The Sony IMX094

  • Full Frame Diagonal 43.3mm
  • 36 Megapixel (7376x4928)
  • Very low read noise: 2.1 electrons at 150db gain & 3.1 electrons the lowest gain setting
  • 14Bit ADC: provide a real 14bit Dynamic range
  • Electronic shutter: no vibration caused by a with mechanical shutter

DDR Memory Buffer

The ASI094 Pro camera includes a 256MB DDR3 memory buffer to help improve data transfer reliability. The use of this memory buffer minimizes amp-glow, which is caused by the slow USB 2.0 transfer speeds.

ZWO ASI 094 DDR Memory Buffer

DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.

Astrophotography Performance

ASI094 Pro offers low read noise, high dynamic range, a QE peak around 56% and much more.

USB Port &Hub

USB 3.0 Port: Can Handle up to  5Gb bandwidth which allows ASI 094 Pro to record 5 fps at full resolution(36Megapixels).

USB 2.0 HUB: an 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 ASI 094 Pro. The hub is powered by the external power supply if you connect one.Tilt-Adapter


The Camera includes unique tilt adapter. This is extremely useful when you need to collimate the sensor plane on fast optical systems

anti-dew and cooling system

ASI094 MC Pro has a two-stage TEC cooling system that allows deep cooling (35°C-40°C below ambient). You will need an external power supply to power the cooler. An AC-DC power adapter is not included in this package, however, you can order one from here.

We recommend using the ZWO external power supply. Using a 9-15V battery is also suitable to power the cooler and anti-dew heater.
