Multi-purpose optical corrector system

A method of using a modular optical system which is independent of a telescope, the independent modular optical system being of the type that repositions the focal plane of a focused image produced by the telescope from a point where it would conventionally be viewed by a user of the telescope, to a point where a focused image is viewed by a user of a remote viewing device used in combination with the telescope, the remote viewing device being of the type that has an image input portion for receiving the focused image and an image output portion at which the user can view the focused image, and a significant amount of lightpath therebetween, the independent modular optical system including a first housing having first and second opposed ends and supporting therebetween a telenegative-type lens, and a second housing having first and second opposed ends and supporting therebetween a positive-type lens, and said independent modular optical system not including the remote viewing device, comprising the following steps,

• coupling the first end of the first housing to a telescope in a manner so that the telenegative lens intercepts the image plane provided by the telescope,
• coupling the first end of the second housing to the image input portion of the remote viewing device, and
• coupling the second end of the first housing and the second end of the second housing to each other in a manner so that the distance between the telenegative lens in the first housing and the positive-type lens in the second housing results in the intercepted image plane being repositioned from the viewing position where it would conventionally be viewed by a user of the telescope to a viewing position substantially increased therefrom and is at the image output portion of the remote viewing device.
