4.1. Getting Familiar with Telescope

It is strongly suggested to practice how to use the telescope and mount during the daytime to get familiar with all the functionalities. Since the attached glass solar filter will block more than 99.99% of the light, you will not see anything other than the sun if the filter is not removed.

Warning: once the solar filter is removed from the telescope, it will no longer be a Solar Scope. Never aim the telescope at the sun if the solar filter is removed or damaged.

4.1.1. Using the telescope

Imaging Orientation:

The image orientation changes depending on how the eyepiece is inserted into the telescope. When using the star diagonal (the included 90º mirror diagonal), the image is right-side-up, but reversed from left-to-right (i.e., mirror image). If inserting the eyepiece directly into the visual back (i.e., without the star diagonal), the image is upside-down and reversed from left-to-right (i.e., inverted). This is normal for the refractor design.

For terrestrial observation, such as land mark or bird viewing, you can buy an optional 45º Erect Diagonal to have a correct image from your eyepiece.

Selecting an Eyepiece:

The magnification of a telescope is defined by the focal lengths of the telescope and the eyepiece. A formula can be used to determine the power of each eyepiece: Telescope focal length divided by eyepiece focal length equals magnification.

For example, a Solar 60 telescope has a focal length of 360mm. It comes with a 25mm eyepiece. Therefore the magnification will be

360mm ÷ 25mm = 14.4X (magnification)
