Setting The Magnitude Limit - Celestron NexStar 90 MAK Instruction Manual

names of the brighter stars and constellations, you
should set the magnitude filter in TheSkyX to
Second or Third magnitude. That way, when you
go out at night to compare what you see on your
computer to what you can see in the real sky, you
won't be confused by a screen display that shows
more stars than you can actually see from your
location.

Setting the Magnitude Limit

This command tells TheSkyX to only display stars
brighter than a selected magnitude.
1. Choose the Chart Elements tab from the
Display menu, or click this tab on the Command
Center Window.
2. Highlight the Celestial Objects text by clicking
on it.
3. Click the Show Attributes button.
4. Near the middle of the Chart Elements tab
you'll see a button labeled Magnitude Limits.
You can enter a value between 30.0 and -6.0, or
change the magnitude using the slider.
Note: you may need to stretch the Chart
Elements window to access the slider. You can
adjust the size of a dialog box by moving the cursor
to the edge of the box, then clicking and dragging it
to the desired size. You can also move the box
anywhere on the screen.
Notice as you move the slider how the number of
stars on the Sky Chart changes to reflect the
changing magnitude limit.
