For example, GoQat supports QSI and Starlight Xpress filter wheels. INDI supports many wheels. RS232 / USB converters. Most of them are handled by Linux, a list has to be done. Linux kernel sources links: documentation on usb serial devices and drivers and list of files in drivers/usb/serial (= list of chipset names). USB video grabbers.
- This driver was not written by, authorized by, sanctioned by, or any thing else by Starlight Xpress (SX). It was independently developed from the developer documentation and sample code available from the SX website. Terry Platt of Starlight Xpress is aware of the effort, and has provided me with some missing bits of developer documentation.
- The SX driver is found in ‘Device Manager’ and is separate from the MaximDL plug-in 5.29 that you refer to. If you plug in the camera and look at the details of the Universal Serial Bus device ‘Starlight Xpress CCD’, you will see the Driver under one of the tabs.
- The new code then restarts the chip and it now identifies itself as a 'Starlight Xpress USB2.0 camera driver'. This driver has a 'VID' (Vendor identifier) of 1278 (Starlight Xpress Ltd) and a 'PID' (Product identifier) which depends on the camera type - the SXV-H9 has a PID of 0119.

The Slim Lodestar or Ultrastar USB CCD Option
NeutronOptics x-ray or neutron cameras can be supplied with an optional slim CCD unit, with either 752x580 (lodestar) or 1392x1040 (ultrastar) pixels. The slim CCD has far higher 16-bit intensity resolution compared to only 8-bits from the original 'video' CCD. This CCD unit cannot be Peltier cooled, and is connected to a Windows computer via a single USB-2 cable used both to control the camera and collect the image. Amplified 10m cable extensions can be supplied.The mini i-Cam is the simplest form of this camera. The following instructions apply, but first remove the O-ring holding the carbon window and scintillators to check the focus of the camera using the focusing grid with ambient light. Select one scintillator and cover it with the C-window and O-ring. Thinner scintillators give higher resolution but lower intensity: the neutron scintillator is yellow.With the 580x752 pixel CCD (8.6µ pixels) a 310µ grid can be imaged over a 35mm diameter to a pixel resolution of 50µ (x8 detail). Observed resolution will depend on the scintillator.

