ZWO Off Axis Guider

The ZWO Off-Axis Guider is highly effective and efficient. 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 to 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.

Disappointed in quality

First off, of course there are no instructions in the box. You need to go to ZWO’s website to hunt those down. Using all ZWO products in my image train, you’d think that this would actually work easily. It doesn’t. The pillar that holds the mirror looks like it came out of some Chinese garage and was made with hammer and anvil. Extremely low quality and bad fit. Also extremely difficult to adjust focus. If I were to do it over again, I would avoid this at all costs. I’ve gone back to a regular guide scope and much better guiding results.

Not bad but could be much better

The product is not bad. I like how it is compatible with all other zwo products straight out of the box. Focus was easy during the day and would not recommend trying focus for the first time out at night, it was very frustrating. I would give this product 5 stars if the connection between the camera and/or filterwheel was threaded. I do not like having my $2,000+ camera and filterwheel hanging off the back of this thing held in with three screws only.

ZWO Off Axis Guider

Very bad. If not for one fatal flaw it would be fine. The prism pickoff shaft is wobbly no matter how much you tighten it. They need to update the design to that it does not wobble, otherwise this is no good.

ZWO OAG

Very good, tiny bit tough to get the focusing down but once it's dialed in, it's perfect.

Not 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.
