SELECTING AN EYEPIECE
You should always start viewing with the lowest power eyepiece, which in this case is the 20 mm lens. Note: the base power of each eyepiece is determined by the focal length of the telescope objective lens. A formula can be used to determine the power of each eyepiece: telescope OBJECTIVE lens focal length divided by EYEPIECE focal length = MAGNIFICATION (e.g. Using the 20 mm lens, a sample calculation could look like this: 750 mm / 20 = 38x or 38 power. Telescope models will vary in focal length.)
Included with this telescope is a Barlow lens. Barlow lenses are used to double or triple the power of your telescope. Place your Barlow between the focusing tube and the eyepiece. Using the example above, your 3x Barlow lens would give you a total power of 114x or 114 power. (38 x 3 = 114x or 114 power). The magnification calculation would look like this: 750 mm /20mm = 38 power. 38 power x 3=114 power.
MFOCUSING TELESCOPE
1.After selecting the desired eyepiece, aim main telescope tube at a
2.Fully extend focusing tube by turning Rack and Pinion Focusing Mechanism.
3.While looking through selected eyepiece (in this case the 20 mm), slowly retract focusing tube by turning Rack and Pinion Focusing Mechanism until object comes into focus.
MALIGNING FINDERSCOPE
Look through Main Telescope Tube and establish a
Looking through Wide Field Finderscope, alternate tightening each Finderscope Adjustment Screw until crosshairs of Wide Field Finderscope are precisely centered on the same object already centered in Main Telescope Tube’s field of view.
Now, objects located first with the Wide Field Finderscope will be centered in the field of view of the main telescope.
