when you are finished. By using the markings on the knobs, you can easily undo any errors or estimate the magnitude of
your next adjustment.

Tweaking Your Alignment

As a final thought on altitude and azimuth adjustments, some people love to tweak their alignment. Tweaking the azimuth
should no longer pose any issues since the Precision Adjust Rotating Base and Hi-Res Azimuth Adjuster do NOT introduce
any shifting into the process. If you do make a final altitude tweak, however, DO NOT loosen or further tighten the altitude
locking knobs lever. Resist the temptation and leave the altitude locking knobs alone!

Mach2GTO Daytime Polar Alignment Method

1. Roughly aim the mount using a compass (or phone app)
toward the pole in azimuth.
2. Approximately level the mount with the bubble level (or
phone app).
3. Set up your scope and equipment on the mount, balance,
and tighten clutches.
4. Power up the mount and unpark. This will initialize the
Mach2GTO.
5. Command the mount to go to Park 5 (see Park position in
"Appendix A").
6. Use a carpenter's level and turn the altitude knob until the
scope is level.
7. Tell the mount to GoTo a visible object: the sun (with solar
filter protection), the moon, bright planets or stars.
8. Use the azimuth adjuster until the object is centered in the
field.
9. You are polar aligned and ready to start observing!
You can repeat this process (#5 to #8) to gain accuracy. This
will provide accuracy for visual observing.

Using Software to Improve Pointing Accuracy

Software solutions are available today that will help to compensate for orthogonal problems as well as other idiosyncrasies
of your telescope, mount and optics. These programs analyze and compensate for these problems, resulting in improved
telescope pointing performance. Note: Only APCC Pro will also provide high-precision, dual-axis tracking compensation.
● Astro-Physics Command Center (APCC PRO), Pro version with pointing and dual-axis tracking model. This software
was provided with your Mach2GTO,
● Astro-Physics Keypad, version 5.xx firmware allows the creation of an orthogonality routine as well as pointing model
and tracking models.
● MaxPoint™ Modeling Software from Diffraction Limited,
● TPoint™ Modeling Software from Software Bisque,

Both Hemispheres:
North: Dec = (90-Latitude) South: Dec = (-90-Latitude)
The southern hemisphere is mirror reversed. The
scope is still level on the east side of the mount, but
is facing the southern horizon.
The counterweight
