Levenhuk Strike 90 PLUS - Инструкция по эксплуатации - Страница 12

Introduction

Strike 90 PLUS telescope is manufactured to the highest standard and deliver images without any chromatic aberrations.

Before using your new telescope, please read this manual carefully, as it is very important to assemble your telescope properly 
for it to function at its best.

Consider using the telescope for terrestrial observations before attempting any astronomical observations. This will allow you to 
familiarize yourself with the optics and the main features of the telescope and its accessories.

Thanks to the diagonal prism in the telescope, it will always provide upright and correctly left-to-right oriented images.

It is recommended to begin observations with the low power KF20 mm eyepiece. Changing to a PF6 mm eyepiece will increase 
the power of the telescope, but the image will appear dark and blurred. This is due to the basic physical properties of the 
optics: the higher the power of the eyepiece, the less sharp the resulting image, and the narrower the field of view.

When using your telescope, be very careful and patient. At the highest power even the slightest movement of the telescope may 
destabilize the image and move the observed object out of view.

With practice you will learn how much magnification an eyepiece provides, and how much movement to expect with each 
eyepiece.

Accessories

Assembly Instructions

Red dot finder: 

Used to locate objects before using the telescope tube.
Please note that the red dot finder has to be aligned to the telescope tube prior to any observations.

Diagonal prism

Allows for optically correct upright views through your telescope

3х flip Barlow lens:

Used to triple the power of any given eyepiece, e.g. a 20 mm eyepiece yields 30x power, but if used with the 3x Barlow lens, it 
yields 90x power.

Eyepieces:

6 mm eyepiece, 100x (300x with 3x Barlow lens) 
Yields the highest power, but the resulting images are the least sharp
20 mm eyepiece, 30x (90x with 3x Barlow lens)
Yields the lowest power, but the resulting images are the brightest
Zoom eyepiece F6.8-F16 mm yields 88x-37.5x (264x-112.5x with 3x Barlow lens)

permanent eye damage or even blindness.
