StarBlast parts:
17mm Explorer II eyepiece
The eyepiece is the part of the telescope that you actu-
ally look through to see things. The focal length of the
eyepiece and the telescope determines the magnifying
power. Magnification is discussed in more detail in the
Using Your Telescope section.
EZ Finder II reflex sight
This is a special “finder” that helps you aim the tele-
scope and locate objects in the sky for viewing. The EZ
Finder II generates a red LED “dot” that shows where
your telescope is aimed. The use of the EZ Finder II is
discussed in the Getting Started section.
Optical tube
This is the main component of the telescope.
Focuser
This is where the eyepiece is placed, and it is where
you focus. Details of the focuser are shown in Figure 2.
Tube clamp
This clamp connects the optical tube to the wood base.
Altitude tension adjustment knob
By tightening or loosening this knob, you can change
the amount tension in the altitude (up/down) motion of
the telescope.
Mirror cell
This contains the primary mirror as well as the colli-
mation thumbscrews that are used to optically align the
primary mirror. This is explained in Appendix A:
Aligning the Mirrors.
Altazimuth base
This wooden base provides a stable mount for the tele-
scope. It allows you to move the telescope in altitude
(up/down) and azimuth (left/right).
Carrying handle
This convenient handle built into the base allows you to
easily carry the StarBlast to your viewing location. The
carrying handle is also a handy place to put your other
hand when aiming the telescope. See Using Your
Telescope for more details.
Eyepiece rack
A handy metal rack in which to store your extra eyepieces.
6mm Explorer II eyepiece
The higher-power eyepiece that comes with the StarBlast
Eyepieces are discussed in the Magnification section.
Rubber feet
Three feet provide support for the StarBlast and are
skid free. This allows you to place the StarBlast on
smooth surfaces.
Figure 2 shows detail of the focuser
Focus Wheels
The focus wheels are used to bring objects into focus.
By turning them, you move the rack-and-pinion
focuser (4) in and out.
Eyepiece securing thumbscrews
These thumbscrews are used to keep the eyepiece (1)
secure in the focuser (4).
Items not shown
Primary Mirror
The parabolic mirror at the rear of the optical tube (3)
gathers incoming light and focuses it with its parabolic
shape. The primary mirror has a small center-mark that
is explained in Appendix A. This center-mark should
not be removed.
Secondary Mirror
The secondary mirror is located near the opening of the
optical tube (3) and reflects the focused light from the
primary mirror into the eyepiece (1).
Collimation cap
This small cap fits in the focuser and is used to aid in
aligning of the optics. This process is explained in
Appendix A.