Install the Camera Driver
- Browse the CD and install the Starlight Xpress drivers for a 32-bit or 64-bit system
- Connect camera to a USB port. If the driver is not found automatically:
- Click Windows 'Start' and open 'Devices and Printers'
- Double-click 'Unknown Device', select 'Hardware', 'Properties'
- Click 'Change Settings' under the 'General' tab
- Click 'Update Driver' under the new 'General' tab
- Cancel the preliminary search on Windows Update - it's not there
- Choose 'Browse for Drivers' within the directory you downloaded
- Select the 32-bit or 64-bit driver folder within that directory
- Click 'OK', 'Next' then accept to install the driver
- The Windows Device Manager should now show a Starlight Xpress CCD
- If you use the 10m amplified USB extension, first plug it in without the camera.
ImageJ-for-ASCOM is best for the most sensitive acquisitions, but first try these.
Simple Real-time Imaging with the Slim USB Camera
If you just want to see your sample in the beam, with cyclic exposures of from 0.05s to 512s, you can install this simple free application for which you just click the Loop/Stop buttons after selecting the camera. The 16-bit image is updated in real time, and you can save it thenopen it with ImageJ to remove noisy pixels and enhance it in other ways.- Download and install the free PHD Guiding application.
- Download our custom PHD.exe to overwrite PHD.exe in the PHDGuiding folder.
- Launch our custom PHD.exe to display the image and controls.
- For Macintosh systems, just use the standard OSX PHD Guiding application.
- Click the image opposite to enlarge it
- Click the camera icon and select the LodeStar/UltraStar CCD camera
- Click the LOOP icon to start exposing for the selected time
- Click STOP to stop the loop at the end of the current acquisition (wait for it)
- File/Save Image saves the 16-bit image
- The slider changes display contrast
- Try the 3x3 median Noise filter
- Try Take Dark background subtraction
- Open the saved images using ImageJ
The PHD display is 752x580 pixels, full size for the LodeStar, ~half size for the UltraStar.
Use the ASCOM driver for sharper images, better noise reduction, and hardware binning, which will increase intensity at the expense of resolution. You should first install the ASCOM Platform 6 environment. The ASCOM driver is installed in C:Program FilesCommon FilesASCOMCamera and you can use Control Panel/Programs or the ASCOM Profile Explorer to remove it.
In the ASCOM camera chooser, select 'Starlight Xpress Lodestar Guider' (or 'Ultrastar'), click on 'Properties' and un-select all options. Click on 'Noise' to filter out hot pixels (see Hints below).
Starlight Live Image Capture with the Slim USB Camera
Starlight Live automatically collects a series of images, and can sum them in real time.The 16-bit images can be opened with ImageJ to remove noisy pixels and de-interlace.
- Download and install the free Starlight Live camera capture application
- For Macintosh systems, use the OSX version of Starlight Live
- Launch Starlight Live to automatically connect to the Lodestar/Ultrastar camera.
- The Exposure Control tab enters the Exposure in Seconds
The Green/Red buttons Start/Stop a series of images. Arrow button resets - The Stacking tab sums the images live
Set Max Pixel Displacement = 0 (this is useful only for astronomical imaging)
Set Filter to Median 3x3 to filter out noise (or filter noise later with imageJ). - In the Display tab bracket the intensity between the Dark and White Levels).
- The Image Export tab is used to save FITS images
SharpCap 3.2 Camera Control and Acquisition
SharpCap 3.2 was also designed for amateur astronomers, and contains additional features that you will not need for x-ray or neutron imaging. Download the 32-bit version of SharpCap. The camera will be automatically recognised if it is plugged in, and you just need to choose it from the “Cameras” menu. A window will open with the image and camera controls on the right. You can arrange the order of controls by dragging the 3-line icon. (Click the image to enlarge it).In the 'Camera Controls' you can set the Exposure (toggle LX mode for long exposures), the Gain (higher gains also increase noise) and you can read the sensor temperature. In the 'Capture Format', select TIFF or FITS and Mono16. To speed up readout, select a reduced 'Capture Area', and drag the rectangle to the Region of Interest. You can also drag the vertical line in the 'Display Histogram' to stretch the intensity display.
Stacking short exposures in SharpCap 3.2
An important advantage of SharpCap is real-time stacking of a series of short exposures, which allows you to judge when you have accumulated sufficient intensity. Click on the 'Live Stack' icon above the image display to open this stacking window. You can drag this window so that it does not cover the image. Switch off
'Align Frames' which refers to alignment based on stars. Most of the controls to the right are also for astronomers; only the live histogram is useful, but normally you would save the summed stack as a 32-bit image and filter noise from it with imageJ. You can also use imageJ to stack a series of short exposures, which allows filtering of noise from the individual images before averaging. For very short exposures this may be better than averaging first and then filtering. Use the SharpCap menu Capture/Start_Capture then enter the number of images to be saved. After capturing those images, use the ImageJ menu File/Import/Image_Sequence, open the first image, and then OK to import all images in that directory into a displayed stack. Use Image/Adjust/Brightness-Contrast to examine the noise, and apply Process/Noise/De-speckle to all images. You may need to De-speckle twice. Finally sum or average the stack using Image/Stacks/Z-Projection.
ASCOM Camera Control and Treatment with ImageJ
ImageJ is recommended for image analysis. ImageJ will open the raw FITS files, then remove noise, modify contrast and other properties, and save them in various formats. More importantly, it will allow you to measure intensity profiles and display your data in ways that will make it more meaningful.
If you install the ASCOM Platform 6 environment, and the sxASCOM camera driver, you can control the camera directly using ImageJ for ASCOM. This has advantages in that sequentially acquired images, eg for tomography, are opened directly in ImageJ.
You can even simultaneously aquire images from two cameras and stitch them together.
When installing the sxASCOM camera driver,choose to install a 'Starlight Xpress Standalone Guide Camera', then choose a 'Starlight Xpress LodeStar Guide Camera' (or 'Ultrastar'). There is no need to install ASCOM drivers for the other cameras.
After choosing the 'Starlight Xpress LodeStar/Ultrastar Guider' in the ASCOM chooser, click 'Properties' and unselect every option, but choose 'Double Exposure Short'.
Hints on getting Optimal Images
- The center of the image doesn't correspond to the centre of the window
because the CCD chip is not centred to better than 0.5mm in its housing - The exposure time depends of course on the intensity of your beam
- 2x2 binning will give x4 the intensity and faster readout, but halve resolution
- Use the 'Process/Noise/De-speckle' filter in ImageJ to remove noisy pixels
- The slim Lodestar CCD (not Ultrastar) is interlaced to obtain very fast readout
- If this appears to be a problem, try the ImageJ de-interlace filter
- Copy the de-interlace filterDeinterlace_.class to ImageJplugins & apply it
- But de-speckle the raw image first, before de-interlacing or bluring
- 'Gaussian blur' from Options/Execute makes it difficult to remove noisy pixels
- To correct for barrel distortion install the ImageJ Barrel Distortion macro tool
Latest Drivers
#110219 I’m curious about the latest drivers. One issue I have had that I have actually seen that surprised me was when I was using ACP/MaxIm and doing a ACP Expert run. If I remember correctly the run had just started and was beginning to start on targets. There will be a pointing image where the main imager takes a short image, plate solves and makes sure it’s on target and the PA is correct for the rotator. At this point it would center as needed and take a guider image and then determine the best star to guide on. But what was happening is the guider image was taken and immediately it would disappear and the program would indicate there were no guide stars visible in the frame when in fact there had been but now the image is closed. And it would repeat this until it was manually interrupted by aborting that operation causing many failures should no one actually see this happening. What I did was disconnect the guide camera and the reconnect and it imaged fine for the rest of the night. It was the only time I had seen this but have no idea what actually caused the issue. It may have happened when I was asleep in other runs where I had multiple failures but can’t say for sure. So in a very long way around, how do I determine the driver version I have installed. In MaxImDl it says I have SX Universal 5.29 but I really have no idea what the latest driver is. Where or what should I be doing to stay up to date. My system controlling the observatory is a Windows 10 Pro 64 bit OS. I have been running this system since 4/20/20 and it has/is running very well short of this instance that I am aware of. Suggestions? Thanks, Steve |

#110228 Generally speaking, just updating the driver will work, but Windows may object to loading an older driver over the new one. If you hit a problem, go the the Windows Control Panel and select ‘Software and Features’. You will find the current driver at the bottom of the list under ‘Windows Driver Package’ and you can get Windows to uninstall it.
