 Safety... 

Looking at the Sun at any time is potentially dangerous and can result in serious eye damage or blindness.

NEVER LOOK DIRECTLY AT THE SUN WITH UNPROTECTED EYES- THIS MAY CAUSE TOTAL BLINDNESS WITHIN SECONDS!

ALWAYS BE SURE TO USE PROPER OPTICAL FILTERS TO PROTECT YOUR EYES.

 NEVER LOOK DIRECTLY THROUGH A TELESCOPE TOWARDS THE SUN, EVEN WITH FILTERS (ONLY PROFESSIONALS WELL VERSED IN THESE MATTERS MAY DO SO)!

 The safest way to view the Sun is indirectly using a projection method, e.g. pinhole projection or mirror projection.

You may view the Sun directly only through a special filter made for safe solar viewing. If you are not certain the filter is approved and safe or you have any doubts DO NOT USE IT.

 Hold the special filter firmly over both your eyes before looking up at the Sun, and don’t remove it until AFTER looking away. The Sun should look quite dim and the sky should be completely black- if this is not the case then DO NOT USE THE FILTER.

 

#DO not look at the Sun through any optical instrument, e.g. telescope, binoculars or camera (even if you are using special filters).

 #DO NOT  view the Sun through Sunglasses, or filters made of photographic film, photographic filters, crossed polarisers, gelatin filters, compact disks or smoked glass.

#DO make sure that children are supervised at all times.

 

 All observations of objects in the sky that are located in the general direction of the Sun are DANGEROUS! Precautions must be taken to avoid damaging eyesight!

 

If you are within the zone of totality during any solar eclipse the moon will completely cover the Sun’s brilliant disk. Only then it is SAFE to view the totality eclipsed Sun directly WITHOUT any filter and admire the faint and beautiful corona: the Sun’s pearly-white outer atmosphere.

 But DO be alert to the reappearance of the Sun’s brilliant disk at the end of the total phase. As soon as the first light of the Sun has reappeared, producing a spectacular ‘diamond ring’, you MUST LOOK AWAY IMMEDIATELY and use the special filters once more.

 Viewing the Sun is dangerous. Those doing so do it at their own risk. The authors of this code and their employees do not accept any liability for any injury that may arise.
