Tanks a lot Paolo
That's great and very informative!
More later
Ciao!

Re: R Aqr spectra requested by Margarita Korovska
Approximative size of the hole of eshel (50 mcm) with my setup
Autoguiding RMS < 1 arcsec
So I can't get the jets shown by your image
It should be interesting to get an image with the slity aligned with the jets

Re: R Aqr spectra requested by Margarita Korovska
Hi François, the narrow slit (31 micron) should be on the jet now (PA 35°, for the large slit observation it was at 15°).
The Doppler shift is appreciable on the 2d spectrum. The north-east "lump" is noticeably redshifted on the oxygen line.
The result:
A detail of the slit position:
Perhaps I should try with the 2400 l/mm grating to increase the spectral resolution (but I don't know if the SNR is enough). Also try to observe H-alpha line.

Bonjour, J'ai essayé une observation sur la région H-alpha de la même manière que Paolo, mais avec une grating de 1800 l / mm et une fente de 50 microns. Voici le spectre 2D et son profil. Umberto

Here is a very late (14Oct17) Ha Spectra of this interesting star I got with the LhiresIII:
I'll try to get one more before the object get to close to dusk!

Nice Spectrum James
The line is [N II]6584 and you have the other line of the doublet in the blue of H alpha ([NII] 6548)
Remember to send me the spectra for the database
All the best,
François

Re: R Aqr spectra requested by Margarita Korovska
A spectrum taken with very bad weather conditions (fog, wind, humidity), just 2x1200s exposure not enough with an eshel spectrograph to have a good SNR in all orders.
here's the H Alpha region, H Beta and HeI 5876.
François, I don't know if this spectrum is enough good for the database....
