A simple optional accessory is required to mount a parallel telescope.
In order to install this accessory it
is necessary to remove the plastic
plug that has the Avalon logo
(fig. a). This removal enables the
mounting flange (fig. b) to be
inserted.
This flange holds the Dual-DEC
accessory for mounting the
Secondary Vixen dovetail saddle
(fig. c) or the X-Guider (fig. d).
The X-Guider is moveable in two directions, which allows perfect alignment of two telescopes.
When used with a second telescope for auto-guiding, it also allows the slight misalignment
required to search for a suitable guide star.
The figures below show the optional kit components described above.
