Product Description
ASI1600MC Pro


DDR Memory Buffer
DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.
ASI1600 Pro camera includes a 256MB DDR3 memory buffer to help improve data transfer reliability. Additionally, the use of a memory buffer minimizes amp-glow, which is caused by the slow transfer speeds when the camera is used with a USB 2.0 port.

Astrophotography Performance
ASI1600 Pro offers very good performance for astrophotography. Low read noise, Low dark current, high dynamic range .
ASI1600 build in 12bit ADC but can provide 12.5 stops dynamic range which is even better than KAF8300 due to its super low read noise.
QE Graph
We suppose the QE peak value is more than 60%.

Dark Current
The dark current of ASI1600 from out test result.
here is a 300S dark frame tested with the cooler running at -25 degree.

Reliable Mechanical Structures
There are four screws that seal the sensor chamber. Our camera design has been extensively tested and is very stable.
Even when used in higher humidity environments, ASI1600 Pro will still works fine without dew problems.

USB 3.0 Port & USB2.0 HUB
USB 3.0 Port: Provides 5Gb bandwidth to make it possible for ASI1600 Pro to run at 14.7 fps (12bit, normal mode) or 23 fps (10bit, high speed mode) at full resolution (16Mega).
USB 2.0 HUB: Can connect with various accessories, including a filter wheel, guide camera or electronic focuser, allowing you to manage your cables better. There are two short 0.5m USB2.0 cables included with the ASI1600 Pro. The hub is powered by the external power supply if you connect one.

Cooling System
ASI1600 Pro has 2 stage TEC cooling system to enable very deep cooling (40°C-45°C below ambient). The cooler requires an external power supply, which is not included with the camera. You may order a suitable power supply from here.
We recommend using a 12V/3-5A or more DC adapter for cooler power supply (2.1×5.5, center positive).
Using a battery with 9-15V is also suitable for the cooler power supply.

Just purchased a ZWO ASI1600MC, I own a Skywatcher 80mm PROED Refractor and a Skywatcher 250mm Reflector. Both with Moonlite focuser’s. I am new into astroimaging, I have an NEQ6 Pro mount. I know this CMOS camera has an AR window. I ordered an Explore Scientific CLS 2″ filter with the camera. Will this suffice for IR/UV for the Refractor?
Not terribly familiar with filters…

Sam Wen – :
yes, no need for UV/IR cut any more

And second question: sometimes i would like connect Nikon lens to ASI1600 have you any sutable adapter?
Best regards
Stefan

Sam Wen – :
the easiest way should be screw one 1.25″ IR-CUT to inside of the T2-1.25″ filter adapter
so 1.25″ filter should have no vegnetting for F5 system

Hello,
To connect this camera to my Skywatcher Ed100 Focal Reducer (55mm Backfocus M48 connector), I will need a 37.5mm (M48 to M42) spacer to connect to your M42 connector, which is connected to the camera? (17.5+37.5 = 55) Is this correct?
Sorry, first time I have to deal with back focus..
Thanks, Stefan.

Sam Wen – :
yes, you are correct
there is a 18.5mm M42-M48 adapter come with the camera
so maybe just one 37.5-18.5=19mm T2 spacer is ok too

Hi,
I bought a ASI1600MC-cooled recently and I have not been able to use it with Sequence Generator Pro.
There is a ASI ASCOM option in SGP’s camera selection.
Error message comes up during focus and framing.
I am told by SPG developer that the ASI ASCOM doesn’t work with ZWO cameras at present.
Is there a fix soon?
Regards,
Samuel

Here I am again.
I am planning to buy this camera and also like to buy the new EOS T2 adapter since I already have an EOS adapter for my 2 inch focusser. I now use a Canon 450D in prime focus. Will it be suitable and will I be able to focus?

Hi Sam,
I see a lot of deepsky images when I look for results for this camera. But I guess you are able to capture planets too with this camera as well.
Is this camera really designed for deepsky imaging solely or can I also use it to image planets and the moon. Or is the chip too big for planetary imaging?
Kind regards,
Rene

Sam Wen – :
yes, you can use it for moon or solar imaging
and it support ROI, so planetary imaging is suitable too
this is an all-in-one camera

Hello does this camera need IR filter when using refractors or is it inbuilt?

for the final release version we choose to use build in AR window
so you need an extra 1.25″ IR-CUT filter

Hi Sam Wen, I would like to use ASI 1600MC-Cool but not sure the way to hook it up to Celestron focal reducer as http://www.celestron.com/browse-shop/astronomy/astroimaging-accessories/reducers/reducer-corrector
Does ASI 1600MC-Cool come with the compatible adapter? Or can indicate the adapter I need.
0
0
Sam Wen – :
usually these reducer designed for DSLR whose back focus distance is 55mm
so you need an extender to use it with our camera
we already provide an 18.5mm M42 extender, so you just need another 20 or 19mm extender to reach 55mm distance

Hello Sam,
With the removable M42 extender in place on the ASI1600, the Back Focus Distance switches from 6.5 mm to 17.5 mm. Do you confirm?

sottaku – :
Hi Sam
I think two reasons .
One reason is distance between a sensor and filter is too close.
Another one is a coating of filter .
Then distance between a sensor and filter to be a little more far and try to improve a coating of filter .
I hope your product to be better .
