Hi Ken,
 
Don't forget that in a Littrow design you have to squeeze two beams through the same lens and they have to be slightly offset which needs a slightly wider aperture. Also the length of the grating is important at high tilt angles as well as the width. If you look at  the LHIRE optical layout you can see what happens

Subject: Re: [spectro-l] Re: New telescope advice

I thought, as per the Shelyak LiHires description that the collimating lens used in the LihiresIII was a 30mm fl 200mm lens. This appears to give a clear aperture of 29mm so effectively a f6.7. The gratings sizes seem to bear this out? At f10 the exit pupil would be 200/10 = 20mm... I agree the webpage states "f8 to f12"

Hi Ken,

The Lhires III is 'usable' in the f/8 to f/12 range but optimised for f/10 (not f/8).

Robin,
Understood. This angular off set ( about 2 degrees) is taken into acount. Where I went wrong was the size of the grating in the HiresIII, I thought from some of the early drawings I saw that it was a 30mm grating.
The 25mm grating size now makes everything clearer.

Hi Ken
 
Not sure about the latest model but the original holders could take up to 50x50 which is why Lothar was able to fit a larger grating to go to f6.  With my f9 VC200L I use a 25x50  2400 and 25x25  600 and 150 gratings

Hello tous,

Un message rapide pour vous informer que Philippe Stee (Obs. de la Cote
d'Azur) vient de mettre en ligne sur ArasBeam une demande d'observation
(urgente...) de Gam Cas pour calibrer des données CHARA/VEGA.
Vous trouverez les infos sur http://arasbeam.free.fr/?lang=fr

ArasBeam est maintenant ouvert à plusieurs auteurs (dites-moi si vous
voulez en faire partie). L'activité du site va donc s'animer (chouette ! ).

Pour info, Il y a aujourd'hui 9102 spectres amateur dans BeSS / ArasBeam !

Amicalement,

Bonsoir,

Les caracteristiques d'une calibration lineaire decrite par Lambda=a+b*pixel
sont stoquees dans les mots clef suivant :

crval1=lambda au pixel de reference
cdelt1=dispersion
crpix1=pixel de reference

La longueur d'onde se calcule donc relativement par rapport au pixel de
reference soit :
Lambda(pixel)=crval1+cdelt1*(pixel-crpix1)

Cependant, il semble que tous les logiciels ne lisent pas de la meme maniere les
profils de raies calibres. Un exemple avec le spectre du neon au 1200 t/mm et
KAF1600 avec Specview (NASA), Midas (ESO) et SpcAudace (AUDE). Voir images
jointes.

On constate que Midas et SpcAudace donnent le maximum de la raie du neon calibre
a la bonne longueur d'onde (6204.25 A) tandis que Specview a un pixel (0.34 A)
de decalage.
Donc a-t-on Europe 2, USA 0 ?
Valerie, Christian, any comments?

Je joins le profil au format fits gzippe.

Hi Philippe,
correspond your requirements, attached you can find three current spectra of gamma Cas.
Hope they will help for calibration process in CHARA.

Un probable nouvel objet de type FU Orionis vient d'être découvert.
Il est à mag V = 12,6, avec une raie H alpha en émission. C'est faible mais à la
portée d'un star analyser. De plus la circulaire précise qu'il peut contiiernuer
à augmenter en luminosité. Peut-être sera t-il alors accessible en basse
résolution? A suivre ...
Bonnes observations

We report the discovery of a possible FU-Ori-type eruption.  The object
<a
href='http://nesssi.cacr.caltech.edu/catalina/20091110/911100070334153394.html'>\
CSS091110:060919-064155</a>
located at R.A. = 06h09m19.32s, Decl. = -06d41'55.4" (equinox 2000.0)
and coincident with the infrared source IRAS 06068-0641, was   detected
by the Catalina Real-time Transient Survey (CRTS) on 10 November 2009.
It has been continuously brightening   from at least early 2005 (when
it was mag 14.8 on unfiltered CCD images) to the present mag 12.6, and
may possibly   brighten further.  On recent images a faint cometary reflection
nebula is visible to the East. A spectrum (range   350-900nm) taken with the
SMARTS 1.5m-telescope on Cerro Tololo on 17 November shows H-alpha in emission,
all other   Balmer lines and HeI (at 501.5nm) in absorption,and a very strong Ca
II infrared triplet in emission, confirming   it to be a young stellar object. 
The object lies inside a dark nebula to theSouth of the Mon R2 association,  
and is likely related with it.

