ORION TELESCOPES & BINOCULARS 5525 Manual

Orion 2" Multiple Filter Wheel
#5525
Congratulations on your purchase of a quality Orion acces-
sory. The Orion Multiple Filter Wheel allows use of up to
four 2" filters without the time-consuming and sometimes
frustrating process of removing an eyepiece or imaging
system every time a different filter is needed. With its inno-
vative design and compatibility with all 2" Orion filters, the
Orion Multiple Filter Wheel lets you dial in the details of
virtually any celestial object with a simple turn of the wheel.
It's so easy!

Parts List

1 Filter Wheel Assembly
1 2" nosepiece
1 Camera adapter
1 Lock ring
1 Hex key

Filter Installation

To install your 2" filters into the Multiple Filter Wheel you
will need to partially disassemble the filter wheel. Use the
supplied hex key to unthread the four socket-head screws
of the front (non-labeled) panel of the filter wheel assembly
(Figure 2). Be sure to place the screws in a safe place so
they do not become lost or damaged. Once all four screws
have been removed, gently separate the front plate from
the filter wheel, but be careful so the internal filter tray does
not fall out of the assembly. Carefully remove the tray by
grasping the central plastic hub and pulling gently. Now you
can install the 2" filters of your choice into the hub simply
by threading them into the rear (unlabeled) side of the filter
tray (Figure 3). You may wish to note the number designa-
tion of each installed filter for convenient reference during
use (Figure 4). You may find it useful to leave one of the
four threaded filter locations empty, providing an unfiltered
option for viewing or imaging. Once you have installed all
the filters you wish to use, carefully place the filter tray back
into the wheel assembly. Be sure the small plastic tab fully
registers with the central hole of the wheel assembly so that
it "clicks" into place. Position the rear plate so that the open-
ing is aligned with the opening of the front plate. Complete
the installation by reattaching the rear plate of the filter
wheel assembly with the socket-head screws.

Attaching a Camera to the Filter Wheel

The Multiple Filter Wheel is intended for astro-imaging
with a camera body, be it a SLR camera, CCD, or CMOS
device. To attach a SLR camera to the filter wheel, use the
included T-thread ring and a T-ring built for your SLR model.
Attach the side of the T-thread ring with fewer threads to
the rear (labeled) plate of the wheel assembly by rotating
it clockwise until tight. Now thread your SLR camera T-ring
onto the exposed T-threads (Figure 5).
If you are using a digital imager that features T-threads,
you can attach it directly to the Multiple Filter Wheel. If your
digital imager has a 2" nosepiece, remove it to expose the
