Spectroscopy, from initiation to performance
At the end of this article, you will find the different presentations made by the course leaders!August 8th arrival at OHP Great day to plant setups at the Haute Provence Observatory. Amidst rosemary, myriads of little white snails and other small creatures, I arrived...
When looking to upgrade from my LISA in 2020, the UVEX had much to recommend it. Its ability to access a broad spectral range was important as was the flexibility to both adjust the grating angle and to swap over gratings to shift between low and mid resolution....
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...
2SPOT: a spectro setup in ChileBy Olivier Garde, Pascal Le Dû, Lionel Mulato, Thomas Petit, Stéphane Charbonnel© Deep Sky Chile spotSince the 2000s, many amateurs have been installing remotely controllable telescopes on sites in Chile in order to compensate for the...
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.
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).
The very first tests of the UVEX prototype produced by Shelyak Instrument.
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.
