ZWO Off Axis Guider
This slim and lightweight piece of hardware presents a beautiful profile to begin with- but it's far more than just a pretty hunk of 16.5mm thick metal. It is a highly effective and efficient Off Axis Guider, a great choice for those looking to avoid weighing down their setup too much with the additional component. The Prism is a relatively large 8X8mm, and due to how the OAG is designed you may mount it to your telescope, and then mount both your main imaging camera and your guide camera to this same OAG. This OAG is compatible with all ZWO ASI cameras, and a variety of telescope threading options can be adapted for or attached into with great flexibility. Once connected, you will find the bonds between this OAG and your telescope to be stiff and exceptionally stable, as firm and lasting as could be desired. This generally can also be applied to the connections to your cameras.

I have 3 of these now
One on each scope setup.
OPT has been very good in fulfilling and shipping this order. The product itself is well made. To a person new at Off Axis Guiding, it's a bit complicated and instructions must be carefully read. One needs a good supply of adapters to assemble an OAG correctly! I have no complaints.
Good price, but flawed design.
Works OK, but threads into ZWO filter wheel leaving the pick-off prism at the wrong angle (about 45 degrees off alignment with the imager). This makes a big shadow over the image. It's possible with shims to align the prism properly, but would have been much better if the OAG and filter wheel were designed to thread together properly. Also, the opening from the prism to the guide camera obstructs about ⅓ of the light path. This can be corrected with guider flats, but it the aperture and prism are clearly mismatched.

Nice OAG. Easy to use.
Zwo off axis guider
Easy to set up in the optical train. Several adapters are included that will fit most systems. Good price - good product - good support from the folks at OPT.
Great product, high quality and super thin which was a big help with my setup. I use it with my SBIG ST-I guide scope. It came with all the adapters I needed. I wish I had started using an OAG a long time ago. Much better than using a guide scope, I saw a big improvement in guiding immediately.
