Which One's the Alignment Star?
If you're not familiar with objects in the night sky, how can you be sure if the star
in your eyepiece is really the alignment star?
The rule of thumb is that an alignment star is usually the brightest star in that
area of the sky. If you perform a GO TO to an alignment star and you're not sure
if you have located the alignment star or it isn't in the eyepiece, look through your
viewfinder. When you view an alignment star in the viewfinder, it stands out
dramatically from the rest of the stars in that portion of the sky. The viewfinder
will help you locate a star more quickly than the eyepiece. Using AutoStar, set the
slew speed to 6 (press Number key 6) or higher and use the Arrow keys to
center the alignment star in the viewfinder or the SmartFinder. If your viewfinder
and SmartFinder have been aligned with the telescope, the alignment star
should now be in the eyepiece. Set the slew speed to 4 or less and center the
star in the eyepiece. Also see the SPIRAL SEARCH
