Orion 9814 instruction manual StarBlast parts

Congratulations on your purchase of an Orion StarBlast telescope. Your new StarBlast is easy to use and requires very little assembly. The StarBlast will give you breathtaking views of the Moon, planets, and even deep sky objects like the Orion Nebula. These instructions will help you set up and use your StarBlast telescope, please read them thoroughly.

StarBlast parts:

1	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.
2	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.
3	Optical tube
	This is the main component of the telescope.
	Focuser

116mm Explorer II eyepiece

The higher-power eyepiece that comes with the StarBlast Eyepieces are discussed in the Magnification section.

12Rubber feet

Three feet provide support for the StarBlast and are skid free. This allows you to place the StarBlast on smooth surfaces.

13Focus 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.

14Eyepiece securing thumbscrews

These thumbscrews are used to keep the eyepiece (1) secure in the focuser (4).

	you focus. Details of the focuser are shown in Figure 2.
5	Tube clamp
	This clamp connects the optical tube to the wood base.
6	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.
7	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.
8	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).
9	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.

Items not shown

15Primary 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.

16Secondary 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).

17Collimation 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.
