2001 Aug 14 - a return after 12 months to my favourite spectral targets - the Wolf-Rayet stars in Cygnus.  A one hour session went like clockwork with results posted here 10 hours later [after some sleep!]. Nine duplicated spectra [5s and 20s exposures] via the 30cm SCT at f/6.3 with the Rainbow Optics grating placed immediately before the MX9 CCD yield a low dispersion of 50A/pixel.

See  Wolf-Rayet#1 and Wolf-Rayet#2 for more on these exotic stars.
