Introduction
Strike 115 PLUS and Strike 135 PLUS telescopes are 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
It is recommended to begin observations with the low power 25 mm eyepiece. Changing to a 10 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
1
eyepiece.

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.
2X Barlow lens:

Used to double the power of any given eyepiece, e.g. a 25 mm eyepiece yields 36x power, but if used with the 2x Barlow lens, it
yields 72x power.

Eyepieces:
• 10 mm eyepiece, 90x (180x with 2x Barlow lens)
• Yields the highest power, but the resulting images are the least sharp
• 25 mm eyepiece, 36x (72x with 2x Barlow lens)
• Yields the lowest power, but the resulting images are the brightest
• Zoom eyepiece F7.3-F23mm yields 123x-39x (246x-78x with 2x Barlow lens)
