Introduction
Congratulations on your purchase of the Orion StarBlast tele-
scope! Take time to read through this manual before embark-
ing on your journey through the heavens.
Please read the separate AutoTracker Mount Manual (IN 489)
for all information relating to the mount and its accessories.
Your StarBlast telescope is designed to give you years of fun
and exciting astronomical observations. However, there are
a few things to consider before using your telescope that will
ensure your safety and protect your equipment.

The Eyepieces
The eyepiece, or ocular, is the optical element that magnifies
the image focused by the telescope. The eyepiece fits direct-
ly into the focuser. The 1.25" designation refers to the barrel
diameter of the eyepieces.
To install one of the included eyepieces:
1. Loosen the two thumbscrews on the eyepiece adapter
at the end of the focuser drawtube and remove the
protective dust cap.
2. Slide the barrel of the eyepiece into the focuser.
3. Tighten the thumbscrews to hold the eyepiece in place.
To remove the eyepiece, loosen the thumbscrews on the eye-
piece adapter and slide the eyepiece out.
Eyepieces are commonly referred to by their focal length and
barrel diameter. The focal length of each eyepiece is typically
printed on the eyepiece body. For example this telescope ships
with two 1.25" diameter eyepieces; a 25mm and a 10mm. The
longer the focal length (i.e., the larger the number), the lower
the eyepiece power or magnification; and the shorter the focal
length (i.e., the smaller the number), the higher the magnifi-
cation. Generally, you will use low-to-moderate power when
viewing. For more information on how to determine power, see
the section “Calculating Magnification.
Focusing
Using the lower power eyepiece (25mm) inserted and secured
with the thumbscrews, aim the optical tube so the front end is
pointing in the general direction of an object at least 1/4-mile
away. With your fingers, slowly rotate one of the focus wheels
until the object comes into sharp focus. A good method to
ensure you’ve hit the exact focus point is go a little bit beyond

sharp focus until the image starts to blur again, then reverse
the rotation of the knob and stop when sharp focus has been
achieved again.
Installing the EZ Finder II
Slide the base of the EZ Finder II bracket into the dovetail
holder that is pre-installed on the optical tube. The EZ Finder
II should be oriented so that the sight tube is facing the front
of the telescope ( ). Tighten the thumbscrew on the Figure 2
dovetail holder to secure the EZ Finder II in place.
The EZ Finder II works by projecting a tiny red dot (it is not
a laser beam) onto a lens mounted in the front of the unit
(Figure 3). When you look through the EZ Finder II, the red
dot will appear to float in space, helping you to pinpoint your
target object. The red dot is produced by a light-emitting diode
(LED) near the rear of the sight. A 3-volt lithium battery pro-
vides the power for the diode.
NOTE: If it is present, remove the thin plastic battery shield
tab (not shown) from the battery compartment prior to use
and discard it.
Turn the power knob ( ) clockwise until you hear the Figure 4
“click” indicating that power has been turned on. Look through
the back of the reflex sight with both eyes open to see the
red dot. Position your eye at a comfortable distance from the
back of the sight. In daylight you may need to cover the front
of the sight with your hand to be able to see the dot, which
is purposefully quite dim. The intensity of the dot is adjusted
by turning the power knob. For best results when stargazing,
use the dimmest possible setting that allows you to see the
dot without difficulty. Typically a dimmer setting is used under
dark skies and a brighter setting is needed under light-polluted
skies or in daylight.
Aligning the EZ Finder II
For the EZ Finder II to work properly, it has to be aligned with
the telescope. When the two are aligned, a celestial object that
is centered on the EZ Finder IIs red dot should also appear
in the center of the telescope’s eyepiece. Alignment of the
EZ Finder II is easiest during daylight, before observing at
night. Aim the telescope at a distant object such as a tele-
phone pole or roof chimney and center it in the telescope’s
eyepiece. The object should be at least 1/4 mile away. Now
turn on the EZ Finder II and look through it. Without moving
the main telescope, use the EZ Finder II’s azimuth (left/right)
and altitude (up/down) adjustment knobs ( ) to position Figure 4
the red dot on the object in the eyepiece. When the red dot is
centered on the distant object, check to make sure that the
object is still centered in the telescope eyepiece. If it isn’t, re-
center it and adjust the EZ Finder II’s alignment again. When
the object is centered in the eyepiece on the EZ Finders and
red dot, the EZ Finder II is properly aligned with the telescope.
Once aligned, EZ Finder II will usually hold its alignment even
after being removed and remounted. Otherwise, only minimal
realignment will be needed. At the end of your observing ses-
sion, be sure to turn off the power knob on the EZ Finder II.
Replacing the EZ Finder II Battery
Should the battery ever die, replacement 3-volt lithium batter-
ies are available from many retail outlets. Remove the old bat-
tery by inserting a small flat-head screwdriver into the slot on
the battery casing ( ) and gently prying open the case. Figure 4
Then carefully pull back on the retaining clip and remove the
old battery. Do not over bend the retaining clip. Then slide the
new battery under the battery lead with the positive (+) end
facing down and replace the battery casing.
Telescope Basics
A telescope is an instrument that collects and focuses light.
The nature of the optical design determines how the light is
focused. Some telescopes, known as refractors, use lens-
es. Other telescopes, known as reflectors, use mirrors. The
StarBlast 114mm is a reflecting telescope with a primary and
secondary mirror to gather and focus light.
Focusing
Once you have found an object in the telescope, turn the
focusing knob until the image is sharp. To achieve a truly sharp
focus, never look through glass windows or across objects that
produce heat waves, such as asphalt parking lots.
