The Goal

(Or something like this)

Took a break from polishing to think about the end goal of the project, a Bino-Scope. After teaching myself Auto-Cad, Here’s what I hope the end result may look like.

The two biggest problems of a bino-scope is getting two telescope systems to point at the same target AND adjust the distance between the Eyepieces so they line up with your eyeballs. Not an easy task, but I hope I have an answer.

Each Telescope assembly will consist of a tube and string OTA (Optical Telescope Assembly) that has a triangular base holding the mirror, and a round secondary cage at the top. The Secondary cage (shown in red) will hold the Secondary and tertiary mirrors, the focuser and the eyepiece. The secondary cage will rotate around a stationary center ring (shown in green) which will allow for inter-ocular adjustments.

The triangular base of each OTA will be secured to a common Back board. Out at the corners of the triangle will be a special bolt. The bolt is called a Leveling bolt, and consists of a threaded rod with a ball and socket joint attached to a round steel pad. My hope is to secure the pad to the common backboard with the treaded rod going thru the triangular base and protruding inside the hollow truss tube. Down the center of each truss tube will be a steel rod, attached to a handle up by the secondary cage (see below images) The handles will turn the threaded portion of the leveling bolt, there by adjusting the colmnation between the two OTA assemblies.

The common back board will be attached to modified Dobsonian Alt/Az base, that will hopefully be motorized someday after completion.

In the mean time, I have compiled a small video of the proto type scope, its an animated GIF file (220Kb) Goal.gif

Time will tell if this will work or not, We shall hopefully know soon!

Take Care,
