AstroDMx Capture - Changelog

Changelog Version:

  • Added: A button to automatically scale the preview display to the minimum and brightest pixel values coming from the camera in realtime. This function should help to brighten the preview screen for dim objects but depending upon the exposure value, this setting might not make any visible changes and for very short exposures, this function could show apparent noise which will not be in the saved data. This option can be found in the "Display Controls" area. This was the default setting in previous versions of AstroDMx Capture.

  • Bug fixes and optimisations

Changelog Version: 0.88.2

  • Added: Capture profiles (all camera parameters can be saved except cooling and histogram configuration). The new capture profile functionality can be found at the very top of the camera controls that are located on the right-hand side of the main UI.
  • Added: Font size function (Small (default), medium, large, largest). This allows the user to specify a font size that is appropriate to their eyes or screen resolution. The font size functionality can be found in the Options drop-down menu.
  • Added: Exposure cancellation button. This function allows for convenient cancellation of the currently running long exposure. The exposure cancel button only shows for cameras operating with exposures greater than 1000ms.
  • Added: Option to show camera units (either percentages or camera native). This is represented in the text box to the right of the sliders, in the capture log and metadata. This feature should help migrating from other capture applications. The units mode can be changed from the Options drop-down menu.
  • Start and end capture times in the capture log are now zero padded (example: previously, if the date was 3 January 2021 the date would have been written 2021/1/3, it is now written 2021/01/03. Times work in a similar way. Example, the time midnight is now written 00:00:00 instead of 0:0:0.
  • Fixed: Off-by-one for capture time displayed in the log.
  • Fixed: Atik binning bug.
  • Updated: QHY SDK to version 2021/3/13.

  • Updated: libgphoto SDK to version 1.17.
  • Updated: ZWO Filterwheel SDK to version 1.6.
  • Bug fixes and other improvements.

Changelog Version: 0.86.3

  • Added: Experimental support for the Raspberry HQ PiCamera. Currently, only an RGB pixel format has been implemented and there are limited resolutions with limited frame rates. Additional functionality and optimisations are pending implementation, however, the Raspberry Pi Camera has a low priority. The Raspberry PI camera is only implemented for the 32-bit Raspberry Pi build and requires the official Raspberry Pi OS.
  • Added: Automated version checking at startup. This functionality automatically checks for new versions at startup and silently fails if there's no Internet connection. The automatic version checking can be disabled if required, if disabled, the user can still check manually by clicking on the "Check for New Version" button located in the Controls: MISC area or via the "Help" drop-down menu.
  • Added: An "Expose Now" button. If the exposure delay functionality is activated, then pressing this button will force the camera to take one single exposure. In this configuration, if the Snapshot button is pressed, then AstroDMx Capture will save whatever is currently seen on the preview screen. The Exposure delay functionality is located in the "Controls: Exposure" group.
  • Changes to the Snapshot functionality. If the Exposure delay functionality is active, then pressing the Snapshot button will save whatever can be seen on the preview screen. This functionality is located in the "Controls: Exposure" group.
  • Improvements to the 16-bit brightness control.
  • Default changes: The application now defaults to full-screen but it is still possible to set the UI size to whatever is appropriate to the user.
  • Default changes: The size of the control area is no longer saved on exit. This default can be changed in the "Options" drop down menu.
  • Renamed some DSLR UI components for more more clarity
  • Bug fixes and other optimisations.

Changelog Version: 0.86.2

  • Faulty version has been deleted

Changelog Version: 0.84.9

  • Fixed various issues associated with DSLR cameras.
  • Fixed various data races associated with the Connection Monitor.
  • Added: Option to change the mode of QHY cameras. The two options are "Video" and "Frame". Video mode is the default and should be used most of the time as it provides faster frame rates. The Frame mode is optional and should only be used for long exposure. The new option is located in the exposure group.
  • Other bug fixes and improvements.

