Christian, This is a very nice and impressive result. I plan to do some investigations this summer of what radial velocity precision we can achieve with...
Hi Eric, (Sorry about the blank message- finger trouble) I would be intesterested in what you can achieve. There has been some discussion about this in the...
Hi Robin, ... Yes, this is what I suspected as well. Can you summarize those discussions more quantitatively? Do you get down in the few km/s range, or is...

Absolutely, the calibration source is essential. The Thor / Ar is really perfect (I think that Shelyak can provide such a system and adaptation to Lhires III...

... Hello, their are many effects who can affect the precision : the mecanical flexion is of course the most important source of error (and the LhiresIII is...

Mes plus sincères compliments, depuis toujours je t'ai eus par pionnier et un maître. J'attends que tu puisses continuer à ouvrir de nouveaux sentiers. ...

Bonjour, J'ai un copain qui me dit que le LhiresIII n'est pas adapté pour un gros télescope, genre 520 f/d=3.3, est-ce vrai? Il m'affirme que je ne gagnerai...

Bonsoir Il a raison, le Lhires a été calculé pour un instrument ouvert à 10. Aussi pour un instrument ouvert à 3.3 il suffit de rajouter un barlow de 2.5,...

Beautiful to watch a craftsman at work, especially for someone from the valve (tube) era like me. Perhaps he can run us off a few Thorium/Argon lamps ;-) ...

Hi Adam, yes, you probably hurt your grating. Only dry air (from an ear bulb) should be used to "clean" a grating. However, while you now have a grating with...
