Remote Spectroscopy – the UVEX Motor Unit
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...
Spectropolarimetry or how to observe the magnetic field of a star with a 72mm telescope and a 3D printed spectrograph
By Guillaume Bertrand I started astronomy at the age of 15, in 2003, with the opposition of Mars. I quickly joined the astronomy club “Village du ciel” based in Vendée to exchange with other amateur astronomers. My first instrument was a 114/900, I got all...
UVEX : Extreme spectra
UVEX : extreme spectra By Olivier Garde Introduction Through this article, I will show we can do extreme spectra in the near UV and the near IR with a UVEX equipped with the standard 600 gr/mm grating. This allows to obtain resolutions from R = 820 @ 350nm up to R...
Spectroscopic Observations on Beta Persei (Algol)
Spectroscopic observations on Beta Persei (Algol) By Jörg Schirmer I had my first contact with astronomy when I was 10 years old when my grandfather gave me the book “AUS FERNEN WELTEN” by Bruno H. Bürgel from 1920. That probably fascinated me so much that...

UVEX by Shelyak : first light
The UVEX by Shelyak : first light By Olivier Garde I had the opportunity to test one of the two prototypes of the UVEX version made by Shelyak Instruments. This version of UVEX differs from the “3D printing” versions already produced by several teams with...
The twin Quasar
The twin Quasar By Etienne Bertrand (Etienne Bertrand) I have been practicing astronomy since 2008. Having not studied, it was through leisure and reading that I knew this fabulous field. When I started the observations, I remembered the summer nights spent looking at...
