the display update more rapidly. Click on the Loop button and then
on the Expose button. This will start an exposure that will repeat
until the Loop button is pressed again. Adjust your telescope focus
until the star image is sharp, rather than a large circle.
Artemis Capture offers a simple tool
to help you find the best focus. To
activate it, simply double-click on a
star, and the Star Tracking window
will pop up, showing the bright-
ness level and FWHM of the star.
Best focus is the point at which the
FWHM is smallest and the bright-
ness level is highest. Keep in mind
that this feature works best when
the image is not saturated, so if the star has a brightness level
approaching 5000, you should either shorten your exposures or
select a fainter star.
Display Options Window
This window allows you to adjust the way
in which the -bit image is mapped to the
PC’s display. Basically, it compresses the
5000 brightness levels into a range which
can be displayed on a computer monitor.
Always keep in mind that the settings in this
window only affect the way the image is dis-
played, not the data in the image itself.
Hint:
Use the reticle function to assist with
centring the reference stars of your Go-To mount.
