LX90 TIPS

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 tip, page 20.
