Hi,
Finally found a workflow in order to get this elusive stars into the center of the slit of my LISA mounted on a TOA 130 @ 600 mm focal length and imaging with a QSI 520i B&W CCD camera.
All spectra are esposures of 300 seconds except HIP 3415 which is a stack of 20x 180 s and 7x 300 s exposures.
All fit images were processed in PixInsight using DARK and BIAS frames. Instrument response was applied in RSpec as a reference file which I developped acording to Christian Buil paper.
Calibration was done using a nearby type B7IIIp star (11 persei).
Thanks for looking as well as comments are welcome in order to improve

Re: Wolf Rayet stars
when the season permits, WR78 and 79 are very nicely close together and bright in the false comet cluster, in the tail of scorpio. I found them serendipitously when doing a spectroscopy demonstration at an outreach night, with a camera and SA100 and drift scaning to show spectral lines more easily. The bright blue line of (i think it was) WR79 was very obvious, then later I noticed there was a second WR star with emission lines in the same frame!

Hi Hamish,
Thanks for the info but my Sky is dead to the South. I have a neighbour with some Palm trees in his garden and I have lost the full south starting at the Celestial Equator downwards South ...
