Telescope Optics

I stopped using astronomical telescopes because I could never get in a comfortable, stable position to use one. I decided to design a better amature telescope, one where you could sit comfortably and never have to move as the telescope tracks the sky object. Here are a few of the sketches. The basic idea is to divert the image from the main lens through the centers of the telescope mount axes and to the eye. The observer never has to move even while the telescope tracks the object. The only change the observer would see is that the object slowly rotates.

Sketch 1 Light from the main mirror (not shown) is reflected by the diagonal mirror at the upper left down the declanation axis to a right-angle prisim located at the intersection of that axis and the polar axis and then along the polar axis into the eyepiece. Light from the spotter scope is reflected into the declanation axis from the opposite direction where it impinges on a second right-angle prisim. The observer switches from the main mirror view to the spotter view as needed by rotating the doubled-up right-angle prisims. While in the spotter scope mode, light from the main mirror is re-directed to a camera mounted on the other end of the polar axis.
