Spectroscopy, from initiation to performance
TimeBox II is a simplified- and equally accurate - version of the original TimeBox, which has been in the Shelyak catalogue for several years. It is considerably cheaper, and this is something that is likely to radically transform observations of stellar occultations....
By Olivier Garde The Calern plateau, near Nice, is a site of the Observatoire de la Côte d'Azur, which is home to, among other things, the C2PU (Centre Pédagogique Planète et Univers) with 2 twin 1m-diameter telescopes. Every year since 2017, with the 2SPOT team, I've...
How did a team of amateur astronomers become co-authors of an internationally renowned scientific publication?An association of amateur astronomers 2SPOT[1] is a public-interest scientific association created in 2019 by five amateur astronomers (Stéphane...

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....
By Guillaume BertrandI 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 the...
UVEX is a multi purpose spectrograph allowing spectra to be performed in the near IR and near UV domains but also on weak targets.
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.

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.
