system objects as well as satellites and
then automatically track them.
The only issue I had with both APCC
and the ASCOM driver is that some of
the settings are duplicated in multiple
locations, and it can be confusing as to
which one takes precedent.

p Astro-Physics Command Center Pro software showing the Meridian Tracking Limits tab open
and with the 3D Scope View window also open and displaying the position of the telescope in
relation to the pier. Custom meridian limits can be set for different declinations (represented by the
hour-glass figure in the graph) to avoid accidental impacts when tracking your target.

telescope shows simulated views of the
scope and mount from various angles
to help you visualize its location, which
can be useful for remote observatories
or if you are sitting in your car on a cold
night and running your scope with a
remote desktop program.
The pro version of APCC offers the
ability to build a detailed dual-pointing
model (one for each side of the meridian) that works transparently even with
the mount in a counterweight-up position, so the model will keep working no
matter if you start before, or shoot past,
the meridian.

Andromeda, shot with a 5-inch refractor on

q Astro-Physics' optional Right-Angle Polar
Alignment Scope is a must-have accessory
for users who set up and take down their
equipment each night.

You can record the pointing and
tracking model using Astro-Physics Point
Mapper, a separate application included
with APCC. Note that a camera-control
program such as MaximDL or Sequence
Generator Pro is required, as well as
plate-solving software - all of which
are available from third-party vendors.
Included with both versions of APCC
is Horizons, a program that lets you
download ephemeris elements for solar

The 1100GTO offers superlative craftsmanship, design, and execution, but
when you buy an Astro-Physics product
you're also getting industry-leading
support. I can't help but rave about how
helpful George and Howard were at
Astro-Physics when I had a question or
problem with any of the hardware or
software. In addition to the traditional
online support forums, you can even
call and talk to them in person. In this
age of automated telephone directories,
Astro-Physics support and service are
simply remarkable.
When I used the 1100GTO mount, I
had to say that I felt, like Oscar Wilde,
"always satisﬁed with the very best."