Changelog Version: 0.84.7

  • Added: Full support for the SVBONY SV305 and SV305PRO for macOS.
  • Added: Functions to delay camera exposure or stop exposing entirely. The new function can be found in the 'Exposure Controls" group.
  • Added: Additional messages that aid the most optimal setup. For example, AstroDMx now warns the user that RGB24 is an 8-bit pixel format and also warns when attempting to save undebayered data. All these warnings can be disabled if required.
  • Added: 16-bit non-destructive incremental brightness control that can be used with any of the 16-bit transforms. This control is to facilitate the visualisation of 16-bit image data as they are captured, but being non-destructive, does not affect the data that are saved.
  • Significant changes to the debugging mode. Previously, the debugging mode was invoked by a special launcher icon but in this version, the debugging mode is activated by a toggle switch located in the Options drop-down menu. Activating debugging will output a detailed log file which is stored in the output directory. This debugging log can help the software developer to fix problems that might be experienced. On Linux, It is still possible to redirect the debugging output to the console by passing the -D1 (for colour) or -D2 (for non colour) switches from the terminal.
  • AstroDMx Capture is no longer distrusted with separate installers for specific CPU Microarchitectures. In this version, the distributions install builds for the Haswell and Core2 Microarchitectures a well as a generic build that should run on any 64-bit CPU regardless of age. There is a special loader program which interrogates the CPU and then runs the build that is most appropriate for your CPU. This functionality is not currently implemented for macOS, macOS is only distrusted for Core2 CPUs and above.
  • AstroDMx is now linked against glibc-2.30, glibc-2.17 for x86-64 Linux and 2.28 for the Raspberry Pi.
  • All builds of AstroDMx Capture are now compiled with gcc 10.2.
  • The manual installers for Linux now contain a script to install the application.
  • On Linux, AstroDMx Capture can now be run from any directory.
  • Stopped strange V4L2 (Video 4 Linux) devices from showing on the Raspberry Pi4.
  • Fixed: DSLR timeout related to changing the Capture Target setting.
  • Fixed: x3 binning for ZWO cameras.
  • General bug fixes and other optimisations.

Changelog Version: 0.82.2

  • This version fixes a bug associated with capturing long exposures that affected all builds.
  • The CORE2 build no longer blocks the application from running if the checks detect that the CPU might be too old. If my CPU checks discover that the CPU is too old, the application gives a warning but allows execution. If the CPU is really too old, then the application could throw a SIGILL message and then terminate.

Changelog Version: 0.82.1

  • Linux x86-64 binaries now target two CPU microarchitecture. The first targets the Haswell microarchitecture and requires a CPU manufactured from 2013 and the second targets the Core2 microarchitecture (CPUs manufactured from 2006 onwards). If one attempt to run the Haswell build on an old CPU the software will tell the user to download the Core2 build. This concept allows AstroDMx Capture to take advantage of advanced vector extensions available in modern CPUs without compromising the ability of AstroDMx Capture to run on older CPUs.
  • Added: Initial Windows Release
  • Added: ZWO & QHY cooling
  • Added: One touch gain (if supported by camera)

  • Added: Additional predefined and custom FITS metadata
  • Added: FITS to the Snapshot mode
  • Added: ROWORDER to FITS metadata
  • Added: ATIK Artemis SDK support (this is in addition to the Cloudmakers SDK)
  • Added: libuvc support for Linux. libuvc is an alternative to Video4Linux but requires a udev rule rule to be setup. libuvc is hidden in the capture dialog by default. Uncheck "Don't show libuvc devices" to use this function. libuvc is the default for UVC cameras on macOS.

Changelog Version: 0.68.1

  • Added Adaptive Homogeneity-Directed (AHD) Debayering Algorithm. More Information

    Added Adaptive Homogeneity-Directed (AHD) Debayering Algorithm. Less Information

    AHD is a very high quality debayering algorithm which is computationally heavy and so it should only be used for long exposures and is not recommended for use with the Raspberry Pi

  • Exposure values can now be typed for improved selection precision. More Information

    Exposure values can now be typed for improved selection precision. Less Information

    Exposure values are entered by typing a number followed by ms for milliseconds, s for seconds and m for minutes. The following shows a few examples:

    150ms = 150 milliseconds.
    5s = 5 seconds.
    1m5s = 1 minute and 5 seconds.
    75s = 1 minute and 15 seconds.
    3000ms = 3 seconds.

