in the mounting saddle with no wobbling.

Choosing the Telescope
The M-zero obs is an extremely versatile mount and can carry several varieties of telescopes, it
can be set for continuous operation without the need to perform the “meridian flip”. This can be
facilitated by the appropriate choice of a telescope.
Another benefit of the M-zero is its ability to mount two parallel telescopes. This feature offers
a wide range of advantages, such as simultaneous observation with different filters or auto-
guiding.
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.