J'ai fait l'acquisition d'une Watek120.
Elle fonctionne bien avec le logiciel de capture fourni avec le grabber (Ulead
videostudio). L'image est très belle. Donc normalement,pas de problème avec la
caméra, le grabber et le pilote

Mais lorsque je lance la prévisualisation dans Iris (j'ai essayé également avec
audela), le système plante. Au redémarrage j'ai l'indication "le système a
récupéré d'une erreur sérieuse".

L'un d'entre vous a t-il des idées sur l'origine du problème ou la façon de le
résoudre? Y a t-il des réglages à faire au niveau pilote ou dans iris? Pour le
moment je n'ai touché à rien. Juste lancé la prévisualisation (qui par ailleurs
fonctionne correctement avec une webcam)

Merci d'avance pour vos réponses.

Bonjour à tous,
Voici quelques temps que j'utilise une feuille excel pour calculer le profil de la transmission atmosphérique et prendre en compte des paramètres tels que l'altitude du lieu d'observation, la distance zénitale de l'astre ou encore le AOD. Cette démarche fait suite à une excellente note technique écrite par Christian Buil sur le site ARAS (utile en spectroscopie basse résolution).
Lors d'Explor' Espace à Mandelieu j'ai eu l'occasion de discuter avec les "Nice People" et plus particulièrement avec Pierre Dubreuil. Ce dernier s'est proposé de coder mon tableau excel et d'en faire un petit exécutable que nous vous proposont à l'adresse ci dessous:
J'espère que vous en ferez bon usage.
Bon ciel
Eric Sarrazin, Pierre Dubreuil
 
PS1 : Valérie y a t il une possibilté d'ajouter une petite icone dans Vspec pour lancer le logiciel?
PS2 : François (Cochard) Cela mérite il un petit sujet sur Arasbeam?

    According to CBET 2050, Itagaki-san has discovered a bright (8.1 mag)
eruptive object in Eridanus (position 044754.21 -101043.1).
Although this object has been suggested to be a possible nova,
the object might also be a WZ Sge-type dwarf nova.
Spectroscopic and time-resolved photometric observations are urged.

Hi Eric, Torsten

Have you reported your results, eg to observations@...
These could be the first spectra of this object. I do not think they look
like the spectrum of a dwarf nova in outburst

Bonjour à tous,
J'interviens pas très souvent, mais quand ça cause technique info... c'est pour
moi :-)))

Voir la page :
http://www.mecastronic.com/installation_grabbee.htm
C'est un problème d'installation du pilote.

Cordialement.

J'ai fait l'acquisition d'une Watek120.
Elle fonctionne bien avec le logiciel de capture fourni avec le grabber (Ulead
videostudio). L'image est très belle. Donc
normalement,pas de problème avec la caméra, le grabber et le pilote

Mais lorsque je lance la prévisualisation dans Iris (j'ai essayé également avec
audela), le système plante. Au redémarrage j'ai
l'indication "le système a récupéré d'une erreur sérieuse".

L'un d'entre vous a t-il des idées sur l'origine du problème ou la façon de le
résoudre? Y a t-il des réglages à faire au niveau
pilote ou dans iris? Pour le moment je n'ai touché à rien. Juste lancé la
prévisualisation (qui par ailleurs fonctionne correctement
avec une webcam)

Merci d'avance pour vos réponses.

François Teyssier

Hello all,


For your information, a thread on the Swiss Astronomical Group (SAG) regarding echelle spectrograph which has been recently pointed in another spectroscopy newsgroup.

Regarding the use of an echelle spectrograph and our off-the-shelf eShel, I would recommend Christian Buil overall review of his eShel: http://astrosurf.com/buil/eshel3/review.htm

Have also a look at our work on exoplanets:

Here is an interesting thread concerning echelle design of an amateur 
spectrograph.
http://tinyurl.com/yhexghr
It is a (google translated) thread from the spectroscopy section of the 
Swiss (SAG) forum. it addresses some of the design issues and also includes 
links to relevant threads on the VdS forum.

Thanks Robin for that email adress. I did report that observation this morning.
Let me know if you have any informations.
Clear skies

Salut!
Juste une petite page pour vous raconter comment une fausse raie d'émission
aurait pu s'inviter hier soir sur le spectre de la possible nova dans Eridan.
http://e.sarrazin.free.fr/spectro/anim_nova_eridan.htm
Donc mefiez vous des étoiles!
A+
Eric

Hi!
Just a small webpage to let you know how a star might have been transformed into
an emission line on the yesterday possible nova spectrum.
http://e.sarrazin.free.fr/spectro/anim_nova_eridan.htm
Regards
Eric
