Description
The ZWO ASI 183 chamber has great potential and offers countless new possibilities! It is suitable for both deep-sky and lunar and planetary imaging.
The ASI 183 series includes the most sensitive cameras in the history of the ZWO brand. The maximum quantum efficiency of the mono-sensor is 84%!
Perfect for astrophotography
In addition to the Sony IMX183CLK-J (monochrome) and IMX183CQJ-J (colour) sensor, specific for astronomical use is the structure equipped with back illumination (BSI) and very small 2.4 µm pixels. Despite this, the ASI 183 chambers have a particularly high Full Well Capacity of 15,000 electrons.
Sony Exmor technology makes this camera perfect for deep sky photography. The sensor reaches a quantum efficiency of 84%, and in H-alpha it still remains above 60%. A high quantum efficiency means that more of the light collected by the telescope actually reaches the sensor, with a marked improvement in the images.
High Speed
A high frame rate is useful for solar and lunar photography. The high readout speed supports both real-time focusing and the Lucky-Imaging procedure for taking double star and planetary images.

Special features of the ZWO ASI Pro chambers:
ASI Pro cameras are equipped with a 256 Mbyte DDR3 buffer memory, which ensures reliable data transfer and reduces the so-called amp-glow, which can occur with the slower USB 2.0 interface.
The ASI Pro can count on an optimized camera body. Four screws reliably close the sensor compartment. The design has been thoroughly tested and proven to be extremely robust. Even in conditions of high humidity, the chamber does not show fogging due to condensation.
To allow breathtaking deep-sky shooting, the ASI Pro cameras are also equipped with a two-cell Peltier cooling system, which guarantees sensor temperatures from 40 to 45° C below the ambient temperature. For this the noise is greatly reduced.
ZWO ASI chambers with active cooling require an additional 12 volt power supply. If you do not have a suitable cable, you can find it among the recommended accessories.
Color or monochrome? Black and white cameras have the advantage of being more sensitive and having a higher resolution than color cameras. However, the expense of color images is high, as filters and a filter wheel are required.
