Raynet stars (WR 135, 140) nice and easy around mag7-8 but spectra down
to mag 12 were also visible. This is fun!
