ZWO ASI 1600 Pro Cooled Monochrome CMOS Telescope Camera

The ZWO ASI 1600 CMOS Camera Has set a new standard of Excellence in the world of Astrophotography. Whether you are interested in deep space astrophotography or Lunar/Planetary/solar Imaging, this camera will be able to handle it all. There are not many camera systems that can do what ASI 1600 can do.

As a deep space camera, the ASI 1600 doesn’t hold back any punches. Its cooled versions can reach temperatures 45 degrees Centigrade below the ambient temperature which brings the thermal noise buildup down to a minimum. You can take pictures up to 33 minutes with this camera, but with a read noise of 1.2 to 3.8 electrons (depending on gain settings), exposures that long are rarely necessary. When shooting deep space images at full resolution this camera pairs very well with telescopes with focal lengths between 300 mm to 1,000 mm in focal length, and when it's binned 2x2, telescopes 1,000 mm to 2,000 mm.

As a planetary camera, no other camera system can beat the ASI 1600's versatility. For solar imaging, this camera can record full 16 mp videos at 23 frames per second and capture the entire sun with 1350 mm focal length! If have a need for speed shooting planets like Jupiter and Saturn, the ASI 1600 clocks out at 192.4 frames per second at 320x240 resolution!

When it comes to versatility, look no further than ZWO ASI 1600 Camera.

Camera Sensor

Panasonic MN34230 Sensor

The Panasonic MN34230

At the Heart of the ZWO ASI 1600 is the Panasonic MN34230 CMOS Sensor which is known for its exceptional light gathering efficiency, low read noise, and high resolution. The sensor will record up to 16-megapixel images on a Micro 4/3rds format. The peak quantum efficiently of this CMOS detector is approximately at 60-percent and it has a dynamic range between 9 to 12 stops (depending on gain settings). In other words, this sensor is the same size an 8300 sensor, has twice the megapixels, and is 30-percent more efficient in light gathering!

  • Diagonal 22.2mm
  • 16 Megapixel (4656x3520)
  • Very low read noise: 1.8 electrons at 150db gain & 3.8 electrons the lowest gain setting
  • Electronic shutter: no vibration caused by a with mechanical shutter

DDR Memory Buffer

The ASI 1600 Pro camera includes a 256MB DDR3 memory buffer to help improve data transfer reliability. The use of this memory buffer minimizes amp-glow, which is caused by the slow USB 2.0 transfer speeds.

ZWO ASI 1600 DDR Memory Buffer

DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.

Astrophotography Performance

ASI1600 Pro offers Low read noise, Low dark current, high dynamic range. Its build in 12-bit ADC but provides 12 stops of dynamic range, which is better than KAF8300!

Ask a Question
  • Can I use the filter wheel with this on my Hyperstar on my 11" EdgeHD, or will it block too much of the light path? In that case, I would need to buy threaded filters to screw into the Hyperstar instead.

    You could use the 5 position mini filter wheel without blocking too much (with 31mm unmounted filters) but we do not recommend using the larger 7-8 position wheel with a Hyperstar. Good flat frames will be critical to the best image quality.

  • Is it possible to increase the frame rate by limiting the ROI ? What would be the frame rate for a resolution of ~100x100 pixels ?

    Yes, ROI will increase frame rate, but the speed of your computer and USB 3.0 connection will also have an effect - not to mention the brightness of your subject. The manufacturer does not note frame rate for 100x100, but they do for 320x240. At 12 bits

  • What is the quantum efficiency?

    The Quantum Efficiency is approximately 65% for the ZWO ASI1600MM-C.

  • Is the ADC 16 bit?

    The files are 14 bit in a 16-bit space. Even though the files have a lower bit rate, the camera does have a better dynamic range than a lot of other CCD cameras due the very low read noise.

  • I have a two part question: 1) is is possible to define one or more smaller regions of interest for the read-out? 2) can each individual image be externally triggered?

    Sort of for question 1, unfortunately no for #2. You can select the size of the ROI from a number of different options in the camera acquisition software, but this ROI is always exactly centered on the sensor, so you would need to center your subject bef

  • Is this the latest version (v3)

    All of the current ASI1600 cameras we carry are the latest versions from ZWO.