    For more information see the AstroDMx Capture Overview page.

  • SVBony SV305 one touch white balance function
  • SVBony SV305 Map to Upper function. More Information

    SVBony SV305 Map to Upper function. Less Information

    By default data comes off the SVBony SV305 camera in the lower part of 16-bit, this causes initially dark images which need to be stretched in order to see the detail. The 'Map to Upper' function shifts the data into the upper
    part of 16-bit which produces initially brighter images.

  • Added an 8-bit monochrome output format for the SV305
  • The installers for AstroDMx Capture now create a new menu category called "AstroImaging" and the software launchers are placed into this category. Depending upon your specific distribution, the software categories might not be
  • Bug fixes

Changelog Version: 0.66.2

  • 0.66.1 has been removed due to an issue with the QHY SDK.
  • Full support for the SVBony SV305 camera (64bit Linux Only. There's currently no support for the SV305 on the raspberry PI due to no SDK.)

  • Frame rate has been moved to the bottom of the main UI

  • Changes the ROI Nudge function More Information

    Changes the ROI Nudge function Less Information

    The Region of Interest nudge function allows the user to use the cursor keys to move the ROI position. This function is useful if the object of interest is drifting during capture..

    The ROI nudge button can be found on the top controls. When clicked it changes to red and when it loses focus, the colour changes back to the default colour. If the button is red, then the cursor keys can be used to nudge the
    ROI position.

  • Added an estimated time to completion function for long exposures. This information is shown in the status bar (at the bottom of the main UI) and also shows in the capture window. This function only works in "Frame Limit" mode.
  • Improvements and bug fixes for the QHY5L-II-C and QHY5L-II-M cameras
  • Bug fixes

Changelog Version: 0.64.4

  • Fixed a bug associated with cancelling ZWO long exposures

  • Fixed QHY long exposure bug More Information

    Fixed QHY long exposure bug Less Information

    The QHY SDK version 6.0.5 has a bug which causes long exposures to fail for the QHY5L-II-C and QHY5L-II-M. In order to fix this, the SDK has been dropped to 5.10.0.

  • Deleted version 0.64.3

Changelog Version: 0.64.1

  • Added DSLR camera support More Information

    Added DSLR camera support Less Information

    The new DSLR tethering support has been tested on the Nikon D50, Nikon D5100, Canon 4000D, Canon 600D and the Canon 40D. Bulb mode should work on all Canon cameras but many Nikon cameras do not support tethered bulb. Many
    other DSLR cameras should work. The developer of AstroDMx would like to hear from anybody that has successfully used a DSLR camera not detailed here.

  • Significant performance optimisations More Information

    Significant performance optimisations Less Information

    Performance critical sections of AstroDMx have been completely rewritten to make better use of multithreaded CPUs. Fast computers will most likely not see any improvement because they are already capable of running a specific
    camera to the manufactures theoretical maximums. Slower or older computers should see significant frame rate improvements on high megapixel cameras. The display controls no longer impact frame rates and there are options to
    lower the resolution of the preview screen to speed up processing further.

  • Added display performance options More Information

    Added display performance options Less Information

    Processing data for the live preview can be computationally heavy for high megapixel cameras. The preview screen performance options drop the resolution of the live preview without affecting saved data. Dropping the resolution
    of the preview screen can greatly increase the speed at which the live preview screen updates.

  • Significant preview display improvements More Information

    Significant preview display improvements Less Information

    The preview display code has been completely rewritten to take advantage of multithreaded CPUs.

  • Added hardware accelerated preview display mode More Information

    Added hardware accelerated preview display mode Less Information

    The preview display now operates in one of two modes. The first is the original mode (software acceleration) and a new mode which uses hardware acceleration via OpenGL. Hardware acceleration should be more efficient on
    computers with high-end GPUs and use less CPU time. The mode can be changed from the drop-down menus and software acceleration is the default option.

