Product Description
The ZWO ADC is a great tool for your imaging toolbox. It allows you to negate the effects of distortion and aberrations on bright objects. You can even get great views when the objects are low on the horizon.
The ADC uses two prisms that rotate allowing you to adjust the amount of effect needed for your particular imaging session. The body of the ADC is female t-threaded. It also comes with a standard 1.25" black barrel for ease of use with an eyepiece holder or diagonal. There is a 1.25" eyepiece adapter with a brass compression ring as well.

Arrived in perfect condition (thanks Ken!). Oddly no instructions in the box though I guess ZWO guesses you'll go online for that. I did. Anyway, solid, smooth, robust. With a lot of the planets still low in the ecliptic for New Englanders, often 25° elevation, it should prove itself well on Jupiter, Saturn, the moon, etc. . Thanks again Ken! (Posted on 9/15/2022)

Re-Post to update my earlier ADC review and warranty claim situation. After weeks of arguing with ZWO about the defect in my ADC unit and their assembly process that has resulted in several end-users receiving units that were either impaired in their performance or completely unusable, ZWO has finally agreed to replace mine free of charge.
I commend ZWO for taking a more serious look at my claim and realizing that there was something going on in their assembly process that needed to be re-worked. It's a shame it took this level of complaining and going public with it to get results on something that was so very obvious. But ZWO did eventually do the right thing and stood behind their product. I think that is the most important thing to remember about this is they did do the right thing when it came down to it.
For USA customers, just be sure you always buy from a premium stateside dealer like Astronomics so that you can have more recourse from the vendor backing you up as well as USA consumer protection laws if you get a defective product built by an overseas manufacturer.
Thanks,

ZWO is mis-assembling these ADC units with the prisms bonded in permanently out of rotational alignment and sending them out defective to consumers. Several reports are out there now on astronomy blogs about this. Some of them are so badly assembled they are completely unusable without making major modifications to the prism housings inside the unit.
What is worse is that ZWO is failing to meet their warranty responsibilities and not standing by their product. It's basically just tough luck on the consumer if they get a bad one and try to return it to ZWO directly themselves.
If you get one of these ZWO units, be sure to only get one from a reputable dealer with a strong customer service ethic like Astronomics, and also be sure to test the unit while you still have a return window available to work with the dealer. Or better yet find one from a different manufacturer and go with that one instead of ZWO. Just my opinion from personal experience with ZWO and I have the tech support transcripts and defective product on-hand to prove it.
Thanks,
