Encore bravo Marian

Re: Premiers spectres : P-Cygni et WR136 (First spectra !)
Hello Marian
Felicitation. Cela m'a l'air maitrisé. Peux-tu nous envoyer un liens vers tes fichiers "fits" ?
Je reconnais bien WR136. Le continium est bien. Une legère pente décroissante vers le bleu. Un objet très froid donc.
Je l'avais observé en 2013 ici: https://perso.crans.org/lemoult/spectro ...

planetary nebula NGC 7027
Hello
At OHP summer 2017 star party, i get a low resolution spectrum of NGC7027. It's small 14 arcsec diameter, but very bright.
A very rich spectrum, i put some legend with the help of : https://arxiv.org/abs/astro-ph/0507155

Re: CMOS vs CCD for spectroscopy applications
Hello Christian
Very impressive work. I really love your article. Thank you.
In case of a spectro with fiber, we can put in in a fridge. Perhaps you can try to put a CMOS camera at -20°C ambiant (in a fridge) to check the dark of detector at @-45°C. And also check is the camera still work at such ...

Re: Use of CMOS detector for faint object spectrography
Hello
Whaou, 1.1e- de bruit de lecture ! Bravo Christian pour ces avancées.
Je pense aux spectres de NP super faible... Cela pourrait être bien a condition d'arriver a concentrer le flux sur les petits pixels.
Lors de notre mission a saint veran sur le NP, on utilisait le LISA+ATIK460 en bin 2x2 ...

Re: WR140 aproaching periastron
I got a spectrum tonight of WR140. With eShel R=11000, ATIK460, Celestron C14.
But i forget who collects these data ?

Re: Statut de HD 9878 [Be]?
Hello Thanks for these spectrum. A congratulation to Yolande and Gérard.
I will integrate these spectrum soon in the ARAS dedicated page here http://www.astrosurf.com/aras/be_candid ... idate.html

Re: 28 CMa outburst
Hello
I took a new spectrum of 28 Cma last night and the night before. The Ha emission continusly increase. Relative continuous: more than 5 unit now.
LHIRES 2400T, Telescope Newton 200mm. R=17000. From Abu dhabi, lat=25°N. This star is high is the sky. Alt=35°

Nice finding Paolo. I just updated the page http://www.astrosurf.com/aras/be_candid ... idate.html with this new possible Be star.

Re: Collimated scope :-)
Hello
De même de mon coté, les led IR de mes cameras restent allumés. Cela crée un très léger pic vers 800nm avec le dôme fermé.
Mais je ne crois pas l'avoir vu avec le cimier ouvert, et le télescope qui regarde le ciel.
