OAG-L has a large prism size of 12*12mm, far bigger than M68 OAG. The bigger clear aperture brings wider field of view in guiding. It is easy to use, and suitable for users who are interested in long focal length photography.

To take the most advantage of it, we recommend you to match it with large format guiding cameras.

3. The effective light-passing aperture is 11.7mm*8.3mm.

4. Can be used to connect the main camera and guide camera simultaneously. No guide telescope required.
