Hi Adrien,
welcome to IIS
I have a (Stellarvue) binoviewer which i use with a Meade 12"" LB dob, and they work a treat. But the basic binoviewer wouldn't come to focus and I had to use the supplied extension tube. So just be aware that this may happen with yours also. But my god, the views are spectacular
Oh, and a happy birthday btw
Cheers,
