After the exposure and download have completed (about 4 seconds) an image of
some kind will appear on the computer monitor. It will probably be poorly focused
and incorrectly exposed, but any sort of image is good. In the case of the pinhole, all
that you can experiment with is the exposure time, but a camera lens can be
adjusted for good focus and so you might want to try this to judge the high image
quality that it is possible to achieve.
Various other exposure options are available, as can be seen in the picture above.
For example, you can ‘Bin’ the download by 2x2, or more, to achieve greater
sensitivity and faster download, or enable ‘Continuous’ to see a steady stream of
images. The Histogram plot allows you to see the status of the image brightness
distribution and you can adjust the sliders to optimise your view.
If you cannot record any kind of image, please check the following points:
1)
Ensure that the power indicator lamp is on and that the cables are properly home
in their sockets.
2)
If the screen is completely white, the camera may be greatly overexposed. Try a
shorter exposure time, or stop down your lens. See if covering the lens causes the
image to darken.
3)
If the USB did not initialise properly, the camera start-up screen will tell you that
the connection is defective. Try switching off the power supply and unplugging
the USB cable. Now turn the power supply on and plug in the USB cable. This will
re-load the USB software and may fix the problem after restarting Starlight
Vision. Otherwise, check the device driver status, as previously described, and re-
install any drivers which appear to be defective.
4)
If you cannot find any way of making the camera work, please try using it with
another computer. This will confirm that the camera is OK, or faulty, and you can
then decide how to proceed. Our guarantee ensures that any electrical faults are
corrected quickly and at no cost to the customer.
Image enhancements:
The current version of Starlight Vision does not include any enhancement functions,
but these will be added to later versions (available from
www.sxccd.com
). Further
image processing can be done by saving your raw images as FITS files and exporting
them to third party software. PixInsight is a powerful processing software, but there
are many others available. AstroArt, MaximDL, Nebulosity etc.
Your first image may be satisfactory, but it is unlikely to be as clear and sharp as it
could be. Improved focusing and exposure selection may correct these
shortcomings, and you may like to try them before applying any image enhancement
with software.
