QHY16200A
01 Software Installation
1. Download and install ASCOM platform
2. Download and install the Camera Driver
Note that when you run its driver setup program, you will be prompted to install camera driver,
network card driver, and FTDI Serial port driver. Since IC16200A and QHY16200A use the same
system driver and there's no network card in the QHY16200A, the network driver is actually no
use.
3. Download and install the ASCOM Capture Driver
4. Download and install the ASCOM Filters Plug for the built-in filter wheel.
5. QHY16200A camera uses EZCAP_QT as the default capture software. Please download and
install EZCAP_QT.
6. Connect QHY16200A to your PC with USB2.0 cable. Connect your QHY16200A to 12V power
supply (Make sure 12V power supply is always connected when you use QHY16200A). Note
that there are two power ports on QHY168200A, and these two ports are connected in parallel,
so you can either one of these two as power input port and use the other one as a power output
port for other devices that need 12V power supply. Turn the switch on. For the first time the
system will find a new device and search the driver. You can keep skipping 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.
7. 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 QHY183C 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.

QHY16200A
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.

QHY16200A
02 Filter installation
QHY16200A has two versions now. One contains a built-in 5-Hole 50mm filter wheel, and the
other has a built-in 7-hole filter wheel. Please follow the instructions below to install filters for it.
1. Use the screwdriver included in the box to remove the screws on the topside of the camera.
2. You can see the filter wheel after opening the top cap. You can install 50mm filters and fix
them with screws and washers. Please make sure that filters and screws used for fixing the filters
do not touch the top cap and photoelectric position detector.
3. After you've finished installing the filters, you can turn on the camera and connect the camera
to your PC with USB cable to make sure the filter wheel can work properly. Note that the filter
wheel use photoelectric position detector to determine the position of the filter, so make sure
you are not exposing the filter wheel to strong light when you are testing if it can work properly,
otherwise the strong light may affect the photoelectric position detector.
4. Install the top cap.
Now we have finished installing filters, we are going to introduce how to use QHY16200A in
EZCAP_QT, MAXIMDL, and Sequence Generator Pro.

03 Use QHY16200A in EZCAP_QT
EZCAP_QT is the software developed by QHYCCD. This software has the basic capture function
for QHYCCD deep sky cameras. You can use this QHY16200A camera with its built-in filter wheel
in this software.
1. Install EZCAP_QT
2. Connect your QHY16200A to 12V power supply. Connect your QHY16200A to your computer
with USB2.0 cable.
3. Run EZCAP_QT. Select "Connect" in Menu->Camera. If the camera is successfully connected.
The title of EZCAP_QT will display the camera firmware version and the camera ID as shown
below.
Before you click "connect", you have to make sure you can see QHY16200A in the device
manager on Windows. Sometimes if you click "connect", you may see the warning shown in the
picture below.

QHY16200A
That doesn't necessarily mean that the camera and your computer are not connected. In this
case, you can just wait for a minute and click 'connect' again, then you can see it will be
connected successfully. This is because it usually takes a while to load its firmware into your
computer.
4. In Menu->Camera Setup, Click "Temp Control" and set the CMOS sensor temperature. You can
enable the "Auto Control" and set the target temperature. For example here we set the
temperature to -10C. The CMOS temperature will come to -10C very fast (in about 2-3minute). If
you want to close the TEC, you can select "TEC OFF". If you just want to set the TEC power but
not the temperature. You can select "Manual" and then set the percent of the TEC power.
The CCD of QHY16200A is very big, so it takes a while to achieve the target temperature. Be
patient while you are waiting.
5. You can select which filter you are going to use by changing the position of filter wheel as
shown in the following picture.

QHY16200A
6. You can use the preview tab to do preview. And use the focus tools to do focus. Then use the
capture tab to capture image.
7. In EZCAP_QT there is a planner for image tasking. You can capture a series images by using the
table below.
8. Typical QHY16200A Dark/Flat/Calibrated Images with Grade2 sensor
This is a typical Dark Frame at 300sec exposure, -15C, gain=0. Part of the image. 1:1 zoom

QHY16200A
Stretch to background level
Stretch to Max Range
A typical 10sec 4*4binning Dark Frame with all the region of the image. The vertical blank
banding on the right of the image is the overscan area. The overscan area is important for
overscan calibration. We recommend you reserve this area. You can also see two strip that is a
little brighter than the image area. It is the "Optic Black" Area.
The difference of "Optic Black" Area and "Overscan" Area is that the "Optic Black" area has a
metal shield on it and it is not sensitive to light, But thermal current still exists. The "Overscan"
area is a virtual area and it represents the bias.

04 Use QHY16200A on ASCOM platform
You can connect many software that support ASCOM. Currently QHY16200A only supports
normal ASCOM connection and does not support the ASCOM VIDEO connection. Please note that
QHY16200A always transfers maximum bit depth by ASCOM to make the best DSO imaging
performance. The image format is 16bit width and patch zero on low bit.
MaxIM DL
1. First you have to make sure that both ASCOM Platform and ASCOM driver have been installed.
If not, please install it first.
2. Start MAXIMDL
3. Follow the instructions shown below to finish the setup.

QHY16200A
Normally, you can set the gain=1 and offset=10 to start. Keep clicking "Okay" to return to Camera
Control window.
The following instructions are going to show you how to configure the built-in filter wheel in
MAXIMDL.
Click "Setup Filter" in the Camera Control window.

QHY16200A
In the window shown below, you can set up your filter wheel.

QHY16200A
Keep clicking "OK" to return to the Camera Control window. Click "Connect"

Sequence Generator Pro
Sequence Generator Pro is an extremely powerful image capture suite. It can perform many
complex tasks in order to meet your imaging needs. After you connect your gears and configure
Sequence Generator Pro properly, you can go to sleep and see images in the morning.
To use QHY16200A in Sequence Generator Pro, you can follow the instructions listed below.
Open sequencer by clicking the button in the red rectangle as shown in the picture below.
If you've connected QHY16200A to your PC before click that red button. The red button will turn
to green as shown in the picture below.

QHY16200A
The next step is going to configure the built-in filter wheel. Before you select QHYCCD Filter
wheel as the filter and click the red connect button, you should also make sure you've
downloaded and installed the ASCOM Filters Plug for the built-in filter wheel, you've plugged in
the 12V power supply cable, and the initialization of filter wheel has been finished.

QHY16200A
For example, you can change the filter names to Lum, Red, Green, Blue, and Ha as you installed
them this way. Then you make schedule events to take turns to use these filters as shown in the
following picture.
