Astrophotography Performance

The ASI183 cameras has a very large full well capacity(15000e for such small pixel size, 1.6e read noise @ 30DB, and 12stops dynamic range @ Gain=0. The ASI183 cameras also utilise firmware features to minimise amplifier glow for maximum performance in astrophotography.

High Speed

Fast FPS can be used in solar and lunar imaging, as well as for live viewing/EAA.The high speed readout may also be used for real-time focusing, true lucky imaging of double stars and other small objects, planetary imaging of the major planets in the solar system, and much more.

10Bit ADC

  • 5496×3672    19fps
  • 3840×2160    41.04fps
  • 1920×1080    80.10fps
  • 1280×720      117.30fps

12bit ADC    

  • 5496×3672    19fps
  • 3840×2160    36.12fps
  • 1920×1080    70.48fps
  • 1280×720      103.23fps

High QE

Sony’s back-illuminated Exmor R technology, gives it excellent Deep Sky performance. ASI183 QE peak reaches a remarkable 84%. In the Ha channel, QE is still over 60%.

Having high QE means more of the light that enters your telescope and reaches the sensor is actually used. With 84% peak Q.E. and no less than ~50% within the visible spectrum, the ASI183 will utilise a high percentage of the light that reaches it, improving your signal quality.

Dark Current

The dark current of the ASI183 is extremely low, based on our test results.

USB Ports

USB 3.0 Port: Provide 5Gb bandwidth to make it possible for ASI183 to run at 19 fps (12bit, normal mode) or 19 fps (10bit, high speed mode)  at full resolution(20.18Mega).

ST4 Port: can be used connect with auto guide port of mount, for guiding.

Ok not used it loads yet, but enough to know it is performing as well as expected and providing the results I wanted.

I use it for eeva and unguided imaging and it is well up to the task given.
