- Excellent OAG for use with any ZWO Camera
- 16.5 mm Thickness
- 8 x 8 mm Prism Size
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 16.5 mm 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 8 x 8 mm, 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.

United StatesZWO OAG
Very good, tiny bit tough to get the focusing down but once it's dialed in, it's perfect.
United StatesNot the quality I expected of ZWO
Crudely implemented design relying on setscrews and sloppily milled parts. This one is going back. Other ZWO products like their cameras are of much higher build quality. Disappointed.
I have 3 of these now
One on each scope setup.
ZWO OAG
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.
