01 Software Installation

1. Download and install ASCOM platform

2. Download and install Camera Driver

3. Download and install ASCOM Driver

As you most probably want to use your QHY367C as an expose camera, please download the
Capture version. If you want to use it as a guide camera, please download the Guide version.

4. QHY367C camera uses SharpCap as the default capture software. Please download SharpCap.
QHY367C camera can run on SharpCap 2.9 or later versions
Note that QHY367C requires the latest qhyccd.dll for the new version of SharpCap, and QHYCCD
has already developed a software named SharpCap Patch for it. You should download and install it
prior to using SharpCap.

5. Connect QHY367C to your PC with USB3.0 cable. Connect your QHY367C to 12V power supply
(Make sure 12V power supply is always connected when you use QHY367C). For the first time the
system will find a new device and search the driver. You can skip the online searching by clicking
“Skip obtaining driver software from Windows Update” and the computer will find the drivers.

After installation is complete successfully, you can find the device in the device manager as shown
in the picture below.

6. QHYCCD has developed a software named UpdateCheck that can check if the drivers

installed on your computer are the latest versions as well as update the drivers if needed. If the

status of some driver is “Need Update”, you can directly download its update package in this

software freeing you from the inconvenience of looking for and downloading it from our website.

Take QHY367C for example, you can see the drivers we need are the latest versions and don’t

need to be updated as shown in the following picture.

Note that after you downloading and installing the new drivers by using this software, be sure to

pull the USB cable out and then plug it in to enable the new drivers.

02 Use QHY367C in SharpCap

1. Connect your QHY367C to 12V power supply. Connect your QHY367C to your computer with

USB3.0 cable.

2. Run SharpCap. If the aforementioned software and drivers all have been installed properly,

the video image will appear automatically and you will see the frame rate at the lower-left
corner of the software as shown below

3. If you have started the SharpCap before connecting camera to your PC. You can click

menu->cameras->rescan for cameras to search the camera and check on the camera name
(QHY367C in this case).

4. To make sure the camera can run properly, the software will start the camera at the lowest

speed, which makes the frame rate much lower than the highest frame rate declared on its
webpage. Now you can try to get the most out of it by changing several settings. First you
can try to set the exposure time to 1ms, then try to reduce the “USB traffic” value. For
modern computer with i7-4 core, it should get the max performance. But please note that
not all computers can get the best performance due to various reasons such as the CPU
loading, the saving-energy mode setting, the mainboard performance and USB3.0 port
performance. Sometimes the display size may also impede obtaining the best performance.
So you can try to use the “Zoom” function to reduce the display size to see if it helps.

5. Adjust the offset. When you block the light thoroughly, you may find that the image is not

really “zero” (entirely black). Sometimes this will lower the quality of image contrast. You
can adjust the offset to make the histogram peak close to zero in order to get a better
background. You can open the histogram to confirm that.

6. If you want to try 16bit image, you can switch the Colour Space to “RAW16”.

7. By check the “LX” mode you can expand the exposure setting range and take long exposure

shot. QHY367C camera has the anti-amp light control circuit and it can reduce the amplifier
glow significantly. Note that it’s impossible to reduce the glow in the corner thoroughly, and
it’s normal to see a very small amount of glow in the corner when you do long exposure.

A typical long exposure image in 5℃, 5 sec exposure and 40 gain of QHY367C is shown
below.

8. After you connect 12V power supply for QHY367C to power the TEC cooling circuit, you can

set the CMOS sensor cooling temperature in the “Thermal Controls” section in SharpCap as
shown in the following picture.

Basically, you can control the temperature of CMOS by either adjusting “Cooler Power” or
clicking “Auto” and adjusting “Target Temperature”. You can also see the CMOS temperature
at lower-left corner of the software.
Before use this function, you should read the content about how to protect the cooler in the
FAQ section.
