ZWO OAG Off-Axis Guider

The ZWO Off Axis Guider allows you to connect a guide camera to your imaging camera, and comes with several different adapters to make that happen. That means you can guide and capture images of celestial objects simultaneously through one telescope. No guide scope required! The ZWO OAG has a large 8mm x 8mm prism and is lightweight yet tough. It is machined out of aluminum and black anodized for long wear and beauty. The main portion of the OAG is 16.5mm thick, and, along with the required machined adapters, will provide a solid connection at all points.     The ZWO OAG off axis guider is compatible with all ZWO ASI cameras. To make sure your system comes to focus, you will need to calculate the required distance for your imaging train, and then use the proper extender.

Next, insert the prism back into the OAG body, and then mount your guide ca
