Bonjour Christian,

Other time, you have open new trails for the amateur spectroscopy. That is a good stimulus to us, above all a new and young observers.

Talking to about UVEX, I suppose that will be more professional analysts interesset in that type ofservations, it would be a good to us, the observators. What are you thinking about it ?

The difference between UVEX2 and UVEX3, is only the cylindrical lens inclination ?

Many thanks for your great job and effort.

Bien cordialement, Joan.
