Alpy 200 : a “newcomer” to the Shelyak Instruments range
It's always a pleasure to announce a new instrument in our catalog, but this pleasure is increased by the fact that this instrument has been widely requested and even suggested by several observers. It was Robin Leadbeater - many years ago - who first alerted us to...

Remote Spectroscopy – the UVEX Motor Unit
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....
Sol’Ex & Star’EX: a new way to approach astronomy
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...

Sn 1181, an unusual story …
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.
RS Oph : the contribution of Shelyak spectrographs
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).

How to choose your autoguiding camera in 2020 ?
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.
