StarlightLive V3.2 Released

Recommended Posts

Hi All,

StarlightLive V3.2 is now available to download from the SX website:

OSX version

Windows version

Bug fixes and some minor new features. Change log as follows:

- Renamed command line argument 'force-sx-vid' to '-force-sx-vid' for consistency with other command line arguments.
- Renamed command line argument 'force-sx-pid' to '-add-sx-vid' for clarity of the command line argument functionality.
- Added new command line argument '-exclusive-sx-pid' which allows the user to force the application to only connect to the SX camera with the matching PID. All other cameras will be ignored.
- Added FWHM limit to stacking options. Setting 'Max FWHM' to 0.0 disables this feature, otherwise if for a given exposure the mean FWHM exceeds the value specified on the user interface the exposure is dropped and not added to the current live stack.
- Added automatic dropping of an exposure if the mean alignment error exceeds 1.0 pixels as this typically means the alignment algorithm has failed to reach a sufficient solution.
- Updated QT application framework to version 5.7 for latest feature and bug fixes. For the Windows version, this has forced an update in development tool chain (Visual Studio 2015) therefore the latest Visual C++ redistributable may be required to run the application. This is available from the Microsoft web site at the following URL: https://www.microsoft.com/en-gb/download/details.aspx?id=48145
- Fixed Bug: Issues with text edit boxes on image export tab.
- Fixed Bug: Camera exposure timer was not restarted when no exposure buffers are available.


Windows users  - PLEASE NOTE - as above you will most likely need to download and install the VS2015 x86 re-distributables from Microsoft otherwise the application will not run.


As always I hope the application helps explore the magnificent skies and have fun :-)

As ever, thanks for this new release, which I look forward to trying soon. Coming up to 3 years using your software, I really appreciate the time and effort you put in!

Fantastic, thanks Paul, look forward to trying the FWHM feature. :)

Thank you Paul! Thanks to your continued efforts, StarlightLive has been the model for near real-time astronomy applications. Other software makers follow your leadership and users of their cameras envy the features and ease of use of StarlightLive.

One of the very useful new features is to run multiple instances of StalightLive simultaneously on the same computer, each connected to a different camera. Since I am a very poor typist, especially in the dark, I made Windows shortcuts for each of my cameras to launch StarlightLive and connect to one or the other specific camera.  For those, who want to use this feature, here are the command lines for three most commonly used cameras.

Lodestar:      <path>\StarlightLive.exe -exclusive-sx-pid 0x0507

Ultrastar:      <path>\StarlightLive.exe -exclusive-sx-pid 0x0505

SX-825:       <path>\StarlightLive.exe -exclusive-sx-pid 0x0189

When using multiple cameras simultaneously, the cameras have to be different models. As far as I know, mono and color versions of the same type of camera have the same product ID's and hence cannot be launched simultaneously using this method.

Clear Skies!  --Dom

Thanks Paul for all your hard work. I'll give 3.2 a go next time out.

Hi Paul

Thank you for all your efforts - you really have made EAA a joy for me, cannot wait to get out and try this version.

Thanks Paul.  I am looking forward to having my Lodestar X2 and Ultrastar running simultaneously.

Has anyone managed to use Starlight Live with the older sx cameras? In particular a MX716 connected through the USB2 interface, thus making it equivalent to an SXV7. Starlight Live shows no camera connected. I can use the camera with the old MX7c software by telling the software to ignore PID. (It's now a colour camera as the ccd was exchanged some years ago!) Device manager shows the camera installed correctly.

I'm using a Windows 7 pro laptop.

      Hello everyone!  
      After a pretty dreary September and part of October, I was finally able to get out with students to do some viewing.  Here are some of the objects viewed over two nights using Starlight Live software on my Borg 77edii (f/4) and Borg 125SD (f/5) with a Trius 694 mono camera.  In most cases an IDAS NB-1 "nebula" filter was employed to help with the suburban light pollution in our skies.  The first night (mainly 125SD) was much steadier and drier, but along the coast we take what we can get when it isn't raining!  ;-D
      It's so much fun to see these objects from less-than-optimal skies... I often intend to quit much earlier, only to find myself saying (over and over!) "... oh, look, <object> is coming up... I should just have a look at that before I pack up."  And then another hour goes by!

      Hello, all.
      I acquired an Ultrastar C for EAA last fall. (I only got a few chances to use it over the winter, but we got some desperately needed rain instead. So that's ok.)
      The Ultrastar C has been astounding on the few evenings where the fates have yielded to properly working equipment and clear skies.
      I'm looking for pointers to tools and techniques for post-processing the color FITs image stacks captured from Starlight Live. I'm on a Mac so that limits some of the software options available. 
      The docs for Starlight Live say there is a command line option ('-load-image-rggb') to reload a color FITs file into the program. Does this work from a Mac command line? 
      Are there any other Mac programs that can read the Bayer RGGB color FITs files exported from Starlight Live for manipulation. Or something that can demosaic and export the files for manipulation in Photoshop? Maybe Nebulosity4.

      Hi all,
      StarlightLive V3.3 is now available to download:
      OSX: https://bitbucket.org/Paul81/starlightlive-downloads/downloads/StarlightLive.osx.3.3.zip
      Win32: https://bitbucket.org/Paul81/starlightlive-downloads/downloads/StarlightLive.win32.3.3.zip
      Bug fixes and some feature updates - from the README:
      - Image display processing and stacking performance (speed) enhancements.
      - Added option on the settings tab to select night mode which modifies the user interface to use a subdued dark room theme. A separate option also allows the main image display to be rendered in luminance-red pixel format.
      - Added options on the settings tab to allow the display image to be mirrored horizontally and vertically such that image orientation can be corrected for different optical configurations.
      - Added command line argument '-prepend-title-text <TEXT>' to allow a user specified string to be prepended to the window title bar such that it allows multiple sessions of the application being used concurrently to be easier distinguished.
      - Modified exposures of 1 second or less to be timed via the H/W based timer in the camera as opposed to timed by S/W. This facilitates exposures of 1ms or greater. User interface has been modified to permit minimum exposure time of 1ms which is the smallest permitted by the camera. Exposures of greater than 1 second are stilled timed by S/W such that periodic ping and cooler read-out, in addition to exposure progress bar update still occur. Exposures of less than 250ms on interlaced cameras are no longer at half resolution. Non-binned exposures less than 1 second on interlaced cameras will expose for the required time on the odd field and then the required time on the even field. Therefore the time to take the exposure is double, but the total exposure time for the whole sensor is as requested. This does not apply for binned exposures which complete in the exposure time period.
      - Fixed Bug: Modified histogram processing to help avoid issues when pixels become saturated (either black or white) which caused the display processing to select the wrong peak as the point of which to centre display stretching around.
      - Fixed Bug: Non anti-aliased fonts being selected on some Windows platforms (fuzzy fonts).
