Congratulations on your purchase of a quality Orion StarBlast telescope. Your telescope is a high qual-
ity optical instrument for viewing the Moon, the Planets in our Solar System and the brighter deep sky
objects (when used away from city lights). It can also be used for viewing birds, wildlife and other earth-
bound objects you want to see more closely.
Below we offer assembly instructions for your telescope and gen-
eral operating instructions; detailed advice on how to use a tele-
scope, the use of popular accessories and how to find objects in
the sky can be found online in Orion's online Community Center:

WaRninG: DO NOT VIEW THE SUN without
a professional SOLAR FILTER. KEEP THE
TELESCOPE'S OPTICS COVERED IF THE
TELESCOPE IS LEFT OUTSIDE DURING THE DAY
– an uncovered lens may concentrate sunlight if
pointed near the sun and damage the telescope
or objects around it and cause eye damage if
someone looks through it without a solar filter.
