Manual: FlipMirror II
Attaching an Imaging Camera or other Instruments
to the rear Port (Straight Light Path)
The connections on the camera side corres-
pond to those on the telescope side, but with
external threads. A camera with a large sensor
can be mounted via the T-thread or the M48
threaded ring at the rear
3
of the FlipMirror.
The mirror flips upwards; for large, rectangular
sensors, align the long side parallel to the flip-
ped up mirror, if necessary, to use the maxi-
mum aperture.
You can connect your camera using a standard
T-ring or M48 adapter. Spectrographs like the
DADOS can also be screwed directly to the
FlipMirror for the shortest possible connec-
tion. Simply remove the 2" nosepiece from
the spectrograph.
The FlipMirror is delivered with a T-2 male
thread onto which an M48 threaded ring is
screwed. Unscrew the M48 ring if necessary.
As with the telescopic connection, there
are four grub screws which can be used to
rotate or remove the connection threads. An
S52 ring dovetail is then available for further
adaptations.
Attaching an Eyepiece or a Video
Module to the upper Port
To find or center an object, you can equip the T-thread of the upper port
4
with an
eyepiece clamp of the matching height. For a very short adaptation, you can attach
the illuminated 25mm Polaris I – Measuring- and
Guiding-Eyepiece
# 2954325
with T-2-thread. The
field stop of the eyepiece (which is usually located
at the connection point from the eyepiece body to
its nosepiece) needs about the same distance to
the flip mirror as the camera sensor, so that both
are in focus at the same time. The required distance
depends on the backfocus of your camera. We
recommend the use of a focusing eyepiece holder
# 2458125
for quick and easy correction of focus
(e.g. if you wear glasses) as well as extension tubes
(fixed or variable length) from our T-2 or M48 lines.
You can use a T-2 quick changer to switch bet-
ween several combinations (e.g. various eyepieces
or cameras) without having to refocus each time.
With a Varilock on the camera side (right) and
a focusing eyepiece clamp (top), you can easily
bring both ports into focus. CCD sensors require
less back focus than DSLR cameras. To bring the
camera or eyepiece into focus at the upper port,
you may need extension sleeves.
You can also use it to easily rotate the camera into a desired position.
