In order to be very sure and protect your vision, for viewing the moon and sun, use a projection
screen. You can obtain these as accessories. For initial tests, it is certainly sufficient to build a
projection screen, as per the following example:
Take a box and cut out a 10 x 10 cm piece. Cut a circular hold in the size of the eyepiece bracket
in the middle, and poke through two additional smaller holes ( 1 top right, 1 bottom left) approx.
2 cm from the edge (see Fig. Part B). Then, take 2 thick straws and affix them over the holes. Cut
another piece (approx. 10 x 10 cm) out of the box, and paste white paper on one side.
Poke 2 holes in the same positions as for the first part.
Now place the 2nd part (A) onto the straws, with the white side facing toward the opening of B.
Finally, place the self-built projection screen on the eyepiece bracket. By moving back and forth,
you can focus the white projection screen, until you seen an image. You will have good and safe
eye protection.
Remember: Never look directly at the sun. Like a laser breaking through an armoured door, you
can lose your sight.
Caution:
Sun observations always only without an eyepiece, as this can be damaged from intense heat
development.
