Abstract:
1. An improvement to an optical telescope that includes a first optical path and a second optical path, said first optical path including a first wavelength of light and said second optical path including a second wavelength of light and wherein said second wavelength is different than said first wavelength, and wherein at least one optical group is adapted to be inserted into either said first optical path or into said second optical path and removed therefrom, wherein the improvement comprises: maintaining said first wavelength of light in said first optical path and maintaining said second wavelength of light in said second optical path when said at least one optical group is inserted into either said first optical path or into said second optical path and maintaining said first wavelength of light in said first optical path and maintaining said second wavelength of light in said second optical path when said at least one optical group is removed from either said first optical path or from said second optical path, and wherein said first optical path includes visible light and wherein a secondary mirror is inserted into said first optical path or removed therefrom as said at least one optical group, and wherein when said secondary mirror is inserted in said first optical path, said visible light is reflected off of said secondary mirror as part of said first optical path, and wherein when said secondary mirror is removed from said first optical path said visible light is not reflected off of said secondary mirror as part of said first optical path; and including a primary mirror and an upright member, wherein said upright member includes a bottom first end and an upper second end, and wherein said bottom first end of said upright member is attached to a base assembly at a first location and at a second location and wherein said first location is disposed inside an aperture that is provided in said primary mirror and wherein said second location is disposed beyond a circumference of said primary mirror, and including a turret assembly and wherein said turret assembly is pivotally attached to said upper second end of said upright member, and wherein said secondary mirror is attached to said turret assembly and wherein said turret assembly urges said secondary mirror into or out of said first optical path.
