OFF-AXIS GUIDER (OAG) low-profile 13 mm optical length, 2 ", with T2 thread (2x)

Off-Axis Guider (OAG, system for off-axis tracking) is a device that allows you to guidate (track an object) using the same optical tube through which the image is taken. A part of the light beam lying peripherally to the optical axis is directed to the guiding camera. Offered OAG is characterized by a low profile (13 mm), which is also great for short telescopes, both refractors and Newtons.

Technical parameters

• base length: 13 mm
