ZWO ASI 1600 Monochrome CMOS Telescope Camera

The Monochrome ASI-1600 from ZWO is an amazingly powerful and high value deep space imaging camera that can also be used for planetary or lunar imaging. It performs at a high level, and was designed as a dedicated DSO imaging camera, but can still perform in the solar system.

With an incredibly low level of Read Noise at 1.2e-, they operate with minimal interference, producing higher quality images reliably by doing so. It also excels in the FPS field- experiencing a maximum rate of 23 Frames Per Second when operating at full resolution, which is well above average for astronomy Cameras- one of the most models boasts just 1 FPS! And that's not the only two fields in which this camera and it's stellar new sensor have innovated... 

Its resolution is beautiful: running at 16 megapixels, it nearly doubles the resolution of camera's nearly twice its cost. It only runs at twelve bits per frame, but with the drastically lower than average Noise this lack of interference allows you to use much more of your potential dynamic range. This allows higher quality imaging at a lower base bit per frame due to a drastic reduction in noise interference.

This is a CMOS Sensor Camera that is highly affordable without any sacrifice in quality- operating at a whole new level compared to other, similar Cameras. Its range of exposure time is insane- ranging from a mere fraction of a second all the way up to just a few minutes over half an hour. What does that mean, exactly? It means that while yes, it can be used for planetary or lunar imaging, it's also fully capable of being utilized for long exposure deep space photography and imaging, as well as just about anything else you'd care to put it to. The technology at play here is leaps and bounds above what's considered standard in CMOS cameras, and it shows; to get the performance of a similar quality elsewhere, you'd have to double the price of this new camera, and in some areas, this camera might still outperform! Usable for a broad range of imaging purposes with great effectiveness, and extremely affordable, you'll find this a solid investment for a beginning in Astro-Photography!

Ask a Question
  • What extras I need to auto guide long exposures? I have an equatorial mounted apo refractor. The mount has inputs for auto guiding

    You will need either a guide scope or off-axis guider, and a guide camera. We would be happy to assist with setting your system up for guiding. Please give us a call or email us at

  • Does this camera have an ASCOM driver? Specifically, I would want to use the camera with AstroTortilla. Would I be able to do that with this camera?

    Yes, the ZWO ASI-1600MM USB 3.0 Monochrome Astronomy Camera has a ASCOM driver. There is a software page on ZWO’s website with downloads.

  • Can this camera be binned?

    Yes, the ASI 1600 can be binned 2x2, 3x3, and 4x4.

  • What benefits does the cooling provide. Is it worth the additional cost?

    Cooling the camera leads to significantly lower dark current, which allows maximum exposures to go from ~30 seconds to around 5-10 minutes before dark current becomes a significant issue. Subtracting separate dark frames is still recommended for long exp

  • I'd like to be able to assemble LRGB images for post-processing. Does this camera have an option for an integrated multi-position filter wheel? If so, what size are the filters and where can I find more information about that feature? Thank you.

    Good afternoon and thanks for asking. You will want to look at the ZWO filter wheel, ZWO-EFWMINI. Additional information can be found here

  • Does the camera have cooling capabilities? Thank you

    The ZWO ASI1600MM is available in two versions. This one does not have active cooling. Please take a look at ZWO-ASI1600MM-C, which is actively cooled.
