AstroDMx Capture running under Fedora 26 / Cinnamon. The dark theme has been inherited from the Cinnamon desktop theme.
The latest version of AstroDMx Capture for Linux is 0.10.2.0. The software is now distributed in three packages and can be downloaded by clicking the following links.
- astrodmx_capture version 0.10.2.0 - Debian Installer (DEB)
- astrodmx_capture version 0.10.2.0 - RPM Installer (RPM)
- astrodmx_capture version 0.10.2.0 - Manual Installer
The manual installer's tarball contains a readme file which explains how to install the software. The RPM and DEB can be installed in the usual way (either via the GUI or via the command-line). If the options to start AstroDMx Capture do not appear in the system's menus then logout and log back in. The software can be uninstalled by using the following standard procedure:
- Fedora: yum remove AstroDMx_Capture
- Debian: dpkg --remove astrodmx_capture
If the software fails to run then drop to a command prompt and execute the following commands. The error messages will show what is causing the problem, for example, if you have missing dependencies.
- cd /usr/local/AstroDMx_Capture/bin
- ./astrodmx_capture -D
If the software throws a segmentation fault on startup (discovered from the procedure above) and you have had a previous version installed then you might have to delete the configuration file as detailed below and then rerun the software.
- Do NOT do the following as root.
- cd $HOME/.AstroDMx
- rm config
Some Linux distributions do not support SELinux. While AstroDMx Capture does not directly use SELinux it does require the libselinux.so.1 library to run. If you have such a distribution then you will need to use our dummy SELinux library; details of which follow:
RPM Installation - Missing SELinux Dependency
If installing via the RPM package and your system does not have SELinux then you will need to install the RPM from the command-line by typing the following command before downloading the dummy SELinux library below:
- rpm --nodeps -ivh AstroDMx_Capture*.rpm
Please note, installing an RPM without dependency checking will allow the application to install regardless of the system's dependencies. Therefore, it is possible that you might have to manually check to see which dependencies are missing and then install them via your distributions package management system.
If the software fails to run because libselinux.so.1 is missing (details obtained from running the software from the command-line) then download the archive below. This download is not an implementation of SELinux, instead it simply supplies the required dependency and reports back to AstroDMx Capture that SELinux is not available and so allows the software to run.
Once downloaded, extract the archive and copy it to /usr/local/AstroDMx_Capture/lib
Known Issues (version 0.10.2.0)
Due to an issue with the ZWO SDK, the heartbeat monitor does not work and will be automatically disabled when a ZWO camera is connected. If the ZWO camera goes offline, for example, due to a bad USB bandwidth setting, the camera will not automatically reset. If this happens then the user will need to reconnect the camera and then restart the software. All other cameras will be automatically reset and continue from the previous settings if they encounter a issue which causes them to go offline, for example, a loose USB cable.
All Versions: If multiple camera controls are changed during a long exposure then the last control will take effect, all others will be cancelled. For example, if the user changes the exposure to one minute and then immediately changes the gain, then the exposure control will be cancelled. To avoid this issue, change one control and wait for the exposure to complete. This behaviour will be changed in a future version.
32-bit versions, including a version compiled for the Raspberry PI3, will be released in due course.

Important Note: DFK / DBK cameras on modern computers
Imaging Source colour CCD cameras, such as the DFK-21AU04.AS do not work correctly on some modern computers. For example, the Imaging Source camera mentioned is able to stream normally but the camera controls do not work when using YUYV. The simplest solution to this problem is to use the camera's Bayer mode (which works perfectly and has higher frame rates) but if YUYV is important to the user then the following may help.
Generally, computers have both an xHCI and an EHCI controller and the camera mentioned above does not work correctly with the xHCI controller.
The following procedure will cause the xHCI controller to forward USB 2 packets to the EHCI controller which solves this problem. However, it is important to note that some very new computers are no longer shipped with a EHCI controller. In this case this procedure will not work. In such a case, the DFK-21AU04.AS will only work correctly in its Bayer or Greysclae modes.
Drop to a command prompt and execute the following commands as root. This can be done by typing su or by prefixing the commands with sudo.
- lspci -nn | grep USB
The output will look something like the following, the exact output will be dependent upon your hardware. Do not use the information from this sample because it will not work on your system.
00:14.0 USB controller [0c03]: Intel Corporation 7 Series/C210 Series Chipset Family USB xHCI Host Controller [8086:1e31] (rev 04)
00:1a.0 USB controller [0c03]: Intel Corporation 7 Series/C216 Chipset Family USB Enhanced Host Controller #2 [8086:1e2d] (rev 04)
00:1d.0 USB controller [0c03]: Intel Corporation 7 Series/C216 Chipset Family USB Enhanced Host Controller #1 [8086:1e26] (rev 04)
Make a note of the sequence which is highlighted in bold. The above example is: 8086:1e31 and then type the following command as root. If you do not see an EHCI controller (sometimes listed as an 'Enhanced Host Controller' as in the example above) listed then this procedure will not work.
- setpci -H1 -d 8086:1e31 d0.l=0
This change will only last until the system is rebooted and so the procedure will have to be repeated each time. Once you have obtained the controller information you only need to type the setpci command. For convenience, this command can be entered into a script and then the script can be run to invoke the change when required.
Important Note: Ubuntu Unity Users
Please note, if you are using Ubuntu Unity then you will need to download the following archive. Once downloaded, extract the archive and copy 'libgtk-x11-2.0.so.0' into '/usr/local/AstroDMx_Capture/lib'. This is required because there is an issue with Ubuntu Unity and without this file the UI will not render correctly. Once this is implemented the AstroDMx Capture UI will render with a generic theme instead of the operating system's theme.
This is not required for any other operating system, including other flavours of Ubuntu.
Important Note: ZWO USB2 Cameras
In order for USB2 ZWO cameras to work, one of two things must be done. The ZWO manufacturer recommends that the camera firmware should be flashed with their compatible firmware. The compatible firmware can be download directly from the manufacturer by clicking the link below. However, doing this causes issues with 16-bit long exposure (greater than 1 second). There is a second option, which does not require the camera to be re-flashed. This involves patching the Linux kernel. More information and instructions will be added to this site in due course. The second option does not suffer from the long exposure issue.
ZWO also have a Windows flashing tool which can be downloaded from the downloads section of the ZWO website.
