Designed to allow simultaneous imaging and autoguiding through a single telescope, this compact accessory eliminates the need for a separate guide scope while helping reduce guiding errors caused by differential flexure.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWith an exceptionally thin 10.5 mm body, the Orion TOAG is particularly well suited for Newtonian reflectors and other imaging systems where available backfocus is limited.

This allows the guiding system to monitor tracking errors through the same optical system used by the primary imaging camera, helping maintain accurate tracking during long-exposure astrophotography.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003ch3\u003e\u003cspan\u003eKey
