Instruction

Congratulations and thank you for buying one of our ASI Cameras! This manual will give you a brief introduction to your ASI camera. Please take the time to read it thoroughly and if you have any other questions, please feel free to submit it on the ZWO support site:

The ASI432MM is one of the latest color planetary cameras released by ZWO in 2022. Packed with Sony sensor IMX432, this camera has some very great highlights, including a large sensor format of 1.1”, a large pixel size of 9.0um, and super-fast frame rate up to 120fps.

For software installation instructions and other technical information, please refer to our official website https://astronomy-imaging-camera.com/

Camera technical specifications

QE graph & Read noise

QE and Read noise are the most important parts to measure the performance of a camera.
Higher QE and Lower read noise are needed to improve the SNR of an image.

The following figure shows the QE curve of ASI432. According to our measurement, the QE peak of ASI432 is 79%.

Compared to traditional CCD cameras, the readout noise of ASI432 is extremely low. The built-in HCG mode can effectively reduce readout noise at high gain and allow the camera to maintain the same high dynamic range as it does at low gain. When the gain is 140, the HCG mode is automatically turned on and the dynamic range rises back to 12bit. When the gain is 400, the readout noise is 2.4e.

Amp glow

The IMX432 sensor has amp glow with itself but ZWO’s anti-amp glow function has greatly reduced it and maximized the camera’s photographic performance.
Please notice that ASI432MM still has amp glow. However, they can be easily calibrated with dark frames.

Getting to know your camera

External View

1. USB 3.0 & USB 2.0 Input
2. ST4 Guide port
3. AR Protective window D21*1mm
4. 1/4” screw: allowing you mount the camera to tripod.

Structural dimension diagram

Power consumption

ASI432 camera is built with low power consumption, max at 2.96W with USB power supply.

Protect window

There is a protective window AR filter in front of the ASI432 camera sensor, with 21mm diameter and 1mm thickness.

Analog to Digital Converter (ADC)

The ASI432 camera records in 12bit ADC and 10bit ADC. You can image at a faster fps rate if you use 10bit ADC (high speed mode). You can also set an ROI if you want even faster fps rate.
Below are the maximum speeds of ASI432 running at different ADC modes.

Binning

ASI432 camera supports software bin2, bin3 and bin4 mode and hardware bin2, bin3 and bin4 mode.
The biggest benefit is a faster frame rate. If you don’t care about speed, we suggest you use software binning.

How to use your camera

There are many adapters available for this camera for connecting to your scope or lens. Some are  included with the camera and others you can order from our site: https://astronomy-imaging-camera.com

1. 1.25” Nosepiece
2. 1.25” filter (optional)

Notice for use

Below are the requirements for camera storage and working temperature. Please don’t use your camera when the environment does not meet these requirements, otherwise the camera might get damaged.

Do not use corrosive solutions to clean the camera, so as not to corrode the surface oxide layer and not to damage the camera; Meanwhile, do not expose the camera to the sun for a long time, so as not to discolor the appearance of the oxide layer.

Cleaning

The camera is sealed and comes with an AR protect window to protect the sensor from dusts and humidity.
To see the dusts, you just need to set up your telescope and point it to a bright place. A Barlow is required to see these dusts clearly. Then attach the camera and adjust the exposure to make sure not overly exposed. You can see an image like below if it’s dirty.

The big dim spot on the image (right side) are the shadows of dust on the protect window.
The very small but very dark spot on the image (at left) are the shadows of the dusts on the sensor.
If above situation occurs, it is recommended that the dust on the sensor surface be blew off with air pump. If it cannot be blown off, it is recommended to use cotton swabs and 99% anhydrous ethanol to gently wipe the sensor.
