AutoStar #497 HANDBOX

so that center tick mark on fork arm base 

(

Fig. 24, A

) aligns with the tick mark on the 

base (

Fig. 24, B

). Lock the RA.

 

e.

 Press ENTER. The telescope slews to Polaris.

 

f. 

Use the azimuth and latitude controls on the 

X-Wedge to center Polaris in the fi eld of view. 

Do not use the AutoStar II handbox during this 

process. When Polaris is centered, press ENTER. 

Lock the locking screws on the X-Wedge. The 

telescope will then slew to an alignment star 

and ask you to center it. Once you have done 

tis press ENTER. The telescope is now polar 

aligned. 

See AUTOSTAR II POLAR ALIGNMENT, 

on this page, for more information.

At  this  point,  your  polar  alignment  is  good  enough  for 

casual observations. There are times, however, when you will 

need to have precise polar alignment, such as when making 

fi ne astrophotographs.

Once the latitude angle of the wedge has been fi xed and locked-

in according to the above procedure, it is not necessary to 

repeat this operation each time the telescope is used, unless you 

move a considerable distance North or South from your original 

observing position. (Approximately 70 miles movement in North-

South observing position is equivalent to 1° in latitude change.) 

The wedge may be detached from the fi eld tripod and, as long 

as the latitude angle setting is not altered and the fi eld tripod is 

leveled, it will retain the correct latitude setting when replaced 

on the tripod.

The fi rst time you polar align the telescope, check the calibration 

of the Declination setting circle. After performing the polar 

alignment procedure, center the star Polaris in the telescope 

fi eld. On the left fork arm, loosen the large smooth knob centered 

in the setting circle. With the knob loose rotate the setting circle 

until it aligns with 89.2 degrees with the pointer. While holding it 

in place, tighten the large smooth knob.

Should you wish to use the manual setting circles, the RA 

setting circle (

Pg. 58, Fig. 20

) must be calibrated manually on 

the Right Ascension of a star every time the telescope is set up.  

(The RA setting circle has two sets of numbers, the inner set 

is for Southern hemisphere use, while the other is for Northern 

hemisphere use.) Locate a star with which you’re familiar. Look 

up the RA for the star in a star chart or other aid. With the star 

centered in the telescope’s eyepiece, move the RA setting circle, 

using one of knobs (

Fig. 24, C

), so that the RA of the star lines 

up with the tick mark on the base of the telescope (

Fig. 24, B

).

Precise Polar Alignment

It should be emphasized that while doing casual observing, 

precise alignment of the telescope’s polar axis to the celestial 

pole is not necessary. Don’t allow a time-consuming effort at 

lining up with the pole to interfere with your basic enjoyment 

of the telescope. For long-exposure photography, however, the 

ground rules are quite different, and precise polar alignment is 

not only advisable, but almost essential.

Even though the LX600 ACF telescopes offers a very precise 

and sophisticated drive system, the fewer tracking corrections 

required during the course of a long-exposure photograph, 

the better. In particular, the number of Declination corrections 

required is a direct function of the precision of polar alignment.

Achieving precise polar alignment can be done with Starlocks 

assistance or manually using a crosshair eyepiece. See Polar Drift 

Alignment on page 43 for more information on using Starlock to 

obtain a precise polar alignment. If you wish to manually obtain a 

precise polar alignment, the Meade Astrometric Reticle Eyepiece 

(

see OPTIONAL ACCESSORIES, page 44

) is well-suited in this 

application,  but  it  is  also  preferable  to  increase  the  effective 

magnifi cation through the use of a 2X or 3X Barlow lens as well. 

Follow the procedure on 

page  68,  Appendix  G:  Manual  Drift 

Alignment

  to obtain a precise polar alignment without Starlocks 

assistance. When performing this procedure, turn off the Starlock 

in the Utilities menu.

Achieving precise polar alignment can be done with Starlocks 

assistance or manually using a crosshair eyepiece.

AutoStar II Polar Alignment

AutoStar II provides three different (manual) methods for polar 

alignment: Easy, One-Star and Two-Star. 

One-Star Polar Alignment (Default)

Setup the telescope facing true north with the tripod level. Use 

Fig. 24. 

Align tick marks to set the fork arms to 00 H.A. position.
