Wolf Rayet stars

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

WR 1 type WN4B HIP 3415
WR 4 type WC5+? HIP 12527
WR 5 type WC 6 HIP 13380
