ZWO ASI1600MM Pro 31mm Cooled CMOS Camera Kit

 Versatile | Compact | Exceptional Image Quality

The ZWO ASI1600MM Pro is a Micro Four Thirds camera packed with features that help you produce world-class images.

ASI1600MM Pro Cooled Camera Features

  • Exceptional noise reduction technology and video capabilities.
  • The 1600MM Pro is ideal for photographing: Nebulae, galaxies, planets, solar images, lunar images, and more.
  • USB 3.0 Port allows your camera to run at 14.7 fps at base through its 5 GB bandwidth.
  • USB 2.0 Hub attach various accessories for better cable management.
  • Two-stage cooling system for long exposure shots. 

The ASI1600MM Pro Cooled Camera Kit Experience


The ZWO ASI1600MM has a built-in 12-bit ADC but can provide over 12 stops of dynamic range! Which means it can capture a wider tonal range a KAF-8300 sensor. The Camera inherently has a much lower read noise, at a 0 gain setting and will further decrease the higher the gain.

It also includes an upgraded PCB board with a 256MB DDR3 memory buffer. Slow data transmission can cause amp-glow around your image, so the DDR memory buffer takes care of that for you. 


Most ZWO cooled cameras have a short back focus, making them very adaptable to almost any telescope system. The ZWO ASI1600MM has a back focus of 6.5 mm! Check the ZWO Pro Back Focus Chart for the best configurations.


The ZWO EFW8 can hold up to eight 1.25-inch mounted or 31 mm unmounted filters. The 31 mm filters are held in place with included set screws and washers.

The EFW8 body is CNC machined from aircraft-grade aluminum and is black anodized. It is sturdy and reliable, yet weighs just 14 ounces and is 20 mm thick! Inside, an NPM stepper motor is used to rotate the carousel in any direction. The EFW8 is powered via USB and includes a cable that can be plugged into the USB2.0 hub of ZWO cooled cameras.


Switch between each filter to gather colorful variations of light resulting in different vivid images! Every ZWO ASI1600MM Pro Kit comes with a set of LRB filters and a complete set of 7-nanometer narrowband filters (Ha, Sii and Oiii). Finely polished down to an optical accuracy of one-fourth wave, the filters provide zero apparent optical distortion from the filters. To avoid vignetting, use this kit with optical systems no faster than f/8.

Great kit once you get the filters installed.

I recently made the switch from a cooled one-shot-color camera to mono and this is the kit I went with. I've only gotten to use it a few times, but I am blown away by how clean the data is, even with small integration times. 50 minutes of HA on NGC 7000 totally smokes hours of data from my OSC! The only thing I really did not care for was installing the filters in the filter wheel. It's hard to tell which way the filters are suppose to be placed, and getting the screws into the holes was needlessly difficult... But even still, the quality of the images you can get from this kit is awesome, and I'm very happy with my purchase.

Excellent Camera!

I’ve had my eye on this camera with the filter package for about a year or more. I finally made the switch from a DSLR to a dedicated astronomy camera. The directions it comes with are a little inadequate (mainly in the area of filter installation) however there is plenty information online. If your already using software to control your camera, using it is pretty intuitive. I did switch from Backyard EOS to Astrophotography Tool (APT). but the concept is the same. I created my first LRGB image of M51 on first light and it’s a really impressive camera. Did 10 minute luminance subs at 139 gain (the unity gain) at -25 and the SNR was outstanding compared to my DSLR. Bottom line: camera is easy to use and does well what it’s intended for.

Upgrading from DSLR to CMOS - Couldn't be happier

The cloudy weather curse struck just as I got this camera in, but have been enjoying it so far! Switching from a DSLR wasn't much effort (the 31mm filters being the hardest part of installing given its hard to tell which direction is the correct orientation). Mechanically the package works beautifully together and I'm getting crystal clear images (only managed some lunar luminance so far due to weather). With the short exposures I've done on the moon alone, I'm definitely noticing an improvement from the DSLR even so far, so very much looking forward to imaging LRGB on some DSO - maybe even trying out the SHO filters sooner than later!
