Bonsoir, Les images dont je parle dans ce topic sont présentes sur ce lien : http://www.astrosurf.com/charbonnel/Images/Forum_ARAS/Lisa_Reglages/CAPH.zip . Depuis plusieurs belles nuits, je tente tant bien que mal des réglages de LISA !! Mon instrumentation : LISA + tube optique (dit "cul de bo...

Hello, You can find an animation of RR Lyr last night at http://www.astrosurf.com/charbonnel/Traitements/Spectro/RR_Lyr/2012_08_13.gif Treatments and animation with ISIS. Acquisition with PRiSM. Place : Observatoire de Haute Provence. Instrument : Meade 12" on Losmandy TITAN + LHIRES III 2400 t...

Hello, I have tried this star when I wait a FS Cma was more high in the sky. With : T500 + ESHEL : http://www.astrosurf.com/charbonnel/Traitements/Spectro/ARAS/T_Crb/T_Crb.png You can find more detailed spectrum at http://www.astrosurf.com/charbonnel/Traitements/Spectro/ARAS/T_Crb/_tcrb_20120401_918...

Hello, I send you two graphes. Instrument : T500F6 Eshel#112 ST10XME Site : Durtal(UAI949) Last night : 24/03-> 25/03. First is an extract of 30 min with a serie of spectra around Halpha (order 34). Exposures are 200 seconds (Star is very low at this time). I can notice no variation : http://www.ast...

Hello,

Tonight at UAI949 :
LHIRES : V351 Per. More later, I will image Lam Eri.
ESHEL : WR4. After, I will image FF Cam and FS Cma.

I hope clouds already on atlantic coast will be patient !

Stephane

Bonsoir,

Au programme de ce soir pour le moment :
LHIRES 2400 autour de Halpha : FF Cam, 28 Tau, Zeta Tau, Eps Aur. Reste à faire : de la Be rouge !
ESHEL : V777 Cas, Zeta Tau, et 2 FS CMA : AS78 et MWC 158. Reste à faire : IRAF 0780

Bonne soirée
Stéphane

Hello, I could write « Who are interested by time of telescope ? » ... I just would like to know if it could be add a directory topic of different objects that can be “useful” for everyone which makes analyses. For example, I have not observed from a long time (bad weather with a lot a low clouds) s...

Hello, I try to push Eshel to orders 30, 31 and 53. In order to obtain these extreme orders, I must use a 600sec spectrum of Alpha Del instead TUNG+LED. With this last, I cannot obtain orders 30, 31 and 53 because signal is very faint (I use ISIS). To obtain these extreme orders, I don't want always...

Olivier,

J'en suis tout à fait conscient !
Ces mesures viennent surtout étayer ce qu'a décrit Christian : qu'il ne faut pas prendre TUNG+LED comme le "vrai" flat. C'est en effet juste pour la détermination d'ordre.

I just would like to add that despite high magnitudes, emission lines are great (but continuum is faint).
I can realise V1972 Cyg without problem with a simple 12". ( slit of 35µm, 3 or 4 x 1200sec with LHIRES III and ATIK314L).