  • Mouse to pan around the preview display (OpenGL mode) More Information

    Mouse to pan around the preview display (OpenGL mode) Less Information

    If the preview display scale is larger than the screen size one must pan around the area. In software acceleration mode, the application presents scroll bars for the purpose. However, in hardware acceleration mode, one must
    use the mouse to pan around the image area by grabbing somewhere the image. There are four panning speeds which can be changed from the drop-down menus.

  • UI Tweaks and optimisations
  • Camera controls, such as gain or gamma, can now be made during long exposures without cancelling the previous control
  • Values can now be typed into the display control UI
  • Significant improvements to the way that the application stores settings More Information

    Significant improvements to the way that the application stores settings Less Information

    As of version 0.64.1, AstroDMx stores its settings in a highly structured way which means that the application will maintain its user supplied settings after upgrades.

  • The main camera controls can now be hidden More Information

    The main camera controls can now be hidden Less Information

    To allow more area for the preview display, it is now possible to hide or show the main controls. This can be a huge benefit if using a small or low resolution monitor. The show/hide control can be found on the top control bar
    of AstroDMx Capture.

  • Improvements for failed exposures handling
  • Saturation and Reticle colours are now stored
  • Display controls / transforms no longer have an affect frame rates
  • Added auto USB bandwidth and USB speed functions for ZWO cameras
  • Fixed possible font issues on some Linux distributions
  • The main control area size now stored
  • Added SER time stamps
  • Added mouse over help to many UI controls
  • Improved function to scale the live preview
  • Saturation and reticle and now be changed in realtime
  • Colour space and resolution can now be changed during long exposures More Information

    Colour space and resolution can now be changed during long exposures Less Information

    Previous versions of AstroDMx Capture did not allow the user to change the camera's resolution or the colour space control without dropping the exposure to below 1000ms. As of version 0.64.1, these values can be changed.
    Changing the resolution or colour space setting will cause the current exposure to be cancelled. If the connected camera does not support exposure cancellation then a message is presented to the user and the request is

  • Fixed a problem that sometimes caused the main controls to jump position
  • QHY SDK updated to version 5.1.0
  • ZWO SDK updated to version 1.14.0715
  • Many other bug fixes and improvements
  • Temporarily removed the reset all controls reset function

Changelog Version: 0.50.11

  • Fixed Map to Greyscale crash
  • Fixed Atik Binning problem
  • Fixed Atik Crash on exit

Changelog Version: 0.50.9

  • Added a lag control function More Information

    Added a lag control function Less Information

    Some Video4Linux (UVC) cameras can show image lag despite a reasonable frame rate. For example, a connected camera could be showing a frame rate of 15 fps but, if the camera was moved, it could take a few seconds for this
    movement to be observed on the preview screen. Frame lag control is available in the main options menu.

  • Fixed problem with the AstroDMx_DATA directory not been created and showing lots of errors
  • Improved error handling for writing output files
  • Reduced CPU usage for QHY cameras
  • Fixed problem with the histogram using lots of CPU time
  • Other post-release bug fixes and improvements

Changelog Version: 0.50.4

  • Realtime calibration now works for frame integration
  • Bug fixes

Changelog Version: 0.50.1

  • Full support for the Atik 314L
  • Full support for the Atik 314E
  • Full support for the Atik 320E (Colour)
  • Other 16-bit Atik cameras should work More Information

    Other 16-bit Atik cameras should work Less Information

    Atik cameras with mechanical shutters and SetPoint coolers have been fully implemented but are untested. The developer of AstroDMx would be interested to hear from anybody who has used an Atik camera not listed above.

  • Improved support for the ZWO ASI178MC
  • FITS Support with configurable FITS Metadata
  • Added Non-destructive display controls (Gamma, Contrast and Brightness) More Information

    Added Non-destructive display controls (Gamma, Contrast and Brightness) Less Information

    The display controls feature can be used to change how the stream data are displayed on the preview screen. These controls do not affect the saved data but can slow down the frame rate. If using a slower computer, it is
    advised that the display controls are disabled before starting the main capture routine.

