WARNING!
NEVER USE A TELESCOPE TO LOOK AT THE SUN WITHOUT A SOLAR FILTER!
Looking at or near the Sun will cause instant and irreversible damage to your eye.
Children should always have adult supervision while observing.

1. Description
iOptron® Solar 60TM refractor telescope (Solar60) combines iOptron’s 60mm f/6 achromatic
refracting telescope and a durable SolarLite solar filter from Thousand Oaks. With the thread-on
solar filter design, the S60 provides a safer view of the solar photosphere. Watching sunspots
change and travels across the disk of sun day by day.
With fully multi-coated air-spaced doublet optics, the S60 reveals brighter and sharper
images. Explore and view the details of the Moon phases by removing the Solar Filter. The 60mm
objective lens and short 360mm (f/6.0) focal length are perfect for taking in wide swaths of the
night sky.

2. Telescope Setup
The Solar60 telescope comes with a Vixen-type dovetail. It can be mounted onto any
telescope mount that accepts a Vixen-type dovetail. Just simply release the dovetail locking knob
on the dovetail saddle. Slide the telescope dovetail bar in and lock the dovetail locking knob.
Figure 2. Install the Solar60 telescope onto a telescope mount
If you only have a camera tripod, you can mount the telescope onto it via a ball head, which
will provide needed telescope movement. There is a ¼” threaded hole on Solar60 dovetail bar.
Install the quick release plate of the ball head onto the dovetail bar and insert the quick release
plate to the ball head and secure it.

Insert the diagonal into the eyepiece side of the telescope. Tighten the thumbscrews to a
firm feel only. Slide the eyepiece into the open end of the diagonal. Tighten the thumbscrew.
Remove the dust cover from the other end of telescope before observation.

3. Telescope Operation
3.1. 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.
3.2. 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 Solar60 telescope has a focal length of 360mm. With a 25mm eyepiece, the
magnification will be
360mm ÷ 25mm = 14.4X (magnification)
If you want more magnification, you may order higher power eyepieces. Note: a 25 mm
focal length eyepiece has a lower power than a 10 mm one. Always start with the lowest power
eyepiece for easy locating the objects.
3.3. Focusing Telescope
Practice telescope focusing during the daytime to get familiar with the scope.
(1) Remove dust cap and unscrew the glass solar filter from the telescope.
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.
(2) After selecting the desired eyepiece aim the telescope tube at a land-based target at
least 200 yards away (e.g. A telephone pole or building). Fully retract focusing tube by turning the
focus knob.
(3) While looking through selected eyepiece, slowly extend focusing tube by turning
focusing knob until object comes into focus.
