Under the name Otte Binoscopes I manufacture and sell Dobsonian binoscopes. A binoscope 'are' in essence two telescopes that are jointed in such a manner that you look with each eye through a separate telescope. In that sense a binocular is a binoscope as well, being two refractors, one for each eye. The term binoscope is, however, often reserved for double Newtonian telescopes with two mirrors.
Why would one prefer to observe through a binoscope? Experienced observers claim that observing with a binoscope is superior to observing with a traditional 'mono'-telescope that has a comparably large, but only a single big mirror. Observing through the binoscope shown below one observer said: ....this binoscope surpasses any of my expectations....
Why is that? This topic is addressed in the section under the header Why a Binoscope.
Also, I have published two articles in Amateur Astronomy Magazine in which I discuss the Why of a Binoscope more elaborately.
Since a binoscope involves two telescopes that produce two independent images which have to be joint together, this asks for a somewhat different approach of collimation etc. These aspects are discussed under the header Merging of the Images. This has also been published as article in Amateur Astronomy Magazine. It addresses important aspects such as rigidity of the structure, stability, easy collimation procedures and simple means to merge images.
Prices are quite dependent on the optics that are chosen and options such as the ServoCAT/Argo Navis tracking system. Please contact me for information.
