Zero amp glow — yes, really.

While amp glow can be managed with processing techniques, wouldn’t it be better if it didn’t exist at all? With the ASI533MC-PRO, that’s exactly what you get: clean frames, no fuss.

But that’s just the start. This camera offers impressively high quantum efficiency, ultra-low read noise, and a relatively fast frame rate — perfect for a wide range of imaging styles.

Like the popular ASI1600MC and ASI294MC models, the ASI533MC-PRO is a solid choice for deep sky imaging. But thanks to its 20 FPS maximum frame rate at 14-bit ADC, it also performs exceptionally well for high-resolution planetary work. If you're torn between targeting nebulae or shooting Jupiter in detail, this versatile camera handles both. It’s also a far more cost-effective solution than converting a DSLR.

This version includes a colour sensor only and comes with integrated two-stage TEC cooling. (A non-cooled model is not offered.)

Its specs are similar to the ASI183MC-PRO, but with larger pixels and a slightly lower resolution. For compact, widefield achromats or small APOs, the ASI183MC-PRO remains a great fit. But if you're using a slightly larger apochromat, the ASI533MC-PRO pairs beautifully.

In the ZWO colour lineup, this camera sits right between the ASI294MC-PRO and ASI183MC-PRO — making it a smart, balanced choice for anyone serious about colour imaging.

Features of the NEW ZWO ASI533MC-PRO

Camera Sensor

▶IMX533

1” square sensor

The IMX533 comes with a 1-inch, 9MP CMOS image sensor in a square format with a 3.76 um pixel size, capable of producing frames at 20 frames/sec in 14bit mode.

Read out noise is as low as 1.0e which makes it comparable to SCMOS or EMCCD sensors and highly suitable for high definition, low noise imaging.

IMX533 backlit sensor

Sony’s back-illuminated CMOS image sensor improves sensitivity and noise reduction – the key factors to enhancing image quality, while radically realigning their fundamental pixel structure from front-illumination to back-illumination. It has retained the advantages of CMOS image sensors such as low power consumption and high-speed operation.

With a conventional front-illumination structure, the metal wiring and transistors on the surface of the silicon substrate that form the sensor’s light-sensitive area (photo-diode) impede photon gathering carried out by the on-chip lens. A back-illuminated structure minimizes the degradation of sensitivity to optical angle response, while also increasing the amount of light that enters each pixel due to the lack of obstacles such as metal wiring and transistors that have been moved to the reverse of the silicon substrate.
Sony has newly developed a unique photo-diode structure and on-chip lens optimized for back-illuminated structures, that achieves a higher sensitivity and a lower random noise without light by reducing noise, dark current and defect pixels compared to the conventional front-illuminated structure. 

Camera Performance

Low read-out noise, high dynamic range.

QE Curve

We suppose the QE peak value is more than 80%.

Zero Amp Glow

Traditional CMOS sensors produce a weak infrared light source during operation quite often seen in the corner of uncalibrated images as the tell tale signs of ‘amp glow’. As the ASI533MC PRO uses zero amp glow circuitry, you won’t have to worry about amp glow even when using high gain, long exposure imaging.

DDR Memory Buffer

The ASI533MC PRO is equipped with a USB 3.0 interface, and even in 14bit mode, can reach 20 frames per second. The 256MB DDR3 memory ensures stable downloading of frames with increased USB speeds. 

ASI533MC Pro – ASI183MC Pro Comparision

The ASI533MC PRO features SONY’s latest back illuminated IMX533 sensor, with a 1-inch square, 9.07MP sensor that is ideal for astronomical photography needs and can be considered as the latest iteration of the venerable ASI183MC Pro.

As you would expect this latest generation camera not only retains key features of the ASI183 series such as an attractive QE figure, high frame rate and along with other excellent characteristics of the ASI183 cameras, but also now includes new and improved features such as zero amp glow, extreme low read out noise (as low as 1.0e), 3.76 microns pixel size and an improved 2 stage TEC cooler giving enhanced cooling capabilities.
