About this product

Model:  vixen_ap-sm_mount
Part Number:  79973

The new AP mount is effectively a replacement for the venerable GP2 - a lightweight, portable EQ mount that can be upgraded with motors and manual or GOTO controller. Where it differs from the GP2 is in its modular design.

This is the SM motorised model which features a motorised R.A axis and Star Book One controller. The manual DEC axis can be motorised using the upgrade motor module available separately.

As shown in the diagram below, it can be broken down into various parts. This allows the mount to be used in a variety of different ways.
