Overview
The ZWO ASI294MM Pro Is a High-Performance Monochrome Deep Sky Imaging Camera Featuring a Back-Illuminated Sony IMX492 CMOS Sensor, 14-Bit ADC, Switchable Pixel Modes, Ultra-Low Readout Noise, and a Full Well Capacity of Up To 66,387 Electrons, Engineered for High Dynamic Range Astrophotography Across a Wide Range of Telescope Configurations.
Capture Stunning, High-Resolution Images of Deep-Sky Objects with the ASI294MM Pro USB 3.0 Cooled Colour Astronomy Camera From ZWO.
Equipped With a Square Sony IMX492 CMOS Sensor, the Camera Achieves 11.7MP Resolution with Low Read Noise and Amp Glow.
The Two-Stage Thermoelectric Cooler Lowers the Sensor Temperature By 95°F Below Ambient, Dramatically Reducing Dark Current Noise for a Clean Image Even with Very Long Exposures.
Cooling Also Allows You To Match Your Calibration Frames To Your Imaging For Optimal Signal-To-Noise Ratio.
The Camera Runs On a User-Supplied 12V 35A Power Supply.
