Product Details

  • The ZWO ASI224MC Color Astrophotography Camera houses a one-third inch 1.2 megapixel Sony IMX224 imaging sensor with Exmor and NIR technology. This relatively small sensor has a very low read noise of 1.5 e at 60 Gain and 3.1 at zero Gain. There is a high sensitivity in NIR and the possibility for high frame rates, making this CMOS camera an excellent choice for planetary imagers.

    Although this camera is best suited for planetary imaging, it can also be used for imaging deep-sky objects up to a fixed level as it supports a maximum exposure time of up to 1000 seconds.

    Since you won't have to devote time to filters or filter wheel concerns, imaging with the ZWO ASI224MC Color AstrophotographyCamera is a simple procedure. This is one of the best color planetary imaging cameras currently available in this price range.

    Great camera!

    I got this as an upgrade to my ASI120MC-S. Easy to use, fast frame rate, low noise. Just before I sent a message to ask when the backorders might ship, it arrived! Always terrific service from OPT! I recommend getting the IR Cut-off filter to go with it.

    Great Camera

    Took it out the day it arrived and shot the best image of Jupiter I have! Very Happy with this camera.

    Amazing Camera

    This camera is all it claims to be and more. I took it out for the first time in poor seeing conditions: Full Moon near to Saturn, smoke in the skies from the wildfires and Class 7 Bortles. They pics still blew me away. I can't wait until I get some clear skies and learn how to use it better.

    Didn’t work correctly for me

    I get grid / checker pattern that is difficult to correct. I have gone to great lengths to fix the issue with no improvement or change.

    Generally a good camera!

    This camera is pretty good. I use it with my Celestron 8SE. I’ve had some issues getting the focus to work, but I think that has more to do with my experience level than the camera itself. I will say, that the ASi interface for the Mac isn’t great. It “works,” but there’s very little explanation of how to use it or what each function does. I had to purchase another program to run this camera, and that works better (AstroImager). PC folks probably won’t have these issues, though you will have to install drivers. For the price, I’d say this is worth it.