  • Added additional 16-bit to 8-bit display transforms (Linear, Gamma Log and Inverse Hyperbolic Sine) More Information

    Added additional 16-bit to 8-bit display transforms (Linear, Gamma Log and Inverse Hyperbolic Sine) Less Information

    Cameras capable of operating in 16-bit mode must have their data mapped to the 8-bit preview display. Mapping these data linearly does not show faint detail very well. AstroDMx therefore provides three additional methods to
    show the faint detail on the preview screen. Gamma Log, ASinH (Inverse Hyperbolic Sine) and ASinH (ASinH) (inverse Hyperbolic Sine of the inverse Hyperbolic Sine). Gamma Log and the ASinH functions shows fainter information
    but they are computationally heavy and so should only be used for long exposures.

  • Added Endpoint Control More Information

    Added Endpoint Control Less Information

    The endpoint control function is an experimental feature. In order to map a 16-bit stream into the 8-bit preview display, AstroDMx calculates the brightest and dimmest pixels. Sometimes, the brightest and dimmest pixels can be
    skewed by hot or dead pixels. The endpoint control feature therefore trims the brightest and dimmest pixels by a fixed percentage and uses these new values to map the 16-bit stream to the 8-bit display.

  • Added filter wheel exposure ratios More Information

    Added filter wheel exposure ratios Less Information

    Filterwheel ratios allow the user to specify an offset value for each filter which will automatically increase or decrease the exposure length when a specific filter is selected. For example, if the exposure was set at 20
    seconds and the filter offset was set at 1.2 then the exposure would be automatically be increased to 24 seconds. Similarly, if an exposure was set at 25 seconds with an offset of 0.8 then the exposure would automatically be
    changed to 20 seconds. Filter ratios are available online for many filter sets or can be calculated using data from your own experience.

  • Long exposure indicator now shows hours, minutes and seconds
  • ROI chip position is now shown in the UI
  • Capture window can now be minimised More Information

    Capture window can now be minimised Less Information

    The capture window can now be minimised to increased the amount of available desktop real-estate. Key information, such as number of frames remaining, is displayed on the AstroDMx status bar (at the bottom of the application).
    There are three keyboard shortcuts which can be used to control the capture. C=Capture, P=Pause Capture and S=Stop. These shortcuts work even if the Capture window does not have focus.

  • Added Keyboard shortcuts More Information

    Added Keyboard shortcuts Less Information

    Many parts of the UI now have shortcuts. Pressing the CTRL key will show the available shortcuts with an underscore. Additionally, the Capture Window has the following shortcuts C=Start Capture, P=Pause Capture and S=Stop. The
    Capture Window shortcuts work even if the Capture Window does not have focus.

  • Significant improvements to the realtime calibration system More Information

    Significant improvements to the realtime calibration system Less Information

    The calibration system has a non-destructive mode which applies only to the preview display. This function is useful for cameras, such as the ASI120MC, which can have lots of hot pixels when being used for long exposure. The
    calibration system can, for example, be used to remove these hot-pixels without affecting the saved data. The histogram can also be dark frame corrected without affecting the saved data which yields a more accurate
    representation of the incoming signal.

  • Calibration frames can now be saved in the FITS file format.
  • The Heartbeat function has been renamed to Connection Manager More Information

    The Heartbeat function has been renamed to Connection Manager Less Information

    The connection monitor watches the connected camera. If it goes offline then it will be automatically reinitialised and the operations will continue from the point of failure. For example, if the user is capturing data and
    accidentally knocks out the USB cable, AstroDMx will attempt to automatically reinitialise the camera and allow data collection to continue without any user intervention. The timeouts for the connection monitor can be changed
    from the drop-down menus.

  • New UI to control camera timeouts.
  • Added a custom ROI resolution UI.
  • Added function to make AstroDMx startup at the size it was when closed More Information

    Added function to make AstroDMx startup at the size it was when closed Less Information

    AstroDMx will now automatically startup at the size it was when it was last closed down. This function can be disabled in the drop-down options menu.
