Astro-Physics Command Center (APCC) Software

Skip to the order and download information if you already know about the program.

The Astro-Physics Command Center (APCC) provides advanced mount control features useful for local or remote operation of your Astro-Physics GTO mount. It was developed by Ray Gralak, the author of PulseGuide and PEMPro in collaboration with Astro-Physics.

Whether you are controlling your mount while seated at your computer six feet or half a world away, there are functions to provide you with a more productive and pleasurable experience. Comet or satellite trackers will love the custom rates and 3600GTO owners with limit switches and/or precision encoder will appreciate the user interface. Through the application of virtual serial ports, APCC will act as a hub for a number of other applications that can all communicate with the mount through a single COM port. APCC provides useful safeguards even if you are operating your scope in your backyard.

APCC is offered in two versions: APCC Standard (APCC-ST) and APCC Pro (APCC-PRO). We also offer an upgrade option from Standard to Pro Version (APCC-UP) whenever you wish to use the additional features.

APCC Standard Version (APCC-ST), includes Horizons

Features of APCC Standard APCC Pro Version (APCC-PRO), includes Horizons

Features of APCC Pro

IMPORTANT: APPM requires one of the following for plate solves:

Astro-Physics Horizons - Bonus Application

Horizons allows your Astro-Physics mount to accurately follow solar system objects such as Comets, Asteroids, Planets, and even the moon and sun. It uses data that you import from the JPL Horizons Ephemerides web site to calculate the precise tracking rates needed to follow a target without any guiding. This means you can do longer unguided exposures of a comet without it blurring. Or, in the case of fast moving asteroids, you don't need to worry about keeping your scope centered because Horizons will do that for you.

APCC and Astro-Physics Horizons Demonstration

In the video below, Howard Hedlund, from the Astro-Physics Technical Support staff, demonstrates key features of APCC Pro and the Astro-Physics Horizons program at the Northeast Astronomy Forum (NEAF) in Suffern, NY in April 2013. Dennis DiCicco, Sky & Telescope editor, conducted the interview. If you wish to skip ahead and view only the APCC portion of this video, start at 13:50. However, we invite you to view the entire video for demonstrations of these exciting products: 1100GTO and 1600GTO German Equatorial mounts with discussion of the Absolute Encoder System, Right-Angle Polar Alignment Scope and the 10 x 60 Vario Finder with Quick Release Guider Bracket.


Here are a couple of screenshots to give you an idea of the interface.

This is the Main Window of the APCC Pro Version. The Setup Tab is visible and various other tabs, the 3D View or Status Window can be easily selected. The telescope position values continually update and the graphic plots the position of your telescope and indicates the pier side. Move commands are readily available as is the status bar on the lower portion of the window. Connection information is always visible. Note that you can set up a backup COM port that will be available if you experience connection problems with your primary port. The circular help buttons direct you to the specific part of the manual that discusses the function of the group box - a very handy and useful feature!.

The 3D scope view is a separate window that can remain open alongside the main window, if you wish. It provides a visual representation of the movement of your mount and telescope relative to the pier. The dimensions of the telescope, dewcap, focuser, camera and pier can all be edited (and saved for future use) to provide a fairly accurate graphic of your instrument. However, we do not recommend that you rely solely on this graphic as you move into tight positions near the pier. Nevertheless, this is a very useful (and fun) tool.

Hardware and Software Requirements

Mount Hardware Requirements

Minimum Recommended Computer Hardware Requirements
The whole idea of "minimum computer requirements" for a single application is really no longer valid in today's computer world. Any computer that can run any of the modern software packages that you will be using with APCC will be adequate to run APCC. The issue in today's environment is whether your computer can run ALL of the required software SIMULTANEOUSLY to achieve your desired goals. APCC is unlikely to ever be run as a stand-alone piece of software. When you consider your computer hardware, aim for a system that can handle all of the observing and imaging software that you plan to use, and that can handle all of it running together. That being said, here are some general tips and recommendations and a few specific requirements:
