of the noise. It’s slightly slower when using dark frames so only
use this when you need to.
Update Mode
– Sometimes you want to tweak the focus, look at an image,
tweak it again, etc. Setting this to
Manual
causes the Focus mode
to pause between images until the
Space Bar
is hit or you click the
Pause/Resume
button.
Peak
– This shows the position and brightness of the brightest pixel in the
Focus mode image. We’ll use this later to get the best focus by
maximizing the
Peak
on a
star
.
Pause/Resume
– Click this button at any time to pause or resume the focus
mode. This can be handy for going back and forth between the
telescope and the computer or for studying the images.
You can read more about the other items in the
Help
but we now know
enough for basic operation. Exit
Focus Mode
by closing the
Focus Mode
dialog or closing the image window.
You’ve come a long way in this brief tutorial. If you want to spend
some time reading the
Help
file or the
CCDOPs Manual
, which is included
on the CD-ROM that would be useful. Otherwise it’s time for trying it out
at the telescope.
