Photron Ritchey-Chrétien Optical Tube Assembly
INSTRUCTION MANUAL
WARNING!
NEVER USE A TELESCOPE TO LOOK AT THE SUN! Looking at or near the Sun will
cause instant and irreversible damage to your eye. Children should always have
adult supervision while observing

Welcome to a new world of adventure! The
iOptronŸ Photron Ritchey-Chrétien design telescopes
feature low thermal expansion quartz primary and
secondary mirrors with ninety-nine percent reflective
dietetic coatings. The RC optical design delivers
coma, spherical and chromatic aberration free results,
perfect for color or monochrome imaging. A fixed
position primary mirror eliminates image shift that
occurs from focusing with other telescope designs.
The telescope comes with a dual-speed
linear-bearing Crayford focuser. Three focuser
extension rings are provided for a “flex-free” solid
extension as a means to take up any unneeded back
focus. Its steel tube is equipped with 10 knife edge
baffles to diminish contrast reducing stray light,
improving the instrument in both visual and imaging
uses.
These instructions will help you set up and properly
use and care for your telescope. Please read them
over thoroughly before getting started.
Parts List
1 Optical tube assembly with dual-speed focuser
1 2” to 1.25” Compression ring adapter (installed)
1 2” extension ring
2 1” extension rings
1 Battery holder (RC10 only)
Getting Started
Your telescope comes fully assembled from the
factory. The optics have been installed and
collimated, so you should not have to make any
adjustments to them. Keep the dust covers on the
telescope when it is not in use.
Mounting the Telescope
The iOptron RC has a preinstalled dovetail rail for
mounting the scope quickly and directly onto an
altazimuth or equatorial mount. The RC6 has a
Vixen-style dovetail bar, while RC8 or RC10 has a
Losmandy-style one.
Selecting an Eyepiece
All RC scopes can accept 2” or 1.25” eyepieces, via a
2” to 1.25” adapter.
Always begin viewing with the lowest power eyepiece.
(Note: a 20 mm focal length eyepiece is lower power
than a 10 mm one.) A formula can be used to
determine the power of each eyepiece: Telescope
focal length divided by eyepiece focal length equals
magnification. For example, a RC8 has 1600mm in
focal length, the magnification with a 20mm lens is:
1600mm Ă· 20mm = 80X
Focusing Telescope
All iOptron RC telescopes come with a dual-speed
Crayford focuser. Each focuser is also equipped with
both a tension adjustment knob for the drawtube and
a drawtube locking knob. We recommend keeping
the tension adjustment knob fairly tight at all times as
this will minimize drawtube flexure and slippage.
The 6" RC features a 2" Crayford focuser equipped
with a removable 1.25" adapter. The tension
adjustment knob and the drawtube locking knob are
on the underside of the focuser,

The 8" RC has a 2" linear-bearing Crayford focuser,
which has a stabilizing track on the underside of the
drawtube that provides extra rigidity for carrying
heavy payloads. The tension adjustment knob is on
the underside of the focuser while the larger locking
knob is on top.
The 10" RC also boasts a linear bearing focuser, but
with an oversized housing and a larger 3.3" drawtube
that terminates in a 2" accessory collar. It has a
stabilizing track, too. The tension adjustment knob is
on the underside of the focuser while the larger
locking knob is on top.
Point the telescope so the front end is aimed in the
general direction of an object you wish to view.
Release drawtube lock knob so the drawtube can
be moved while turning the focus knobs. Select a
proper diagonal and eyepiece if you are doing visual
observation. Adjust the drawtube tension
adjustment knob for a proper tension during adjust
the focus knob. Look through the eyepiece while turn
the coarse focus knob to move the drawtube outward
until you see the image. Turn the fine focus knob until
the image becomes sharp. Go a little bit beyond
sharp focus until the image just starts to blur again.
Then reverse the rotation of the knob just to make
sure you’ve hit the exact focus point. You will have to
readjust the focus when aiming at subjects of varying
distances, or after changing eyepieces.
If the focuser drawtube is fully extended and you are
still unable to achieve focus, you will need to install
one or more extension rings (see next section).
Practice this during daytime by aiming the main
telescope tube at a land-based target at least œ miles
away.
The focuser can be rotated to a desired angle prior to
