M-zero LHQ Use for “Time Lapse” Photography
The Dual Dec accessory enables the M-zero to mount a small auxiliary telescope or a
photographic camera in parallel with the main telescope. This feature makes it more convenient
to use the mount for long exposure pictures with the auxiliary telescope serving as a
guidescope. This feature offers superior rigidity compared to systems where the guidescope or
camera is mounted in “piggyback” fashion over the main telescope. Alternatively, a DSLR
camera can be directly mounted in the place of the auxiliary tube. In the illustration shown
below the camera has a
lens suitable for wide field or “Time Lapse” photographs. The StarGO
control system is designed to directly control a DSLR camera, making that type of photography
much easier.
This section describes the mounting of the camera on the M-zero and its electrical connection to
the StarGo. More detailed information
on the use of a DSLR with the StarGO is provided
in the
StarGo manual.
Mechanical installation
Install the Dual Dec with the dovetail female bar (1) on
the opposite site of the main telescope.
Attach a male dovetail Vixen type bar (3) under the
DSLR (2) camera
using a standard
¼-20
photographic
tripod screw.
Insert the male dovetail bar inside the female one and
firmly tighten the Knob (4)
The electrical connection of the DSLR to the StarGO
panel is performed as follows, making certain that both
devices are switched off.
On the camera:
Lift the rubber tab (1) on the side of the DSLR
to
expose the input receptacles and insert the
cable connector (2) into the receptacle (3) for
the external command of the camera. Note
that the actual connector (2) could be different
from that shown in the figure.
The camera
should come equipped with the proper cable
and connector.
