Please USE CAUTION when viewing or photographing the sun
On Friday afternoon on April 8, 2005, Most of the USA will be honored by a partial solar eclipse.
WARNING: DO NOT EVER LOOK AT THE SUN directly,
especially with magnification(telescope or camera), without using
appropriate filtering. This would be a good,
undamaged solar filter for binoculars or telescopes,
solar sunglasses or welder's glass (see detail at end
of note), or use an indirect means of observing such
as image projection (also described at end).
The sun's appearance will only have a small bite out
of it. (Picture a very fat crescent moon shape.)
There will only be a very slight darkening of the sky
due to this partial eclipse in Houston, would not be
noticed.
Projections of the sun's modified disk should be
visible where light travels through pinholes
inheaves or a piece of paper, but the affect is
slight.
Welder's Glass Instructions: After checking out the
equations related to welder's glass, and
recommendations from the experts, you need to use
Number 14 Welder's Glass. Do NOT use anything less!
My personal experience in buying welder's glass is
that it doesn't often come that strong, so you may
need to use more than one piece. If you have to use
more than one piece of glass, to get the filtering
you need, add 1 to the total for each piece of glass
over 1. So for example, if you need to use two
pieces of welder's glass, then they should total 15.
Three should total 16.
Image projection: Do not let unfiltered sunlight
pass
through a larger telescope. It can cause severe
damage due to overheating (essentially what it can do
to your eyes). You can use a very small
telescope, or make the equivalent of a pinhole
camera. In either case do not look at the sun
directly. NOT through the telescope and NOT through
the pinhole. Remember this is PROJECTION. You need
a white sheet of papere to project onto. On another
sheet of paper, cut a hole. Cover the hole with
aluminum foil, and then put a tiny pinhole in the
center of the foil. Hold the pinholed sheet a few
feet from the unholed sheet in the direction of the
sun. You should see a project of the sun's disk.
You can even see sunspots this way. This same effect
can sometimes be seen when sunlight filters through a
tree with leaves.
Good luck, may you have successful and SAFE viewing.
I can NOT stress enough to use proper protection when viewing or photographing the sun. It WILL damage your equipment and your EYES
