ZWO’s new cooled version of ASI174MM-Cool mono CMOS Imaging Camera allows the sensor to be cooled to 35C to 40C degrees below ambient!
Here is a 60s long exposure dark file of this Camera. The 1″ sensor size and 5.86 pixel size of ASI174 make it suitable for DSO imaging for most scopes.
The high QE and low read noise and super fast speed of ASI174 make it to be a camera capable for all.
Here is a review on Cloudy Night forum.
The QE peak value is about 77%.
Reliable Mechanical Structure
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, ASI174-Cool 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 ASI174-Cool to run at 128 fps (12bit, normal mode) or 164 fps (10bit, high speed mode) at full resolution (2.3Mega).
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 ASI174-Cool. The hub is powered by the external power supply if you connect one.
ASI174MM-Cool has 2 stage TEC cooling system to enable very deep cooling (35°C-40°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.
