Hi,
Yesterday I observed again WR 134 (HD 191765) but this time I made 2 images with each 1800s. I had no problems guiding my mount for that long time.
Telescope AT 8"RC with LISA 35µ slit and QSI520i CCD camera.
Interesting outcome is that I got a smoother continuum and was able to detect lines which I did not have in the run of 6x 600s. The 2 Sodium D2 and D1 lines are well defined and also for the first time there seems to be some info on the 5696A. (¿ Does WR 134 have emission there ?)
Below my results
Here my original image *.fit 2.5MB file as well as a *.dat file at 2.949A dispersion

and here the comparison of Christian's profile with mine
Thanks for reading, looking and comments
