Hi,
Tried my Luck yesterday with this star. It is a stacked image of 20 subexposures each with 120s. Taken with the LISA on an AstroTech 8" RC reduced to f/5.
Is it correct ? I can only Identify the H-Balmer lines. Are there some He lines too ? Also if I compare my profile with a pro reference file B2i then at the blue end it is totally different. Is this OK ? I used Sadr in order to get my CCD response.
My dispersion is 2.952A/px
Thanks for looking and comments are welcome.
