Hyperion
12.5” f/8 Astrograph
Operating Instructions
Thank you for purchasing a Hyperion telescope. You now own the most state-of-the-art
astrograph available. In addition to providing a large aberration-free flat field, the
Hyperion comes standard with a wealth of features.
This instruction manual will describe in detail the proper use of the Hyperion and its
many features. Please note the Warnings given in the ne t section in order to avoid
damaging your Hyperion.

Things Not to Touch
There are two adjustments made when the telescope is assembled and tested that should
not be adjusted by the user. First is the secondary mirror spacing. This is adjusted by a
nut located under the cover plate on the spider hub.
Don’t go there
Second is the corrector lens tip/tilt adjustment. This is located about halfway down the
outside of the primary baffle tube.
Don’t go there
Caution
Colli ation Bolts
The primary mirror assembly (including the mirror cell, mirror, baffle tube, and corrector
lenses) is held in place by the primary mirror collimation screws on the telescope back
plate. Do not loosen these screws too much or the whole assembly will fall off (this is a
bad thing), or more likely one screw will pop loose and you will have to take off the back
plate to reattach it. When collimating the telescope, make only small adjustments as the
telescope was collimated before shipping and should require only a little tweaking.
Same goes for the secondary assembly. It is held in place by its collimation screws.
Again, don’t loosen these too much or the assembly can become detached (another bad
thing). Make only small adjustments to the collimation screws. More details are in the
section on collimation.
Focuser and Instru ent Rotator
The focuser and instrument rotator are designed to be moved electronically with their
motors. Do not attempt to move these units by hand. If for some reason is it necessary to
move the focuser drawtube manually, you may remove the motor and turn the focus knob
by hand. Note that there is a tension knob on the bottom of the focuser. When the
focuser motor is attached and in use, the tension knob should be loose.
The instrument rotator should never be moved by hand. Manual rotation of the focuser
can be achieved by loosening the lock collar on the Feathertouch focuser. Note that the
inde ing of the rotator is independent of the position of the focuser, so adjusting the
focuser’s rotation from its initial position is not necessary.
Telescope Overview
Back Plate Features
Located on the Hyperion’s back plate are the primary mirror collimation screws,
Telescope Control Panel, instrument rotator, focuser, and cooling fans.
There are si collimation screws—three adjustment and three lock screws. Recall that
the large screws are the only thing holding the primary mirror assembly. Use caution
when adjusting these screws. The screws are described in more detail in the section on
collimation.
The Telescope Control Panel is the brains of the operation. This panel features an LCD
display and controls the instrument rotator, main Hyperion focuser, an optional
piggyback instrument focuser, cooling fans, and dew heaters. These features can also be
controlled remotely from a computer using the Telescope Control Software. More details
are in the section on the Telescope Control Panel and Telescope Control Software.
The high-precision instrument rotator allows accurate positioning of the camera for
framing a target or finding a guidestar. It can be controlled through either the Telescope
Control Panel or the Telescope Control Software.
Dual cooling fans move filtered air around the primary mirror and through the optical
tube to accelerate thermal stabilization of the optics. This reduces the effect of tube
currents which can degrade seeing conditions.
The Hyperion uses a 3.5” Feathertouch Focuser for precise focusing. The focuser is
automated using Starizona’s MicroTouch autofocuser. The Feathertouch has 4.5”
(115mm) of focus travel and tick marks on the side of the focuser drawtube indicate the
current travel of the focuser in mm. The Hyperion has 7.33” (186mm) of backfocus from
the racked-in focuser drawtube to the focal plane. This distance does not include the
thickness of the focuser adapter, which varies by camera, but is appro imately 1”
(25mm) thick.
Other Features
The Hyperion features top and bottom Losmandy-style dovetail plates. The top dovetail
is ideal for piggybacking an optional guidescope or other wide-field instrument. The
dovetail will accept standard Losmandy accessories such as mounting rings and allows
you to balance the telescope by sliding the piggybacked instrument front to back. When
adding a second instrument, consider not only the weight of the instrument but also the
leverage due to the distance from the mount. This may make some instruments
impractical for some mounts. The distance between dovetails is 16” (406mm) and each
dovetail is 19.75” (502mm) long.
The secondary mirror is collimated with three screws attached to the triangular plate on
the spider assembly. A reminder that these three screws are the only thing holding the
secondary mirror assembly in place. Use caution when adjusting these screws. These
screws are described in more detail in the section on collimation.
The Hyperion has both primary and secondary mirror dew heaters to prevent moisture
from building up. The heaters can be controlled through either the Telescope Control
Panel or the Telescope Control Software.
Unique to the Hyperion is the ability to control all electronic features wirelessly. This is
done through the wireless control bo . The control bo plugs into your computer via a
USB cable and talks wirelessly to the Hyperion up to 300 feet away.
Colli ation
While the Hyperion was collimated and tested before being shipped, it likely will need
some slight adjustment after arrival. This section describes the full procedure for
properly collimating the Hyperion. The adjustments should be made in the order outlined
below.
Secondary Mirror Tilt
This is best evaluated using an optional laser collimator. Use the included 2” end cap for
the Feathertouch focuser to attach the laser collimator.
With the laser in place, look in the front of the scope. Look for the reflection of the
secondary mirror in the primary mirror. You should see the laser being emitted from the
bottom of the laser collimator. You should also see that the beam bounces off the
secondary and returns right on itself. If you see two red spots on the collimator, the beam
is not returning e actly onto itself and you need to adjust the secondary mirror.
This adjustment is done using the secondary collimation bolts. In order to adjust the
secondary mirror tilt, begin by loosening one of the collimation bolts (say, ¼ turn), then
tighten one or both of the other bolts. Remember that the bolts are the only thing holding
the secondary mirror assembly, so do not loosen them too much. Once the laser beam is
returning e actly on itself, the secondary mirror is appro imately collimated.
