ZWO ASI990MM Pro Cooled Camera

If you’re looking for a monochrome astrophotography camera that delivers sharp, detailed images with minimal noise, the ZWO ASI990MM Pro is a fantastic choice. Designed for deep-sky, and scientific imaging, this camera features a highly sensitive back-illuminated CMOS sensor, ultra-low read noise, and excellent quantum efficiency. Whether you’re capturing faint galaxies or intricate nebulae, the ASI990MM Pro provides the clarity and depth needed for stunning images.

With its 16-bit ADC, the camera preserves fine details and smooth tonal transitions, reducing noise while enhancing dynamic range. The built-in two-stage TEC cooling system keeps sensor temperatures low, helping to minimize thermal noise during long exposures. Paired with a filter wheel and LRGB or narrowband filters, this camera can take your astrophotography to the next level.

Designed for Deep-Sky and Planetary Imaging

The ASI990MM Pro’s sensor is engineered for astrophotography, offering high sensitivity and a low-noise profile. This means you can capture even the faintest details in deep-space objects while maintaining excellent contrast and resolution. The camera’s back-illuminated design improves light-gathering efficiency, making it easier to work with dim targets in challenging sky conditions.

Advanced Cooling for Long Exposure Imaging

Long exposures can introduce unwanted noise, but the ASI990MM Pro’s advanced cooling system helps keep things under control. The two-stage TEC cooling can drop the sensor temperature up to 35°C below ambient, significantly reducing thermal noise and improving image quality. A built-in dew heater prevents condensation, so you won’t have to worry about fogging up your sensor on humid nights.

Smooth Data Transfer and Reliable Performance

The ASI990MM Pro features USB 3.0 connectivity for quick image downloads, and the built-in 256MB DDR3 buffer helps ensure smooth data transfer with minimal dropped frames. This is especially useful when capturing high-resolution images or working with large datasets during long imaging sessions. The camera also offers adjustable gain and offset settings, giving you full control over exposure parameters for different targets.

Perfect for LRGB and Narrowband Imaging

Monochrome cameras offer better detail and flexibility than one-shot color cameras, and the ASI990MM Pro is no exception. Paired with LRGB or narrowband filters, this camera lets you capture images with greater depth and contrast. Narrowband imaging is particularly useful for cutting through light pollution and isolating specific wavelengths of light, making it easier to capture breathtaking details in emission nebulae and other deep-sky objects.

Why Choose the ASI990MM Pro?

• High-sensitivity monochrome sensor for capturing fine details in deep-space and planetary imaging
• 16-bit ADC for smooth gradients and enhanced dynamic range
• Ultra-low read noise to preserve subtle details in your images
• Advanced TEC cooling system for long-exposure imaging with reduced thermal noise
• USB 3.0 data transfer with a 256MB DDR3 buffer for reliable performance
• Ideal for use with LRGB and narrowband filters for high-contrast astrophotography

Take Your Imaging to the Next Level

If you’re serious about astrophotography and want a camera that delivers exceptional image quality, the ZWO ASI990MM Pro is a great investment. Its combination of high sensitivity, low noise, and advanced cooling makes it perfect for capturing deep-sky objects with incredible detail. Whether you’re just getting into monochrome imaging or looking to upgrade your current setup, this camera has everything you need for stunning astrophotography.
