To sync on a focus preset
If
you park your telescope
, AutoStar II remembers all the focus positions you
defined as presets and you will not need this menu.
If
you do not park your telescope
, you will need to select just one of the presets and
refocus your telescope using the Sync On menu. Then AutoStar II will then reset all
the other presets back to the focus preset positions you previously defined.

key and scroll until “Focuser Preset: Sync On Preset” displays and press ENTER
to select this menu.

most likely preset you will choose will be one that accounts for your own
eyesight).

Observing by Moving the Telescope Manually
If you wish to observe a distant land object, such as a mountain top or a bird, you can
observe by merely pointing the telescope and looking through the eyepiece.
1.
Loosen the telescope’s R.A. lock (
13, Fig. 1a
) and Dec. lock (
17, Fig. 1a
).
2.
Move your telescope to observe distant street signs, mountains, trees, and other
structures. Use your viewfinder to help site-in on an object.
3.
Center the object in the viewfinder’s crosshairs and then in the telescope eye
piece. When the object is centered in your eyepiece, remember to re-tighten the
R.A. and Dec. locks.
4.
To move telescope in the R.A. and Dec. axes again, remember to loosen the R.A.
lock and tighten the Dec. lock. Then rotate the manual slow motion control knobs
(
10, Fig. 1a)
and (
16, Fig. 1a)
.

Once you get a feel for how your telescope moves and focuses, try to view some-
Note:
Viewing conditions vary wide-
ly from night-to-night and site-
to-site. Turbulence in the air,
even on an apparently clear
night, can distort images.
Low-power eyepieces, such
as the UltraWide 24mm sup-
plied with your telescope, are
better suited to resolving
images in poor viewing condi-
tions.
