ZWO ASI462MM IR Sensitive Planetary and Lunar Imaging Camera

The ASI462MM features a highly sensitive sensor that images into the IR range and 256 mb internal DD3 memory.

STARVIS Technology

The STARVIS Technology improves the camera’s imaging performance in low-light conditions.

DDR3 Memory

The camera has a USB 3.0 transmission interface and built-in 256 mb DDR3 memory to ensure stable and secure data transmission. It effectively avoids frame dropping for long exposure and significantly reduces the glow effect caused by slow reading speed.

NOTE all ASI462MM IR cameras sold by FLO have built-in 256 mb DDR3 memory (the first 200 early-bird cameras did not). We do not provide memory upgrades for early-bird models.

USB 3.0 & ST4 Port

USB 3.0 Port: Provides 5Gb bandwidth to let the camera run at 136.1fps (10bit, high-speed mode) or 63.9fps (12bit, normal mode) at full resolution (2Mega).

ST4 Port: Can connect with a suitably specified mount’s auto-guiding port.

ASI462MM vs ASI290MM

As the upgraded version of ASI290MM, ASI462MM has greatly improved QE and readout noise.

Camera Performance

Low readout noise & high QE value

ASI462MM has an integrated HCG mode. This effectively reduces readout noise at high gain and enables the camera to maintain the same high dynamic range as low gain. At gain 80, the HCG mode is automatically turned on; the dynamic range reaches a level close to 12 stops, and the readout noise can be as low as 0.47e.

QE value and readout noise are some of the most important specifications for astronomical cameras. High QE and low readout noise are essential to improve image SNR(Signal to Noise Ratio).

The ASI462MM QE Peak value is around 89% (relative response)

AR Protective Window

ASI462MM features the AR(Anti-Reflective) coating on its protective glass. Diameter of the window: 21mm. Thickness: 1.1mm.
