Who
said you have to be in the dark to do astronomy! Turning your
telescope to the Sun is fun and educational. Watch the march
of giant sunspots, the clouds of glowing vapor in the photosphere,
and solar “granulation” detail. But be sure to
protect your precious vision with a safe Astro Solar Safety
film Filter! Looking at the Sun without one, even for an instant,
can permanently damage your eyes.
Specially
CE-tested safety film with high quality optical characteristics
reduces intensity of sun light by 99.999%.
Astro
Solar safety
film
is a
|
specially manufactured streak and blister free foil only 0.012mm thick
and attains the optical quality of plane parallel glass filters. The
base material is not Mylar. The highly uniform molecular structure
of this material is the result in nuclear elementary particle physics.
The coating is subject to constant quality control. It’s reflective
property of over 99.999% has been the German Republic Bureau of Standards
and Conformity with EU norm 89/686 is certified with CE symbol. It
reduces the intensity of sun light by factor of over 100,000. Coating
on both sides of the foil ensures a highy uniform filtering. While
neutralising the occasional microscopic holes in the coating (which
are also much more present n glass filters). One layer of this foil
is sufficient for the construction of a safe, high resolution solar
filter. The quality of the solar image is immeasurable, better than
what can be achieved by using a so-called Mylar “rescue blankets”
or similar materials, which must be used in several layers.
Base Astro - Solar is extremely clear and homogenous. It is specially
treated 1) To absorb internal reflections (reducing
haziness present in other films).
2) To reduce internal stresses which dramatically
improve the optical performance over Mylar and similar filters.
3) Gives neutral white image of the Sun without any
color, against a black background sky.
Astro-Solar filter is a very flexible substance by nature. When mounted
in the filter cell, it will be quite wrinkled. Don’t be upset
by the appearance because the best resolution is obtained when the
material is slightly relaxed or wrinkled.
