The ASI183MC is ZWO's most sensitive camera to date which is made possible due to a back iluminated sensor. It comes with a IMX183CLK-J/CQJ-J sensor. It has a diagonal of 15.86mm and an approximately 20.48M-Effective Pixel Monochrome/Color CMOS Image Sensor.
High Speed and High Picture Quality Rolling Shutter-Type Back-Illuminated CMOS Image Sensors:
The ASI183 uses Sony's IMX183CLK-J (monochrome) and IMX183CQJ-J (color) sensors which has a very high sensitivity back-illuminated structure with high resolution 2.4 μm square unit pixel. The optical size is 1 inch.
DDR Memory Buffer:
The ASI183 Pro camera includes a 256MB DDR3 memory buffer to help improve data transfer reliability. Additionally, the use of a memory buffer minimizes amp-glow (caused by the slow transfer speeds when the camera is used with a USB 2.0 port) in order to capture clearer viewings!
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 utilize firmware features to minimize amp-glow for maximum performance in astrophotography.
The ASI294MC Pro has the same sturdy mechanics and elegant design as the ASI1600 Pro. ZWO's recognisible sleek hot-rod red housing not only protects the sensor chamber, but works incredibly well in wet and humid environments without dew problems.
The camera's fast FPS is ideal for both solar (white light) and lunar imaging. as well as for live viewing/EAA (electronically assisted astronomy).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.
The camera uses Sony’s back-illuminated Exmor R technology, giving it excellent deep sky performance. ASI183 QE peak reaches a remarkable 84%. In Ha channel, QE is still over 60%.
A high QE means that the majority of the light that enters your telescope and reaches the sensor is actually used. With 84% peak Q.E. and no less than approximately 50% within the visible spectrum, the ASI183 will utilize a high percentage of the light that reaches it, significantly improving your signal quality.
Based on ZWO's own tests, the ASI294's dark current runs abit lower than the ASI1600 at the same temperature. Please check the dark frame to make sure you fully know its performance.
USB 3.0 Port & USB2.0 Hub:
- USB 3.0 Port: Provides 5Gb bandwidth to make it possible for ASI183 Pro to run at 19 fps (12bit, normal mode) or 19 fps (10bit, high speed mode) at full resolution(20.18Mega).
- USB 2.0 Hub: Easily compatible with various accessories (filter wheel, guide camera, electronic focuser) The USB hub can also be powered by an external power source. Includes 2 short 0.5m USB 2.0 cables.
The camera has a 2-stage TEC cooling system that enables deep cooling (40°C to 45°C below surroundings). This cooler will require an external power supply ot 9-15V batteries which are not included with the camera.
- M43-T2 adapter (optional)
- EOS-T2 adapter (optional)
- 2” Filter (optional)
- 1.25” T-Mount
- 1.25” Filter (optional)
- M42-1.25” adapter
- T2 extender 11mm
What's in the box:
* Note that cooled cameras need a 12V power adapter (which does not come with the camera)
* Please install the newest driver and software from the ZWO website before starting to shoot for best performance: https://astronomy-imaging-camera.com/software/