  • Can you show me the whole configuration in a diagram? I need to mount an Orion vixen refractor. The mounting screws are 6 & 1/4 inches apart

    ADM does not have a diagram for this plate, but the hole pattern can be most clearly seen in this image: Holes and slots are down the centerline and 2" on-center (meaning that the side rows of holes are 1"

  • does this camera utilize Ascom drivers?

    If you are running the camera on a PC, you need both the USB and ASCOM drivers for this camera. on a Mac, you do not need to install ASCOM, but you do need OACapture or Nebulosity software installed.

  • The Zwo site shows two versions, one with a USB2 hub and one with a guider port. Which version is this?

    All of the new ZWO cooled cameras have the 2 port USB hub. To guide, you would need to get ZWO's USB to ST4 adapter (, but the camera hub can power both the ZWO filter wheel and an uncooled ASI120 or simil

  • Is there an OAG compatible with this camera? Also will 1.25" filters cover the chip? or do I need 36mm filters?

    Yes, You can attach an OAG to this camera. There are several things that would need to be accounted for, such as filter wheels and back focus of the telescope that you are using. To configure the best setup for your telescope, I recommend giving us a call

  • what format are the raw images ?

    When you computer is connected to this camera, the software you use will record the raw images as fits files. If you are recording video the video, the file format is AVI.

  • 1. Is the temperature setting adjustable? 2. Can the fan be turned off during exposures? 3. Approximate gain (e-/ADU)?

    Yes, The temperature setting is adjustable. This will be changed in the camera control software that you use. You can unplug the TEC cooler and fan during an exposure and it not will stop the camera from taking the exposure. The image will just be noisi

  • is a tripod included (it's unclear) and if so, what's the model number of the tripod?

    This product is the same mount and tripod that comes with the Nexstar 6 and 8se. Part number for the Nexstar 6/8SE tripod is CE-93593.

  • Is this the newer version with the USB2 hub?

    That wasn't the question. ZWO has two units. One with an ST4 port, the other has two USB 2.0 ports in place of the ST4.

  • Is this the newer version with the USB2 hub?

    The answer above does not answer the question. ZWO has come out with a new version of the ASI1600MM-Cool, replacing the guider port on the back with two USB2 ports, embedding a USB hub into the camera. Is the camera version for sale here the old ver

  • Is this the newer version with the USB2 hub?

    This camera has a USB 3.0 interface and comes with a USB 3.0 cord. You can plug this into a USB 3.0 cable into USB 2.0 interface on your computer and record at a slower frame-rate.

  • will this camera have different resolution settings like other cameras? like 1x1 2x2 or 4x4 binding.

    1x1, 2x2, 3x3, and 4x4 binning are supported by the manufacturer, but this is via software binning after digital conversion, so the download speed/FPS is not improved 2x2 hardware binning is apparently supported but only at 10 bit depth.

  • Can I use the filter wheel I use with the ZWO 174M? Is there an electronic filter wheel for this camera? Or, is there a filter wheel that has 7 filter spaces--or even 9?

    the ATIK FW-2 filter wheel comes with interchangeable carousels , and has a 9 position for 1.25" filters.

  • Can I use the filter wheel I use with the ZWO 174M? Is there an electronic filter wheel for this camera? Or, is there a filter wheel that has 7 filter spaces--or even 9?

    Yes, you can re-use the same filter wheel from your ZWO ASI174 camera. ZWO does not currently have a motorized filter wheel, but we carry 7+ position filter wheels from other manufacturers that are compatible. Please contact us if you have specific ques

  • ASI-1600MC cool = color ASI-1600MM cool = mono is this mono? then title is wrong. 'ASI-1600MC COOLED MONOCHROME'

    Hello, I will forward this to the internet changes department. Thank you for noticing.

  • ??? ???????? ??????? This is cool camera?

    Thanks! At once I haven't noticed.

  • ??? ???????? ??????? This is cool camera?

    Yes, this camera has a thermoelectric cooling system that can run at 40-45C below air temperature.

  • Could this camera also be used for solar imaging in a Ha solar scope? I'm looking to get the most bang for my buck so to speak and want a great DeepSky camera as well.

    Yes, this camera would be great for solar imaging. It can shoot up to 23 frames per second at full resolution. This would be a great way to maximize the detail out solar scope.
