THE FRONT OF THE TELESCOPE FOR VIEWING
THE SUN. WHEN OBSERVING THE SUN, PLACE A DUST CAP OVER YOUR
FINDERSCOPE OR REMOVE IT TO PROTECT YOU FROM ACCIDENTAL
EXPOSURE. NEVER USE AN EYEPIECE-TYPE SOLAR FILTER AND NEVER
USE YOUR TELESCOPE TO PROJECT SUNLIGHT ONTO ANOTHER
SURFACE, THE INTERNAL HEAT BUILD-UP WILL DAMAGE THE
