Tips on Star Alignment
• It is advisable to use fixed stars for the alignments. As the distant stars are
a fixed point of light and they have no area, you can pinpoint a location for
an alignment point. Alignments with the moon, planets, nebulae and star
cluster are not as accurate as star alignment with fixed stars.
• Choosing several alignment stars which are separated over 10 degrees to other will increase the pointing accuracy of your Go-To slewing. Twenty points
are available for the alignment.
• The dialog box on the right appears if the selected star for the alignment is located
within 10 degrees from the previously aligned stars. If you choose OK, the aligned star
less than 10 degrees apart will be deleted and replaced with the latest aligned star.
Choose Cancel if you stop the alignment.
• The dialog box on the right appears if the star alignment is being done with the same star again.
If you choose OK, the star alignment will be overwritten by new one.
Choose Cancel if you stop the alignment.
• If the pointing accuracy of your telescope has not been improved, delete all the alignment stars and align the telescope from the beginning.
• Using stars adjacent to the celestial poles for the star alignment may not contribute to improving the pointing accuracy of your telescope.
• Using stars near the horizon for the star alignment may result in disturbing the pointing accuracy of your telescope as it is affected by atmospheric
conditions.
• Choosing stars from the menu makes your star alignment more accurate than choosing stars from the star chart in CHART MODE.
• If the target is not chosen, alignment will not work.
• Each position of the aligned stars is defined by altitude and azimuth based on a point in time you aligned. Every alignment star moves toward the west
due to the diurnal motion. As a consequence, if the aligned stars move more than 10 degrees (more than 40 minutes in time), the STAR BOOK TEN will
accept the same star for alignment. This is a normal behavior.
• Calculations for star alignment are based on the most reliable two points among the alignment stars
