Re: New eshel setup in Chile

Hello Bernard, I am Stephane Charbonnel, a member of the 2SPOT Team. It is me who writes script for automatic observations. Automatic observations are done exclusively via PRiSM software. The principle is as follows: 1/ Choice of target in an ordered list or if the list is too long (like the list of...

Re: Probable nova in Hercules mag 6.4 !

As David Boyd write it, it has completly changed from the day before !

It looks like a nova now but already fainter as 24H before.

Re: Probable nova in Hercules mag 6.4 !

Hello, A spectrum among the three taken yesterday during the night with my ESHEL from Shelyak : Resultat_NovaHer.png An image of the field (the object is in the hole and very bright) : Champ_Spectral_Nova_Her.jpg Must be followed. Is it always a probably nova or are we sure it is a nova ? Stéphane

Re: RR Tel spectrum

Hello, The PRiSM's script already exists for my setups. Last week, I have adapted it to our setup : it's now good. But if you haven't already use PRiSM, you doesn't begin by a script. You must learn to use this software manually (as you make at this time maybe with another software) and after begin ...

Re: How to choose a camera for auto guiding in spectroscopy

Olivier,
J'apporte juste un petit bémol : pour un PC moderne, le port ST4 devient de moins en moins nécessaire, les pulses résultant du guiding étant bien gérés maintenant par le matériel moderne (sans être interrompus). Donc la 414EX semble être la remplaçante de la 314L+.

Re: UVEX3 N2

James,

Be carreful filament with carbon is less easy to print than without.
The printer must be closed because the temperature to use it must be high (minimum 280°C of memory) and printer noozles must be higher than 0.6 mm because can clog easily. So be carrefull with 3D cheap printer ...

UVEX 3 : PET-G Fibre de carbone

Bonjour, Voici l'UVEX 3 imprimé en PET-G fibre de carbone : boitier.jpg Il apparaît très mat dû aux fibres de carbone. Attention à bien utiliser une imprimante qui puisse monter à 280°C (et de ce fait fermée de plus pour éviter trop de déperdition de chaleur) ainsi que des buses en rubis pour abimer...

Re: The UVEX project - documentation available

Etienne, pour répondre à ta question : * J'ai déjà acheté les pièces chez Thorlabs : si tu te contentes d'un réseau, tu en as pour 430€ TTC de pièces Thorlabs. Ne soit pas étonné au passage de devoir montrer patte blanche vis à vis d'une commande Thorlabs. Ça reste des américains. * Compter 20€ de v...

Re: UVEX3 N2

Bonsoir,

J'ai pris ça chez Amazon : https://www.amazon.fr/gp/product/B007YD6KVE
6500 K donc je pense pas mal.
J'ai pris la version 110W (équivalent) mais à la réception 2700K ... dommage (et remboursement)
