Also, on the sale, you can enjoy discounts of up to 22% off on selected models. Let’s dive into the world of cooled cameras and discover the perfect one for your needs!

1.What are Cooled Cameras?

The ZWO cooled cameras are perfect for taking longer exposure images of the night sky. Their cooling ensures optimal performance for deep sky imaging!

Cooling allows the camera sensor to become many degrees colder than ambient temperature, which in turn greatly reduces noise in the final image. This gives a large advantage over DSLR and mirrorless cameras for astrophotography.

Also, the cooled cameras allow for longer exposure times without the risk of excessive heat accumulation. This is crucial when imaging dim astronomical targets, as longer exposures gather more light and reveal finer details.

2.Entry-level Cameras

The ASI533MC-Pro is a great choice for new beginners to step into deep sky imaging. For beginners committed to deep-sky observing and who want to jump right away into a ZWO cooled camera, the ASI533MC-Pro is the best place to start.

The ASI533MC Pro camera features Sony’s back-illuminated IMX533 sensor, high sensitivity and zero amp glow.

The ASI533MC Pro has low readout noise, high dynamic range, and its readout noise is as low as 1.0e.

The key feature of this camera is zero amp glow. You don’t have to worry about amp glow even when using high gain, long exposure imaging. This makes it ideal for astronomical photography. 

Also, the square CMOS sensor makes it more convenient to take photographs.

There is no need to turn the camera significantly to make the long side conform to the direction of an elliptical galaxy, which will avoid causing problems with the system. A slight rotation of the square sensor within 45°can be enough to find the best framing direction.

3.Advanced cameras

If you have the aspiration to go deeper into deep sky imaging, then the ASI2600MC/MM also be a camera you want to try.

The ASI2600MC Pro uses Sony’s back-illuminated IMX571 APS-C format sensor with a native 16-bit ADC. It is the color version of the ASI2600MM Pro. It has an impressive range of features that make it a popular choice for astrophotographer.

The ASI2600MC Pro has ultra-low 0e- readout noise, 16-bit ADC sensor, it can significantly improve the image sharpness and contrast, and also create smoother and more natural color transitions.

Also, we recommend you the ASI2600MM.

This camera is the mono version of the ASI2600MC Pro, the QE peak value of the ASI2600MM Pro is 91%.

A color astronomy camera allows you to capture full-color images of deep sky objects in a single shot, without the need for additional filters or extensive processing. However, using color cameras limits the ability to incorporate information from colors outside the visible spectrum, such as infrared data, which could enhance the image. Additionally, working with narrow-band filters may result in some loss of image sharpness.

Many serious astrophotographers prefer mono cameras for their best work. Mono cameras produce single-color images that can be combined later using filters to create detailed full-color images. While working with mono cameras requires more time and additional equipment, such as filters and a filter wheel, it allows for greater control and detail in capturing deep sky objects.

If you prioritize convenience and speed or are new to astrophotography, color camera is a suitable choice. If budget permits and you want to capture best image, the mono cameras are an excellent option.

4.High-end cameras

If you have enough budget for a cooled camera with standout features, the ASI6200MC/MM is worth considering.

The ASI6200MC Pro uses Sony’s back-illuminated IMX455 full frame format native 16-bit ADC sensor. It has 3.76µm, ultra-low 1.2e readout noise and an innovative breakthrough that results in zero amp-glow.

The camera can provide exceptional image quality and high sensitivity to capture intricate details of celestial objects. The cooling performance is remarkable. The ASI6200MC Pro’s robust structure and advanced features make it a preferred choice for astrophotographers looking to capture stunning deep sky images with remarkable clarity and detail.
