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 offers very good performance for astrophotography. Low read noise, high dynamic range, QE peak >80%, AR protective window and much more.

Dark Currents

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. 

Cooling System

ASI385MC-Cool has 2 stage TEC cooling system to enable very deep cooling (40°C-45°C below ambient).

You need an external power supply to power the cooler. An AC-DC power adapter is not included in this package.
