Cooling the telescope:
Telescopes require time to cool down to outside air temperature. This may take longer if there is a big difference between the temperature of
the telescope and the outside air. This minimizes heat wave distortion inside telescope tube (tube currents). Your telescope would require at
least 15 minutes cooling off to outside conditions. Tip: use this time for planning your session and mount accessories.
Using the telescope for visual observation
● NEVER USE YOUR TELESCOPE TO LOOK DIRECTLY AT THE SUN.PERMANENT
EYE DAMAGE WILL RESULT.
● NEVER USE AN EYEPIECE-TYPE SOLAR FILTER.
● NEVER USE YOUR TELESCOPE TO PROJECT SUNLIGHT ONTO ANOTHER
SURFACE; THE INTERNAL HEAT BUILD UP WILL DAMAGE THE TELESCOPE
OPTICAL ELEMENTS.
● USE A PROPER SOLAR FILTER FIRMLY MOUNTED ON 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 LET A TELESCOPE POINTING THE SUN UNATTENDED.
