Spectroscopy, from initiation to performance
The Sol'Ex project (later followed by Star'Ex) offers a new way of "entering Astronomy": it is an approach that is affordable, simple, fun and fascinating. Here is what it is in a nutshell.Sol'Ex, to startSol'Ex is a project designed, organized and led by Christian...
The TimeBoxUse for asteroid occultation dating. By Daniel Verilhac, amateur astronomerIntroductionThe observation of stars occultations by asteroids is an exciting sport, it allows with few means to contribute to science. It is an excellent playground for amateurs...

At first glance, it is curiosity that motivates any amateur who observes the sky. Sometimes this curiosity is rewarded by acquiring a very beautiful picture or by explaining a physical phenomenon that takes place thousands of light years from Earth, through spectroscopic observation.
UVEX is a multi purpose spectrograph allowing spectra to be performed in the near IR and near UV domains but also on weak targets.
On August 8, 2021, the recurrent nova RS Oph was observed in outburst at magnitude V = 5. The amateur community immediately mobilized to realize many spectra at various resolutions with various spectrographs (with resolving powers R = 600 to R = 30,000).
UVEX, to write a new page in astronomy by François CochardWe are happy to announce the arrival of a new instrument in the Shelyak range. This event is important for several reasons. It's a sign of the dynamism of the astronomical community, which always pushes the...
During my program “Spectroscopic Detection of Interstellar Sodium” I also came across Algol. Because of unclear Na lines, I took new recordings later. I noticed the different position of the HeI line (5875.62 Å) and the greatly changed shape of the Na-D lines.

Timing of astronomical occultations and other astronomical phenomena need to be done in an absolute time scale with a precision of a few milliseconds in order to pull and compare recordings done by different observers around the world.
In astronomical spectroscopy, guiding camera is an important element, since it’s what makes it possible to point the right target (star, nebula, etc.), then to ensure precise guiding to inject the maximum light into the spectrograph slit.

I use the software package AstroPlanner by iLanga, Inc. for my initial planning. I have added approximately 75 stars which contains all the information I need to plan the acquisition.
In this article, I will try to show you that amateur astronomers can achieve remarkable results in the astrophysical study of the stellar world.
