Binocular observations with a single arm (single-pole) dobson telescope

The detractors of single arm (single-pole) dobson telescope consider that it is just an aditional telescope, only usable with light oculars, that it vibrates and that the image is not stable... 

Now, it is completely false.

Yes!! This 12" (300mm) travel newtonian telescope is planned for heavy eyepieces associated with typical coma corrector paracorr fromTelevue. In more I use it with one binocular from Televue associated with two Nikon NAV 17.5mm eyepieces, what is about 3.3 lb (1.5 kilos) on lightweight Feathertouch focuser from Starlightinstruments. How it is possible? One of the secrets of the success is the choice of a very stiff high balance point associated with an only big altitude bearing. And naturally, we can use it with encoders and sky commander  able to locate and observe celestial objects. Here, at Beille Plateau in Pyrenees mountains (the 7th november, Ariège -  France).  Thanks to Philippe for photography.
