Using binoculars, I saw a huge sunspot at sunrise this morning, which
for me was right after 6:00 a.m. outside Washington, DC. It looked
like the transit of Venus. Really, it was that large and noticeable.
The atmosphere was so humidity-laden that I could look at the sun
through the binoculars without any needing any glass from a welder's
mask. YMMV.
I hope you realize that amongst the rods and cones on your retina, there are
NO pain receptors.
It is really easy to damage your retina and not realize it -- and looking
through a telescope or binoculars without a solar filter (not depending on
clouds) can quickly cause serious damage.
NEVER look at the sun without a solar filter. Do NOT depend on clouds or fog.
Oh, did I mention NEVER?
That was why during the eclipse of 1970, everyone was told the safest
method was to pit a tiny hole in a box and watch the projection against
the other side.
