ϭDriver and software installation (Windows)

1. Download and install “Cameras driver”from our website

https://astronomy-imaging-camera.com/software/ or CD-ROM.

After plugging in the camera, you will see your ZWO camera model listed

under the “imaging devices” category of the Device Manager if the driver

is installed successfully.

2. Download and install SharpCap (image capture software) from our

website or CD-ROM. Choose your camera modelfrom the cameramenu.

Then you can see the preview video. Keep in mind that you will only see

some brightness in the preview video without lens or scope.

More detailed user manual can be found at our website:

Trouble shooting:

1. The preview image is completely white but the fps is normal.

The camera is over exposed, please reduce the exposure and/or gain.

Keep in mind that you can only see brightness without lens or scope

2. The preview screen is black and the fps is “0”.

Please try to slow down the capture speed by reducing the “Turbo USB”.

Also try connecting the camera to your PC directly without a USB hub or

extender if reducing “Turbo USB” still does not work.

3. The camera can`t preview at the FPS declared in the specifications.

1) Please make sure the camera is connected to USB3.0 host if it’s a

USB3.0 camera. Check that the camera is recognized as “via USB3.0”.

Please try to update the computer`s USB Host Controller driver if not.

2) Make sure that the “High Speed Mode” is On.

3) Adjust “Turbo USB”, we recommend 80-90%. This value depends on

your computer, higher means faster.

4) Don`t forget the exposure time affects FPS too. In general your

exposure time needs to be shorter than 1/FPS rate. For example, the

FPS will decrease to 1FPS when the exposure time is 1 second.

4. The camera can preview at 60fps but drops to 20fps when recording.

This is because your hard disk drive cannot match the speed of the

camera. Most ASI cameras are very fast and require up to 400M/s data

transfer speed. But most hard disk driver can only run at 40-50M/s.

We recommend you can exchange your HDD with one fast SSD and try

to capture the data in raw format instead of RGB24 if you use one color

camera.

5. The camera cannot run continually on a laptop without external power

This is because of the power save mode of your laptop, you need to

disable power saving of USB port.

6. There is a yellow hint with the camera model name and error code 10.

You may have this problem with our USB2.0 cameras, please try

another USB Port or PC, then you can upgrade the firmware of this

camera onthe good PC. The original firmware is more stable and faster.

Download this upgrade tool from our website

7. Unknown device shown under the device manager after plugging in the

camera.

This is because the driver in not installed or installed properly, please try

to close all anti-virus software and re-install the driver.

You can also update the driver manually if re-installation still does not

work.

Right click the “Unknown device”, choose the “Update Driver Software”

and point to the driver directory. Normally the driver directory is :

C:\Program Files (x86)\ZWO Design\ZWO_USB_Cameras_driver.

Why do I choose T7 Camera Astronomy Planetary?

It is mostly used for planetary imaging. It can also be used for deep sky imaging up to a certain

level. This new version comes with an ST4 Auto guider Port, so you may now use it both for

imaging and guiding.

Monochrome camera sensors are capable of higher details and sensitivity than color sensors, but

you need additional accessories such as filters. The post-processing is more complicated too. So

color camera is often recommended for beginner of astrophotographer.
