AP183MM uses a SONY IMX183 CMOS sensor with Exmor and NIR Technology.

The ultra-low read noise is 0.5e- to 3e-, adopt unique hardware amplifier glow control circuit to significantly reduce amplifier glow, high sensitivity in IR range.

Best choice for astronomy and microscopy photography.




Photography Performance

The AP183MC (IMX183CQJ-J, Color) and AP183MM (IMX183CLK-J, Monochrome) use a 1-inch SONY back-illuminated sensor with 20.48 million pixels at 2.4um. The sensor has high sensitivity, QE of 84%, and its read noise as low as one electron. The full well capacity is 15-15100 electrons.

IMX183CQJ-4K-Sensor, High-Speed and High-Picture-Quality, Rolling Shutter, Diagonal 15.86 mm

At an affordable price, this camera is ideal for beginners and experienced astrophotographers. It is bestseller products in astronomic imaging application. Very large scale of full well capacity(15100e), 1.62e read noise@30DB, adopt unique hardware amplifier glow control circuit to significantly reduce amplifier glow, in order to get excellent performance in astrophotography.

The “lucky imaging” method used in planetary imaging uses many short exposures to freeze the effects of atmospheric scintillation. Multiple short exposures instead of one long exposure can better freeze this movement. The stacking software will filter out the images taken during poor moments of seeing, and retain those taken at the good time. Therefore, before the rotation of the planet becomes a factor, people need to take as many images as possible in a short time. Therefore, a high frame rate is very important for planetary imaging.

High QE

Sony’s back-illuminated Exmor R technology creates its excellent deep space performance. The AP183 QE peak reached a significant 84%. Even in the Ha channel, QE still exceeds 60%.

High QE means that more light that enters the telescope and reaches the sensor which is actually used. The peak Q.E. of AP183 is 84%, which is not lower than ~50% in the visible spectrum range. It will use a high percentage of light to reach it and enhance your signal quality.

High Speed

Fast FPS can be used for solar and moon imaging, as well as live viewing/EAA. That high-speed readout can also be used for real-time focusing, true lucky imaging of binary stars and other small celestial bodies, planetary imaging of major planets in the solar system, and so on.
