• Skyscan Az will beep once when it has finished slewing to an object. Do not try to
adjust the telescope before you hear the beep.
Skyscan Az will only respond to the ESC key while slewing.
TWO-STAR ALIGNMENT
The two star alignment procedure is similar to the Brightest Star alignment, except
that the hand control will not prompt for you to select a directional region for a bright
star. Below describes a step-by-step procedure on how to perform the Two-Star
alignment.
1.
In the alignment screen, select 2-Star using the scroll keys. Press ENTER to con-
firm.
2.
The Skyscan Az will provide a list of stars available in your current sky for you to
choose as the first alignment str. Using the scroll keys, choose a star you are most
familiar with and press ENTER. The telescope will not automatically selw to the first
selected alignment star. Use the directional buttons to manually slew the telescope to
point to the object. Now look through the eyepiece and adjust the telescope so that
the object is centered in the field of view of the eyepiece. Press ENTER to confirm.
3.
Skyscan Az will now provide a list of objects for the second alignment star. Choose
a star using the scroll keys and press ENTER. The telescope will start slewing to-
wards the chosen object. When the slewing stops, adjust the telescope with the di-
rectional keys until the star is centered on the crosshairs in the finderscope. Repeat
the centering procedure to center the object in the field of the eyepiece and press
ENTER to confirm.
4.
If both alignment stars are properly aligned, “Alignment successful” will display on
the LCD. Otherwise the warning “Alignment failed” will show and the alignment will
have to be done again.
• Following is some pointers on how to choose appropriate alignment stars:
Select two stars that are at least 60 degrees apart. The more distance between the
two alignment stars, the better accuracy the alignment will produce. Choosing two
stars with the same altitude in elevation will also create a better result.
POINTING ACCURACY ENHANCEMENT (PAE)
Both the star alignment methods provide alignment adequate for any visual observing
purpose. For applications that require extra precision in a particular part of the sky,
theSkyscan Az provides a Pointing Accuracy Enhancement (PAE) function to further
improve the accuracy. The PAE can be performed in 85 zones to cover the whole sky.
The area(s) where the chosen alignment star(s) is located should be already mapped
