ZWO ASI178MC-Cool Color 6.4 Megapixel CMOS Color Astronomy Camera with USB 3.0 and ST4 Guide Port.

I have used this camera, mostly for Guiding and Polar Alignment routines, and for some planetary imaging, and it performs well. I will admit, there is a bit of a learning curve as there always is in the very challenging hobby of astrophotography. Again, like anything else new, after a few sessions I found it very easy to use. (Hint - as with any CMOS or CCD camera, pay close attention to the focus distances in the specs and use the appropriate adapters for the instrument you’re using it on).

I have included photos of the camera connected to my laptop, showing Windows 10 Device Manager recognizing it as an Imaging Device. I also have numerous photos of the SharpCap Software running with the camera attached and operational.

As you can see in the photos, the ambient temperature of the camera without the TEC cooler activated was 25.5 degrees Celsius. Within 5 minutes of activating the TEC, the chip temperature was -20 degrees Celsius, a drop of 45.5 degrees Celsius (113.9 degrees F) below ambient. ZWO conservatively claims up to a 40 degree C drop, but my observations have been 45 degrees C and more, even without the cooler power at 100%.

A word on power supplies for this camera:

ZWO does NOT include a power supply with their cameras, this one anyway. The power requirements for this camera are (directly from the ZWO site):

“We recommend using a 12V/3-5A or more DC adapter for cooler power supply (2.1×5.5, center positive).”

Strangely enough, the specs call for 12v at 2amp max, which is what I used.

You can purchase one directly from ZWO or here on eBay.

This camera and cables are in excellent used condition with extremely minor surface scratches on the camera nose from mounting and body.
