How to Focus
• Remove the dust caps from the eyepiece and telescope tube.
• Turn either one of the two textured wheels on the focuser. See photo on left on next page.
• Each zoom setting of the eyepiece requires a slightly different focus.
• Each person may need a different focus setting.
• If you wear glasses, first try looking into the eyepiece while wearing them. You may find that
you do not need to use them. People with severe astigmatism will generally obtain better views
while wearing glasses.
How to Zoom
The zoom eyepiece has a range of focal lengths from 8 to 24 mm. The larger the focal length,
the lower the magnification, and the wider the field of view. Low magnification shows a larger
area of sky in the eyepiece, making finding and centering an object much easier.
• Start by using the telescope’s lowest power to locate and center an object. See photo on left on
next page.
• Rotate the barrel so that the 24 mm focal length setting aligns with the white triangle.
• Twist the barrel to change magnifications.
• Refocus the eyepiece.
• As the eyepiece zooms to higher magnifications, the field of view decreases.
