Re: NEW NOU_T ECHELLE RESULTS
Hi JG,
It looks like there is a lot of light lost by the grating. I see it is 217 l/mm. Is that the Baader grating ? I think they claimed a very high maximum efficiency (80% ?). Was the blaze in the right direction ?
Cheers
Robin

Re: NEW NOU_T ECHELLE RESULTS
Hi Robin,
Yes, you're right, this 2" with 217 l/mm. transmission grating is from Baader. Really it was a pity that they discontinued it.
I don't find much difference of sensitivity between, the NOU_T, ( with prism F2, Nikon 85mm. and direct to telescope ), than the MUSSOL, ( with transmission grating, Ashai Pentax 85mm. and optical fiber ).
In that precedent comparation picture the NOU_T his been transformed in the NOU_58 with one Not-NIKKON 58mm. F1.2.
In the NOU_58 the theorical sensitivity, increasse more than 100%, but R, it's only 8500., you can choose..
Friendly, Joan.

Re: NEW NOU_T ECHELLE RESULTS
Hello at all,
You know that the observations campaign for the Helium 6680 in Del Sco is being continued.
I show here couple of results, I would encourage to some of you, very good observers, with instruments with R6000 or more, to observe this region in Del Sco and send your graphics to E. Pollmann.
How you know, the series of integrations must have the most possible high level of signal in this Helium region.
Certainly these type of observations are a challenge for an observer and un good test for their instruments. Do you dare ?
Cheers, J.Guarro.

Hello,
At last, I have be able ot observed the C/2020 F3 (NEOWISE), I leave here two testimonial graphics, they have made with the, ( is it old today ?), ATIK 460EX CCD.
A question, someone remember have saw a strong Na emission in C2020 F3 than in others comets ?
Regards, JG.

Re: NEW NOU_T ECHELLE RESULTS
Hola Joan,
Nos podrías proporcionar los archivos .fit de los perfiles de los espectros de la cometa, quisiera compararlos con los de baja resolución que hice.
Muchas gracias de antemano

Bonsoir Hubert,
I have left here,
https://drive.google.com/file/d/1eo7z16 ... sp=sharing,
for you and for all who are interested, four Fits of the C2020 F3 (NEOWISE), two of them, ( *-Sun_*.* ),they are with the Sunlight subtracted.
I hope that they will serve you for something. I don't use often the Google Drive, if you have some problem with it, please tell me it.
Bien cordialement, Joan.
