ASI294 - Backlit MONO sensor even more performing!
The new ZWO ASI294MM PRO camera is the first camera in the world to use the Sony IMX294 monochrome sensor.
This new Sony sensor is the first sensor for monochrome astronomical cameras to use the 4/3" format and to have the pixel output required to support the 4K format at 120 fps (ADC 10bit output mode).
Furthermore, the use of a large pixel achieves SNR1s of 0.14 lx*, very close to the value of the ASI224 (0.13 lx*).
Unlike its younger sister ASI1600, this new camera has a backlit sensor (BSI) that allows it to reach QE up to 75%.
12V 5A power supply for Peltier cooling as a gift!

Outstanding Low Illumination Performance SNR1s: 0.14lx
This result is achieved using a large optical system and expanding the area per pixel to 4.63 microns; making the IMX294 monochrome sensor ideal for astronomical applications where high performance is required even in low light.

SONY 11.7MP sensor with 23.2mm diagonal
The SONY IMX294 sensor has a diagonal of 23.2mm and pixels from 4.63x4.63 microns, the 4/3 "format is the same as the ASI1600 cameras with Panasonic sensor but much more performing, with 11.7MP and a resolution of 4144x2822.
With this sensor it is possible to photograph an entire cluster of galaxies and show the details of each one at the same time!
The chamber also features TEC Cooling with a thermal delta of the ambient temperature down to -40°.

Technical features:

  • Two-stage regulation with a temperature delta of 40 ° with respect to the environment
  • Electronic shutter: no vibration
  • Extremely low reading noise: 2.3e @ 24db gain 3.3e @lowest gain
  • 14bit ADC: provide real 14bit Dynamic range
  • USB 3.0: Super high frame download speed, avoid data loss during download
  • USB 2.0 HUB: Double USB 2.0 port useful for connecting the driving camera
  • Window with AR coated
  • Compatible with Windows-Mac-Linux

256MB DDR3 internal memory to not lose any frames!
Thanks to the brand new 256MB DDR3 internal memory you won't lose any information even through the USB 2.0 outputs!

The new ASI294 is able to reach a Full Well Capacity of 66000e, it is 3 times higher than that of the ASI1600!
Even bright stars do not become saturated with long exposures!

This camera can achieve higher SNR (signal to noise ratio) with just one exposure.

This chamber, like all monochromatic cameras, requires filters and a filter wheel
