Re: Atelier en ligne STAROS : découvrez des outils innovants pour la spectroscopie
Je n'ai pas une vision radicale, ce n'est pas mon truc, et je n'oppose pas la technique et la science que l'on peut faire avec. Oui, il faut une finalité, mas attention, cette finalité n'est pas obligatoirement de faire de la "science", un mot qui fait peur auprès de certaines personnes (à...

Re: T CrB before its new nova event
A high-resolution Star'Ex spectrum (R=19 000) made on June 13th from Antibes and like Guillaume B, using a small diameter, here an 80 mm Askar scope (model PHQ), all on an AM5 mount, and managed via ASIAir (except for the spectra storagel under Prism): http://www.astrosurf.com/buil/forum28/_tcrb_202...

Re: fits-keywords for STAROS database and SpcAudace
The next update will offer greater flexibility. For example, BESS_ESPR will be optional. Please note, however, that it is primarily up to the software designers to ensure that the data produced is as compatible as possible with the analysis applications (BESS, STAROS, ...), and not the other way rou...

Re: Test new configuration
It is indeed an artifact in one of the images of your spectrum (a badly corrected hot spot ?). It is not critical at all. Look at your 5 images one by one and you may find the origin. It is very easy to see that this is not a real line: the thinnest physical lines that can be observed are the tellur...

STAROS spectral data base
I announce the official launch of the STAROS public spectral database: https://staros-projects.org STAROS is a database whose originality is to address observation campaigns on an object at a time and for a limited time. For example, an observation project can be opened to follow the news (nova expl...

Re: La spectrographie 2.0
Joan, Your questions are interesting and normal. My goal here is mainly to draw the attention of observers who use equipment that is not necessarily very expensive, but efficient, because it corresponds to the new technology. This is the case of astrophotographers: it doesn't take much to be able to...

La spectrographie 2.0
Un point de vue sur une autre façon de pratiquer la spectrographie aujourd'hui : moins chère, plus simple, plus ouverte :

Re: La Comète du début de l'année : C/2022 E3
Quelques spectres de C/2022 E3 obtenus à diverses résolutions. Sur celui pris avec spectrographe Star'Ex équipé d'un réseau de 300 t/mm et monté sur un petit astrographe de 60 mm de diamètre seulement, on peut apercevoir des raies H2O+ (une première pour moi), Elles se forment assez loin du noyau et...
