This is an exciting moment as with this NEW ZWO ASI1600MM-C camera, ZWO made its debut into the DSO imager camera market.

The ZWO ASI1600MM COOLED camera is an excellent choice for imaging deep sky objects, however it can do much more than that. With a max framerate of 23 FPS this camera can also be used as an extremely high resolution planetary imager. If you cannot decide if your thing is deep sky or planetary imaging, go for this camera.

This version has built-in active cooling that helps to reduce electronic noise to the minimum.

In order to image in colour with this monochrome camera, a filterwheel and L-RGB Filters will be required. You can also image in Narrowband with relevant narrowband filters.

Please note that the sensor diagonal size is very close to the internal clear aperture of a 1.25" filter, therefore with fast telescopes (small f-ratio) there might be vignetting.

The limiting focal ratio with the ZWO manual filter wheel depends on the thickness of the filter glass that you use, and its clear aperture. The latter is usually 24mm for 1.25" filters.

Filter glass thickness:

  • 2mm  Limiting focal ratio: f/8.5 - lower will give vignetting
  • 3mm  Limiting focal ratio: f/9 - lower will give vignetting
  • 4mm  Limiting focal ratio: f/9.5 - lower will give vignetting

Above are approximate figures as the filter's actual position within its housing will also influence the calculation.

As you can see from the above, a combination of this camera with a ZWO 1.25" or similar 1.25"filter wheel would work well with Schmidt-Cassegrain or slower telescopes, but for fast refractors and reflectors, F6 and lower, a filter wheel that can accept 31mm filters would be better suited as that would allow much lower focal ratio limits: f/2.8, f/3 and f/3.2 respectively.

On the included CD you'll find drivers and two software applications: Firecapture and SharpCap. These are both freeware and the latest versions can be downloaded from the developers' websites.
If you have any problem with installing any of the software from the CD, please download them from here:
Firecapture Beta Downloads
SharpCap Downloads


We'd recommend to always use the beta version of Firecapture, but reverse to the latest stable version if you experience problems.


For full specification, driver installation tutorial (youtube video), basic usage information and recommended third party software please visit the manufacturer's website: ZWOptical

There is also a Yahoo Group where you can find lots of information about how other members use the ZWO cameras: Yahoo Group ZWO ASI Cameras
