Transit of Venus
Monday, June 04, 2012
A couple of friends asked me to put together some resources
about the Transit of Venus...
So,
I have decided to make a post about everything I have found to be useful
on the Transit of Venus that will happen on June 5 and 6.
You can check where the planets are at this very moment,
just click here.
On June 5 and 6 Venus will pass between us and the Sun.
This is the last time it will happen in the 21th century.
The next time Venus passes in front of the Sun will be in 2117.
In our life time we had the chance to see it in 2004 and we can still catch it tomorrow!

"Acceptable filters
for unaided visual solar observations include aluminized Mylar. Some
astronomy dealers carry Mylar filter material specially designed for
solar observing. Also acceptable is shade 13 or 14 arc-welder's glass,
which is available for just a few of dollars at welding supply shops.
Unacceptable filters
include sunglasses, old color film negatives, photographic
neutral-density filters, and polarizing filters. Although these
materials have very low visible-light transmittance levels, they
transmit an unacceptably high level of near-infrared radiation that can
cause a thermal retinal burn. The
fact that the sun appears dim, or that you feel no discomfort when
looking at the sun through the filter, is no guarantee that your eyes
are safe. "★ Photographing the Sun

Always use a proper filter when observing or photographing the sun.
Regular sunglasses and photographic polarizing or neutral-density (ND) filters are not safe for use on the sun, you can burn your eyes and your camera'simage sensor!
#14 Welder's glass (but you will see it all in green)
and eclipse glasses are best for people
who won't photograph the Sun.
If you plan on taking pictures you need a Solar filter,
such as a Baader, Thousand Oaks, Meade,
I will be using a Meade Solar Filter film/sheet that I have cut
and placed on top of a UV filter for my telephoto lens.
I removed the ring that kept the glass in the filter
and added the film on it and locked it in place.
Then all I have to do is put the filter on my lens as usual and take a picture.
An Mylar filter like the Meade film I am using takes a picture of the
Sun like this:
I was testing the filter and didn't use a tripod, so I shake.
The photo will have a much better quality when you use a tripod and
a remote shutter trigger.
