WHAT'S NEW: DDR Memory Buffer
The 256MB DDR memory buffer is the main difference between the previous ASI1600 “Cool” and the latest “Pro” cameras.
Whilst the original ASI1600MM-COOL camera is a perfectly capable USB3.0 camera, those who wish to use it via a USB2.0 port, can now do it with better success as the addition of the 256MB DDR3 memory buffer means more stable data transfer even at the lower speed of the USB2.0 port, plus reduced amp-glow for the same reason.
WHAT'S NEW: Further Improved Mechanical Structure
The ASI1600-PRO uses 4 screws to seal the chamber. This structure has been fully tested and is very stable and reliable.
Even under high humidity eviroment, ASI1600-PRO still works fine and won’t have dew problems.
WHO IS IT FOR?
The ZWO ASI1600MC PRO 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. It is also a much more affordable alternative to converting a dSLR.
This version also comes with built-in active cooling that helps to reduce electronic noise to the minimum.
You can even use it for guiding, although we understand that it is somewhat a waste of a talent to use it for guiding, but there might be special circumstances or setups when you would want to use it for guiding, so the opportunity is given.
There are four versions with the same large 4/3" sensor (21.9mm diagonal):
Colour or monochrome and cooled or uncooled.
Now you will have to decide whether you want a simple solution and go for a one shot COLOUR CAMERA or would like to get more data out your camera and go for the MONOCHROME version. If you would mainly use it as a deep sky imager camera, we'd also recommend to go for the COOLED version, but if you cannot afford or you'd be mainly using it as a very high resolution planetary imager, then go for the UNCOOLED version.
With the ZWO ASI1600MC you won't have to spend lots of time to get beautiful images, however, if you want to get the best results from this range of cameras and you have plenty of time to spare, why not to try L-RGB or narrow band photography with the monochrome version of this camera, the ZWO ASI1600MM or ZWO ASI1600MM-COOL. (If you go for the monochrome version, you'll also need a filter wheel and a set of L-RGB filters or H-alpha and OIII filters, and maybe even H-beta and SII filters as well for narrow band photography...)
Please note that the sensor diagonal size is very close to the internal clear aperture of a 1.25" filter, therefore with extremely fast telescopes (small f-ratio) there might be vignetting. The limiting f-ratio will depend on how you will use it (i.e. with filters or without and what size). Some users might use it with CLS CCD or L-PRO filter to cut out light pollution, others might even use a H-alpha filter for certain objects. We use one of these in our observatory with a Hyperstar on our C11 Edge HD telescope as the round shape and size of this camera is perfectly fits in front of the Hyperstar without covering more than the secondary mirror holder would do. Plus we opted for the colour version as a large filter wheel cannot be used in that position and although we use it with a filter drawer that would allow to use LRGB and HSO filter sets, it would be too much trouble to change the filters (involves climbing on a ladder), so we use the colour version with a 2" Optlong L-PRO filter and sometimes with an 2" Astronomik 3nm H-alpha filter for some cool deep sky objects...In the above setup we don't experience any vignetting.
Images are for demonstration only. Canon EOS lens adapter is not included, but available separately.
Features of the NEW ZWO ASI1600MC-PRO COOLED Camera
Recommended for Deep Sky Imaging as well as the Sun, Moon and planets at very high resolution (the monochrome version is better for the Sun)
(To image the Sun you'll have to use a proper front solar filter or Herschel wedge depending on your telescope. Please contact us if not sure!)
