ABOUT THIS MANUAL
This version of the 1100GTO, 1100GTO-AE and 1100GTO-AEL Manual was prepared for the production run of mounts that
began shipping in November of 2018. There are a few feature differences between the encoder and non-encoder versions
of the mounts that warrant special attention and connection procedures. Whereas some division of context is provided
within this manual, these differences will primarily be addressed in the separate AP AE Utility CD that is provided with the
1100GTO-AE and 1100GTO-AEL mounts.
You should also note that this manual is actually one component of a three document system. If you choose to purchase
the optional Keypad, then you’ll receive its manual. The Keypad Manual applies to all mounts, detailing the keypad’s many
features and extensively explains its operation. The third manual is the GTO Servo Motor Drive System. Like the Keypad
Manual, the GTO Manual is universal to all mounts that use the Astro-Physics GTO Servo Motor Drive System with the
GTOCP4 Servo Control Box. This 1100GTO, 1100GTO-AE and 1100GTO-AEL manual, on the other hand, will cover the
1100GTO’s mechanical features and physical operations.
As always, we highly recommend the Technical Support Section of our Web site for the latest information and for future
updated versions of this manual.
A final note and an apology to our friends in the southern hemisphere. Many of the instructions in this manual are written
entirely from the point of view of those of us in the northern hemisphere. Since descriptive terms like left and right are
meaningless without a defined point of reference, we tend to use east and west to avoid ambiguity. The east and west
sides of a German equatorial mount are, of course, reversed in the southern hemisphere. At one point, our thought was to
always use phrases like the following: “... on the east side (west side in the southern hemisphere) ...” This quickly became
cumbersome and made the text more difficult to read. For simplicity, we decided to leave many of the explanations in their
northern hemisphere framework. To our southern hemisphere friends:
We appreciate you no less and apologize for this
unintended slight.
We know, however, that you are all smart enough to make the necessary translation to “down under”
appropriate instructions. Thank you for your understanding.
Note: Some photos may differ slightly from the current mounts that are shipping.
