For example, use sharpcap to connect a WDM-enabled camera, and the sharpcap display video image can be sent to other WDM-supported software for display, which is suitable for video online broadcast applications.

To avoid the problem of unreliable USB connection or port damage caused by leakage of computer or V to 12V adapter. Some computers or V to 12V adapters have leakage currents. If they are not well grounded, a high voltage is formed between the ground metal case of the USB interface and the ground metal case of the power supply line.

If the USB and power supply wires are in good contact with the camera, the device can operate normally due to the formation of a common ground at the camera. However, the common ground formed at the camera is very dangerous. On the one hand, it is easy to cause the USB connection to be unreliable, and the USB connection is often lost during use, and on the other hand, there is a risk of potentially damaging the port. Therefore, make sure the computer and adapter are well grounded before putting the device into service.

The method is not to connect the camera first, one meter is connected to the metal case of the USB plug, and the other meter is connected to the negative pole of the DC output plug of the power adapter generally inside and outside negative. If the voltage between the two is small, there is no leakage or a good ground has been achieved through the ground of the power plug. If there is a voltage of several V to several tens of V, there is leakage and there is no good grounding.

Need to check if the V power plug can provide a good ground. If there is no way to avoid it, you need to use a separate wire to connect the ground of the computer usually connected to the metal case and the negative pole of the V to 12V adapter to achieve common ground.

There is a hole in the side of the camera near the front plate that is normally plugged by a screw with an o-ring. If there is moisture in the CMOS chamber that causes the sensor glass to fog, you can connect the silica gel tube to this hole for drying the chamber. Place an effective silica gel desiccant in the silica tube make sure there is some cotton inside to prevent the silica gel from entering the CMOS chamber.

This coating can scratch easily so you should not use excessive force when cleaning dust from its surface. If the ambient humidity is very high, the optical window of the CMOS chamber may have condensation problems.

The QHY has a built-in heating plate to heat it to prevent fogging. In most cases, it is very effective. However, If fogging still persists, try the following: 1.

Avoid directing the camera towards the ground. The density of cold air is greater than the density of hot air. If the camera is facing down, cold air will be more accessible to the glass, causing it to cool down and fog.

Increase the temperature of the CMOS sensor. You can increase the temperature of the CMOS sensor slightly to prevent fogging of the glass. Check if the heating plate is working. If the heating plate is not working, the glass will be very easy to fog. If it does not reach this heat, it may be because the heating plate is damaged, you can contact us to replace the heating plate. You should avoid thermal shock during use. Thermal shock refers to the internal stress that the TE cooler has to withstand due to the thermal expansion and contraction when the temperature of the TEC suddenly rises or falls.

Thermal shock may shorten the life of the TEC or even damage it. If the power of the TEC is high before disconnecting the power supply, you should also gradually reduce the power of the TEC and then disconnect the power supply.

Anti-Dew Technology Based on almost year cooled camera design experience, The QHY cooled camera has implemented the fully dew control solutions. Readout Mode 2 Extended Fullwell Mode. Higher data rate. One 10Gigabit Fiber can transfer maximum 10Gbps data. While the USB3. Use the two 10Gigabit fiber can get about 1.

The data rate of these modes is much more than USB3. Very long transfer distance. The fiber is hundreds of times longer than USB3. For longer distances, it needs the extender cable but can just get 10meter to 15meter.

While the Fiber can transfer meter directly by default optic module comes with the QHY And if with the long-distance optic module, it can transfer up to 40km. Solid stable and no affected by EMI. One major factor that causes the camera to hang is the EMI issue. The USB3. Like the static and other high-power device emitted.

A long USB cable is easier to get this problem. Light can not be affected by the EMI. So with the fiber transfer, it will get everything very stable. Before Start: Input Voltage Requirements. Offset adjustment. When you completely block the camera i. Sometimes this will reduce the quality of the image contrast. You can get a better dark field by adjusting the offset. You can confirm this by opening the histogram as indicated in the figure below. After cooling devices connected to the 12V power supply, the temperature control circuit will be activated.

The UI design is quite cool. The SkyX Well-known as an full fuctional astroimaging platform. Just trust it! The aim is to line up the stars adjacent to the pole star with the on-screen overlay. You can also use the middle scroll wheel of your mouse if the mouse cursor is over the slider. At the end there should be a star visible in each of the red circle of the on-screen overlay.

If this is not the case, verify that you have indeed selected the correct star as the pole star. Choose a bright star adjacent to the pole star in the next step by double clicking it. To make the process more accurate, it is best to use a star that is not too close to the pole star. The on-screen instruction will prompt you to rotate the mount. In this step the application will try to determine the mechanical axis of rotation of your mount.

To do that, keep an eye on the bright star that you selected, while slewing your mount using your mount control usually the East button will rotate the mount in the direction required by the Application — some experimentation is required.

Rotate the mount such that the star moves by about 15 degrees. Repeat one more time. The Application will draw a green circle on the screen with the bright star on it.

The center of the circle is where the Application think the center of rotation is. Double click on the pole star again and match up the on-screen overlay as per the earlier step. On the screwn there is a small green circle. This is where your pole star should be. Use the mount azimuth and altitude adjustors, align the pole star with the green circle.

Fine polar alignment is achieved when the small green circle and small red circle become aligned. Please note there must be a star in each of the green box.

If there is no star in it, the pole axis position cannot be determined. The green circle will drift randomly as a result. After monitoring is started, as long as a GOTO has not been executed, the software will continuously determine the pole position frame by frame. If the mount is moved by accident and polar alignment is lost, the alignment can be restored by adjusting the mount to bring these two stars back into the green rectangle box.

The pole position will be determined again and you can further adjust the mount to get it well aligned again. After a GOTO, the stars will no longer be within the green boxes, but it is possible to rotate the green boxes to align them with the stars again manually. Before the electronic polar lens leaves the factory, the focal length has been adjusted.

If you find that the focal length is still incorrect and the star point is not fine enough, you need to readjust the focal length. The Raspberry Pi supports many versions of the system, such as linux, raspberry pi, windows, and so on.

The startup mode of the Raspberry Pi is to start the memory card. The kernel and system files written in the memory card are automatically loaded at startup. It is recommended to use 16G and above memory cards for image programming. The steps to program the system to the memory card are as follows:. Download the image file of the required system with the suffix. Mirroring, the system is based on Linux system;. Usually the program will automatically select the memory card device.

If it is not automatically selected or selected incorrectly, you need to select the correct memory card device at the Driver, click Format to start formatting the memory card, and the dialog box that pops up selects OK;.

The device usually does not need to be selected. If the software does not automatically select or select the error, you need to select it manually. Click the Select button. In the pop-up window, select the image file that you just unzipped. After selecting it, click the Write to start burning image.

During the programming process, the software will display the progress of the task. After waiting for a few minutes, the image will be burned. After the image is burned, connect the mouse, keyboard, monitor and power.

After power-on, the device will automatically run and run the mirror system in the memory card. The system needs to be set up for the first time, such as language, WiFi, device name, power-on password, etc. After the system is configured successfully, it will automatically enter the system interface.

Set the name and power-on password:. Once set up, the system will be installed automatically, and it will take a little time in the middle to wait patiently. The method of making a Raspberry Pi image is not unique. Other methods are also available, but you should pay attention to the Ubuntu MATE version of the image file. Other versions of the image are not supported. Modify the. If you use the sudo command after adding it, you will be prompted. Start the software and connect the camera.

After the camera is connected to the device, enter lsusb to see if the camera is recognized by the Raspberry Pi device and the firmware is loaded correctly. If the device of can be found in the display, the camera has been recognized and the firmware is loaded correctly. Otherwise, the camera will not be recognized. Please refer to the user manual for the software usage. Atmospheric condition will cause the apparent star position change slightly from time to time.
