Dear colleagues! In the attachment you can find my Halpha-monitoring of the star PCyg, with participation of different observers. Are there measurements from...
Hello everybody! On the webpage given below you will find a call to observe the Be star HD 6226, which is in outburst. Sur la page web indiquee ci-dessous,...
Une petite distraction solaire entre deux observations de Be (Coralie, j'ai fait deux fois HD6226, je tache de dépouiller vite !). J'ai visé notamment les...

Bonjour. Je sais que le spectro LHIRES III a été conçu avant tout pour la haute résolution. Néanmoins, en utilisant la feuille de calcul ETCL disponible ...
La question est très interessente mais il est difficile de trancher de manière ferme sur la réponse, comme tu le pressent. Tout d'abord Jean-Pierre, ton...
Bonjour, Comme vous le savez certainement, la souscription pour le nouveau spectrographe Lhires III a démarré il y a deux semaines. Il est temps de faire un...
What is the maximum width of detector which can be used? For example will a DSLR produce a good spectrum across the whole width of the CCD? Thanks Robin...
Bonjour, Une requete pas tres banale sur cette liste, mais si qq avait le spectre d'une lampe genre flash photo entre 400 et 900 nm, ca serait super. Merci...
Hello Robin, Not easy to calculate this. Attached is one sample of a solar spectrum (30sec exposure wih a EOS300D Cano Digital Revel SLR) around 5100A. I ...
Hi all, The width is limited by the doublet optical aberrations. Spot diagram analysis shows a valuable linear field of only 8 to 10 mm. Some degradation and...

While I assume extra gratings for the Lhires III can be purchased at any time from Edmund or Optometrics, will it be possible to order extra grating supports...

Hi Bernard, I believe it all depends on whether the group can identify a manufacturer willing to do any additional production runs, or whether a start-up...

Stephen, Probably very good advice to order now. While I do have a small mill and lathe the machine drawings are not yet on the website (I couldn't find them),...
Hello Bernard, You are right, one can order additional gratings easily from Optometrics anytime. For the supports, we do not plan to make them available but as...
Hi Bernard, Re: the neon lamp holder, you are indeed correct. The kharki coloured rod in the drawing supports a silver coloured lamp holder, which can swing up...
The LHIRES website mentions guiding using the light from target star which overlaps the slit "An algorithm has been developed for guiding on the halo (blurred)...
Hi Robin, I believe this is still work in progress, and something that Christian is developing, so I'll leave it to him (or Olivier) to respond. To my...
Bonjour a tous, Le spectro Lhires III arrive ... Et il y a peut-etre des gens interesses par une camera pour le suivi. Il y a la WATEC WAT-120N ... Chez...
