Technical data sheet
ZWO ASI294MM Pro – 4/3” Monochrome Astronomical Camera with TEC Cooling
The ZWO ASI294MM Pro is a cooled monochrome astronomical camera based on the 4/3” Sony IMX492 sensor with 4.63 µm pixels. Ideal for high-sensitivity narrowband and luminance deep-sky astrophotography, it offers great color depth, high full-well capacity, and excellent quantum efficiency.
Key Features
- Sony IMX492 monochrome sensor, 4/3” format.
- Large 4.63 µm pixels for high sensitivity.
- Full-Well Capacity up to 66k e⁻ for non-saturated stars.
- HCG mode for noise reduction and maximum dynamic range.
- Very high QE → ideal for narrowband filters.
- Dual-stage TEC cooling down to -35°C.
- USB 3.0 + 256 MB DDR3 buffer.
- Zero amp-glow → extremely clean dark calibration.
- Compatible with ASIAIR, NINA, Voyager, SharpCap, and other software.
- Robust aluminum body with anti-dew system.
Optical performance for deep-sky and narrowband
The ASI294MM Pro is highly regarded for narrowband astrophotography (Hα, OIII, SII) thanks to its high sensitivity, large pixels, and extremely low noise. Perfect for diffuse nebulae, HII regions, galaxies, and advanced imaging projects.
Professional TEC cooling
The dual-stage TEC module reduces the sensor temperature by up to -35°C, limiting thermal noise and improving the quality of long exposures.
Robust design with DDR3 buffer
The 256 MB DDR3 buffer ensures stable data transfer, avoiding dropped frames or issues during long-exposure imaging. The CNC aluminum body ensures rigidity and optimal heat dissipation.
