It is the mono version of ASI294MC Pro, one of the top selling cameras from ZWO. It has an impressive 66ke- full well capacity and 4144*2822 big resolution.\u003c\/p\u003e\n\u003cp\u003eNot only does it have a very high QE value with a peak at about 90%, but feature an ultra-low readout noise of 1.2e.

It has retained the advantages of CMOS image sensors such as low power consumption and high-speed operation.\u003c\/p\u003e\n\u003cp\u003eWith 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.\u003c\/p\u003e\n\u003ch4\u003eCamera Performance\u003c\/h4\u003e\n\u003cp\u003eLarge well depth capacity, low read-out noise and high dynamic range.\u003c\/p\u003e\n\u003cp\u003eThe full well capacity of 66387e of ASI294MM Pro is near the top of all ASI DSO cameras. It ensures a very high dynamic range up to 13stops that will greatly reduce overexposure probability and help gain richer color gradation.\u003c\/p\u003e\n\u003cp\u003eWhen the gain value is 120, the magical HCG high gain mode is turned on, the readout noise will be largely decreased (as low as 1.2e), and the dynamic range is basically unchanged.\u003c\/p\u003e\n\u003ch4\u003eReliable Mechanics\u003c\/h4\u003e\n\u003cp\u003eThere are four screws on the camera that seal the sensor chamber.

Even when used in higher humidity environments, ASI294MM Pro will still work fine without dew problems.\u003c\/p\u003e\n\u003cp\u003eIn addition, ASI294MM Pro also has a polyimide anti-dew heater completely fitting the protective window that will help further avoid dew problems.\u003c\/p\u003e\n\u003cp\u003eThe anti-dew heater power is around 5W and can be turn off in software to save power.\u003c\/p\u003e\n\u003ch4\u003eQE Value\u003c\/h4\u003e\n\u003cp\u003eAs ZWO’s latest BSI (backside illuminated type) mono camera, ASI294MM Pro has very high QE performance, not only higher than its color version, but even ASI1600MM Pro.
