Dobsonian binoscopes

To Dutch page   

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 one big mirror.

These binoscopes are the end product of a long time of experimenting with aspects that I consider critical for a Dobsonian telescope or binoscope. Such aspects include rigidity of the structure, stability, easy collimation procedures and simple means to merge images.

Recently, I have published a few articles in Amateur Astronomy Magazine on these subjects.
- One article looks into the scientific background of binocular vision.
- Another reports on measurements to compare a binoscope with a mono-mirror Dobsonian telescope. The conclusion is that when observing extended objects, one can see MORE with a binoscope than can be expected by simply adding up the surface areas of the two mirrors.
- Finally, a third article addresses the merging of images in a binoscope.

These articles can be found in the header of this page.

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.
