P Cyg with ESP spectrograph

[Olivier GARDE]

Here's a two graphs of P Cyg : one with Hydrogen lines up to H delta, and a second with HeI lines.
The lowest magnitude that I could do at this time (mag. 4,76) with the ESP spectrograph (R=30000) and a 16 inches telescope

A gaussian filter was aply because of some noise in the blue part of the spectrum of some of them.

Hi Olivier,
your new spectrograph delivers excellent spectra.
Concerning the HeI 6678 see my summary of almost 10 years observation period.

It would be great, if you could take spectra further for that monitoring

Best wishes,
Ernst

Hi Ernst,

No problem, I have also HeI6678 spectrum of my last observation.
I will send you the spectrum as soon as possible.

Best wishes.
