IMX385 Sensor
8.35mm diagonal, approximately 2.12 megapixels.
High sensitivity with 3.75μm pixels.
Sony developed the IMX385LQR CMOS image sensor for industrial applications but it's sensitivity is nearly twice that of the sensor it replaces (IMX185LQJ) so is an excellent choice for astrophotography.
The IMX385LQR sensor's large 3.75μm pixels have a sensitivity of 2350 mV (the highest among Sony image sensors for industrial applications) and SNR1s of 0.13 lx (the highest among Sony Full HD-compatible image sensors for industrial applications). This is achieved via an internal programmable gain amplifier and high conversion gain pixels. It also combines HDR (High Dynamic Range) technology with technology that improves sensitivity in the near-infrared light region for truly remarkable performance!
All ZWO cameras include a 2-year warranty.

ASI385MC-Cool has extremely low dark current, click here to see a dark frame from ASI385 camera (HDR settings, 60s, -10°C).
USB Ports
USB 3.0 Port: Provide 5Gb bandwidth to make it possible for ASI385 to run at 67 fps (12bit, normal mode) or 120 fps (10bit, high speed mode) at full resolution (2.13Meg).
Power Requirements
ZWO recommend 12V at 3A~5A or more DC adapter for cooler power supply (2.1*5.5, center positive).
Battery from 9-15V is also suitable for cooling power supply.
USB 2.0 HUB: Can connect with various accessories, such as filter wheel, guide camera and electronic focuser, for convenient cable management using it's inbuilt USB2.0 hub. The USB Hub draws power from an external power supply if you have one connected. Two short 0.5m USB2.0 cables are included.

I would certainly recommend FLO for all your astro needs, fast delivery and keen prices.
High rate of frames and valid for DSO Thursday, 26 April 2018 | Mario
I recently acquired one of this cameras to replace my old AS120MM as a guide camera, and also for the incoming planetary season.
Shooting at the Moon at full resolution I got almost a 170fps rate, just amazing. I also use this camera as a lucky DSO imaging, and the bigger sensor allows you to use it as a globular cluster and individual galaxies smasher. Waiting forward to use it with Jupiter soon.
