Product Details

  • The 1.25-inch Atmospheric Dispersion Corrector, or ADC with Bubble Level from ZWO, is a brilliant tool for correcting the scattering effect of light rays in the Earth's atmosphere. Experience Fringe-free Observation

    The ADC allows you to view and image bright objects clear of distortions and aberrations. You no longer have to wait for a target to be high enough in the sky for it to be satisfactory to view. With the ADC you can now view objects with perfect clarity no matter their location. ZWO ADC Operation

    The ADC corrects the atmosphere's dispersion effect on planets, stars, and other bright objects by using the chromatic cover of two opposing rotating prisms. Levers on the ADC, when separated by 180 degrees, adjust the two rotating prisms and change the compensation effect from nothing to its apex. The attached bubble level helps line this all up!

    The atmosphere's dispersion effect influences some wavelengths differently than others. Adjusting the ADC's levers provides a simple way to compensate for this.

    Imaging

    Color imaging a planet without an ADC will inevitably result in color fringing and distortion. When the presence of this fringing and distortion is taken away in processing, you wind up with an image with a decreased resolution that cannot be reclaimed. While Mono imaging separates Red, Green, and Blue images, superimposing them helps offset this to some extent. To take advantage of an image's full resolution, a Luminance image should be taken. Use the ZWO ADC, which removes distortions and image shift issues, resulting in an image with more detail. Finally, further processing can produce a complete enhanced final image.

    Customer Support

    Still waiting on clear skies. It looks well made and I hope it does what I need. Thanks for your customer support. I’m enjoying the Celestron 8” SCT Edge I purchased from you. It tracks pretty good, only drifts a little which I can correct for manually. The Star sense camera required a major adjustment to get it close to the target before slewing but it works now. If I wasn’t mechanically inclined, I don’t think I would have got it to track.

    Much needed

    Quick and easy to use with very little earning curve. Most importantly, you need to determine if it is a lefty or a righty.

    Tricky But Effective

    Takes practice and fiddling to understand it, but in the end it's effective.

    ZWO ADC

    With NO, NONE. NOTTA instructions, ZWO products are the worst. Optically, it is great. GO on line and they show you how to use and calibrate it in a software package from another company. there is no instructions on how to use it with their OWN software. The capture program has a feature for the ADC and there is NO mention of it or how to use it. I am very disappointed with this part of the package. They seem to be out growing themselves and will lose customers. Hopefully I can find some time to go online and read/watch some tutorials on how to use it. oh well. it affects the light in the way it was descried. how to get the best out of it will take a little while....

    The ADC came with no instructions at all

    Very disappointed that there were no instructions at all with the device. That is simply unacceptable that one should go find a video on a web article for its correct use. No excuses.

    Don’t know how it works, but it does!

    I view from a heavily light polluted location (backyard, Las Vegas) so I try to mitigate some of that. This accessory works beautifully! My images are sharper and brighter, and the difference in detail is astounding. So easy to use it comes without instructions, but since it arrived it hasn’t been off my telescope.
