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.
