Ocular turret telescope system

An ocular turret system adapted for connection to a main viewing barrel of an optical instrument;

• the system comprising:
• (a) a first barrel attachment cylinder adapted for attachment to the viewing end of said main viewing barrel;
• (b) a second cylinder mounted within said barrel attachment cylinder with the center of said second cylinder adapted to being positioned to align with the longitudinal optical axis of said main viewing barrel;
• (c) an eyepiece cylinder extension aligned at a first open end with said second cylinder;
• (d) said eyepiece cylinder extension connecting at a second open end to one end of an eyepiece mounting cylinder that is concentric with said eyepiece cylinder extension, said eyepiece mounting cylinder being open at an opposite end and having a cut-out opening on the periphery thereof;
• (e) a selectable eyepiece housing comprising a generally circular ring having a plurality of selectable eyepiece barrels mounted about the periphery thereof;
• each of said barrels include respective apertures connecting with the interior of said ring, said ring being placed over said eyepiece mounting cylinder and being rotatable relative thereto about a common axis to selectably bring said eyepiece barrels into registration with said cut-out opening in said eyepiece mounting cylinder.

An ocular turret system adapted for connection to a main viewing barrel of an optical instrument;

• the system comprising:
• (a) a first barrel attachment cylinder adapted for attachment to the viewing end of said main viewing barrel;
• (b) a second cylinder mounted within said barrel attachment cylinder, the center of said second cylinder adapted to align with the longitudinal optical axis of said main viewing barrel;
• (c) a transverse cylindrical housing attached to a first end of said second cylinder and connected to said second cylinder through a first circular opening in the sidewall of said transverse cylindrical housing, said transverse cylindrical housing having a second circular opening in the sidewall opposite to and aligned with said first circular opening;
• and
• (d) a filter and magnification selection turret removably mounted within said transverse cylindrical hosing and rotatable relative thereto about a common axis, said turret comprising a plurality of apertures about the periphery thereof, each of said apertures being associated with an opposing one of said apertures to form viewing pairs with at least a first of the apertures receiving a first lens and a second of said apertures receiving a second lens different than said first lens;
• said turret being positioned within said transverse cylindrical housing such that, when said turret is rotated, said pairs of apertures are sequentially brought into registration with said first and second circular openings in said transverse cylindrical housing whereby said pairs of apertures are individually selectable by rotting said turret;
• (e) an eyepiece cylinder extension optically connected at one end thereof to said second circular opening in said transverse cylindrical housing;
• (f) said eyepiece cylindrical extension optically connected connecting at a second end thereof to one end of an eyepiece mounting cylinder that is concentric with said eyepiece cylinder extension, said eyepiece mounting cylinder being open at a second end thereof and having a cut-out opening on the periphery thereof;
• and
• (g) a selectable eyepiece housing comprising a generally circular ring about the periphery of which are mounted a plurality of selectable eyepiece barrels;
• each of said barrels include a respective viewing apertures optically connecting with the interior of said ring, said ring being placed over said eyepiece mounting cylinder and being rotatable relative thereto about a common axis to selectably bring said eyepiece barrels into registration with said cut-out opening in said eyepiece mounting cylinder.

In a telescope optical viewing apparatus having a main viewing barrel, the improvement comprising:

• (a) a transverse cylindrical housing optically connected at a first end thereof to said main viewing barrel through a first circular opening in the sidewall of said transverse cylindrical housing;
• said transverse cylindrical housing having a second circular opening in the sidewall opposite to and optically aligned with said first circular opening;
• and
• (b) a selection turret removably mounted within said transverse cylindrical housing and rotatable relative thereto about a common axis, said turret having a plurality of radially extending apertures about the periphery thereof with at least one of said apertures receiving a lens therein;
• each of said apertures being associated with an opposing one of said apertures to form viewing pairs;
• said turret being positioned within said transverse cylindrical housing such that, when said turret is rotated, said pairs of apertures are sequentially brought into optical registration with said first and second circular openings in said transverse cylindrical housing whereby said pairs of apertures are individually selectable by rotating said turret.
