Description
ZWO ASI461MM Pro Overview
Capture stunning, high-resolution images of deep-sky objects with the ASI461MM Pro USB3.0 Cooled Mono Astronomy Camera from ZWO. Equipped with a medium format Sony IMX461 monochrome CMOS sensor, the camera achieves 11656 x 8750 resolution with low read noise and no amp glow. The two-stage thermoelectric cooler lowers the temperature to 95°F below ambient, all but eliminating dark current noise for a clean image even with very long exposures. The polyimide heater prevents pesky condensation from interrupting your imaging, but you can also turn it off to save power. Speaking of power, you'll need a 12V 3A power supply, 5.5 x 2.1mm, center-positive.
100MP CMOS Sensor
The ASI461MM Pro features a large 44 x 33mm Sony sensor with a resolution of 11656 x 8750. The 3.76µ pixel accommodates an impressive full well capacity of 50.3ke. In Bin2 mode, the full well capacity is expanded to 198ke, and the pixel size expands to 7.5 x 7.5µ. The sensor boasts a quantum efficiency of 90% and a 16-bit analog-digital converter.
No Amp Glow
Using zero-glow amp circuitry, the ASI461MM Pro eliminates amp glow�a weak infrared light source often created by traditional CMOS sensors, sometimes seen in the corners of uncalibrated images. You won't have to worry about it, even during high-gain, long-exposure imaging.
Anti-Dew Heater
A polyimide heater sits on the top of the protective window, preventing condensation that will disrupt your process. It consumes about 5W and can be disabled to conserve power.
High Conversion Gain Mode
HCG mode comes on automatically when gain is set to 100 and keeps readout noise very low while maintaining the 14-stop dynamic range.
Two-Stage TEC Cooling
The sensor can be cooled to 95°F below the ambient temperature, holding down dark current noise. When the sensor is cooled to 32°F, a 300-second exposure only 0.7e dark current noise in total, even lower than the camera's readout noise.
USB 3.0 & 2.0 Connectivity
The camera features a USB-B 3.0 port for data transfer to your computer and two USB-A 2.0 ports for connecting to a guide camera or electronic filter wheel.
