The Whoppshel, a high resolution echelle spectroscope (about R=30000)
Spectro star party OHP 2020 : from 12th to 17th August 2020
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.
Demetra 5.1, new graphics function
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.
Using a Whoppshel spectrograph R = 30000 on a 600mm telescope at the Hubert Reeves observatory in Mars (Ardèche-south of France)
Enhancements of the new version of Demetra 22.214.171.124 Alpy
Retrospective of Spectro party 2019 at OHP, photos, spectra and more…
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.
Workshop au Nouveau Mexique les 22, 23 et 24 février 2019
Spectro Workshop in New Mexico on February 22, 23 and 24, 2019.
Using a LISA spectrograph on a large diameter telescope.
Nearby or in thousands of km, take control of your calibration & flat lamps for Alpy, Lhires III and LISA.
SPOX module : to remotely control the flat and calibration lamps for Alpy 600, Lhires III and LISA.
Realize a spectrum of a very weak object with a LIsa or an Alpy, it is possible.

What about chasing Be stars outbursts this week-end ? All you need is a good spectro !
A doublet “bespoke” to optimize the eShel in the blue
How to use new collimator of the eShel II spectrograph with Audela software ?
AudeLA manages pictures acquisition and then data reduction.
Spectra made with Shelyak spectroscopes were used in a publication on the symbiotic star AG Draconis.
