PREPARING THE TELESCOPE FOR PROJECTING THE SUN ON A SCREEN (S)
CAUTION! Cover the objective lens of the finderscope so no one can look through it.
1. Insert the projection screen rod by sliding it through the opening in the finderscope bracket with
the washer end of rod toward the objective. (The washer acts as a stop. preventing the sun
screen assembly from slipping completely through the finderscope bracket.)
2. If the diagonal is in place. remove it. It will not be used for solar observation.
3. Select the lowest power eyepiece (the one with the highest numerical designation in millime-
ters) and insert it. without the diagonal. into the focus tube.
4. Select the black plate of the sun projection assembly. Slip it onto the rod. position it near the
eyepiece so that the hole is centered with the lens of the eyepiece and lock it in place. This
plate shades the white projection screen which will be put in place in a later step. The tele-
scope is now ready to observe the sun.
OBSERVING THE SUN
1. Point the telescope in the general direction of the sun without looking through it or the
finderscope. Looking at the shadow of the telescope on the ground will help in aiming 1t.
2. Hold the white plate a few inches behind the finderscope eyepiece and move the telescope
gently until you see the sun projected on the white plate. You will see a round "picture" of the
sky with the sun somewhere
in
the ··picture:· Move the telescope. using the flexible control
cables until the sun 1s centered in this proiected image of the sky.
3. Next. slip the white plate into place on the sun projection assembly rod. Position it directly in
line with the telescope's eyepiece and lock it
in
place.
4. Use the flexible control cables to make any small corrections necessary to center the sun's
image on the white screen.
5. Focus the sun·s image cin the white screen using the focus knob.
6. The proiected image will show sunspots. the ··rice-grain" structure of the solar disk, and that the
sun is brighter at the center of the disk than at the edge.
THE MOON FILTER
A moon filter has been included with your telescope for removing glare and increasing contrast
when v1ew1ng the moon. To attach it to the telescope eyepiece. screw the filter onto the threaded
end of the eyepiece.
CAUTION! The moon filter should only be used to view the moon. It is not intended for
viewing the sun. Viewing the sun through this telescope (with or without the filter), or
even with the naked eye, can cause permanent eye damage.
