It allows you to use the guiding camera at the telescope's prime focus, thereby avoiding heavy guide scopes and achieving much more precise autoguiding!\u003c\/p\u003e\n\n\u003cp\u003eThe off-axis guider uses an internal prism to intercept a small portion of the light arriving from the telescope and reflects it onto a guide camera. Since the guide camera and imaging camera use the same focal length as the main telescope, the guiding will be more precise and will not suffer from the flexure typical of an external guide scope.\u003cbr style=\"letter-spacing: 0.23px;
