Hi all,
here´s a compilation of my summers observations of WR-stars, achieved before or after Jupiter planetary sessions. For comparison, I also added a spectrum of the interesting O6e star Lambda Cephei, which obviously shows a He emission line and possibly the N emission at the same positions as the WR-stars. And due to it´s beauty and resemblance, the P Cyg spectrum´s added too!

Excellent work and well presented  thanks for including Lam Cep and more please  The absorption bands [longer wavelength right of H-alpha] in P Cyg and Lam Cep probably telluric eg atmospheric lines A, a and B in reverse order

Maurice, I´m sorry, I didn´t catch that; why in reverse order?
Best regards

Hi,
I revised the version above, adding further and correcting wrong contents.

Fraunhofer lettered lines ordered from red to blue - the reverse of modern convention ordered by wavelength blue to red as your spectra - hence my reference
