Solar
Filters for Binocular,
Telescopes and Cameras
TYPE
2 +: Type
2 + Glass: Made
with high quality hand
selected glass coated
with our exclusive Solar
II Plus. The most durable
glass filter on the market.
Transmission is 1/1,000th
of 1% (Optical Density
5.0). Great for both
visual and photographic
use. Solar image is yellow
orange.
R-G
Solar Film: Designed
with quality
and cost
in mind,
our R-G
solar film
provides
a superior
image of
the sun
that rivals
our glass
solar filters
at a lower
price. Unlike
other solar
filter,
the R-G
solar film
will provide
a more pleasing
and natural Yellow-
Orange image
of the sun
our customers
have come
to know
and love
through
our Solar
Glass Filter
product
line. The
R-G film
will also
be available
in sheets
for those
who like
to make
their own
solar filters.

for Safety
and other
information.
Black
Polymer: This
material
is used
as a low
cost alternative
where only
low magnification
is used
such as
with binoculars,
threaded
camera filters,
eclipse
viewers
and finder
scopes.
The advantages
of this
material
is that
it is stronger
than Mylar
and other
thin film
solar filters
that are
currently
available.
The actual
filtering
properties
are protected
within the
substrate.
WHAT
SIZE filter
will fit
my telescope?:
The
I.D.
of
the
cell
slips
over
and
around
the
O.D.
of
the
telescope
tube
or
lens
holder.
Simply
choose
the
closest
outer
cell
I.D.
size
larger
than
the
outside
diameter
measurement
of
the
lens
holder.
Do
not
choose
a
size
the
same
as
your
O.D.
since
this
will
be
too
tight
and
not
allow
room
for
the
felt
lining.
Felt
tape
is
included
for
custom
fitting.
Full
aperture
versus
off-axis
(reduced
aperture)?:
For
telescopes
up
to
5" aperture,
off
axis
is
not
an
advantage.
Larger
apertures
suffer
more
from
daytime
atmospheric
turbulence.
This
turbulence
is
magnified
by
the
aperture.
Perfect
daytime
'seeing" only
occurs
about
1%
of
the
time.
Off-axis
reduces
the
aperture
and
increases
the
focal
length
thus
reducing
the
turbulent
effects.
We
recommend
off-axis
for
10" and
larger
telescopes.
The
solar
image
is
not
darker
with
reduced
aperture
as
we
allow
for
this
in
the
coating
density.
When
viewing
through
the
eyepiece,
the
field
of
view
is
not
reduced:
it
looks
the
same
as
full
aperture.
If
full
aperture
for
10"+
is
still
preferred
for
better
resolution,
it
can
be
stopped
down
using
a
simple
mask
as
conditions
dictate.
Mounting:
The
inside
of
the
cell
will
be
lined
with
felt
or
unlined
depending
on
the
telescope
brand
and
aperture.
If
your
filter
is
too
loose,
it
can
be
custom
fitted
using
felt
or
tape
on
inside
of
cell.
The
filter
should
not
fit
too
tightly
or
the
optical
surface
may
be
distorted
due
to
stress
on
the
cell. Velcro
is
also
provided
to
secure
the
Filter
to
the
Telescope
for
added
safety.
THREADED
CAMERA
FILTERS
Available
in
all
standard
sizes
from
46mm
through
82mm. Special
Order
Only. Please
contact
us.
NEBULAR
FILTERS
Enhance
your deep sky viewing with
the latest in multi-layer
coating technology. Our
filters transmit desired
wave-lengths in a very
steep slope vs. gentle
transition slopes in competitive
brands. This means better
contrast and overall performance.
Available
for 1.25" and
2" eyepieces.
Type
LP-1 (Broadband)
For slight to moderately light-polluted
areas.
Type
LP-2 (Narrowband)
For heavily light polluted areas.
Type
LP-3 (Oxygen
III) For diffuse and planetary
nebulae.
Type
LP-4 (Hydrogen
Beta) For Horse head, California
nebula and other faint nebulae.
H-ALPHA
PROMINENCE FILTERS
You
can now enjoy observing
the ever changing phenomenon
of the sun in hydrogen
alpha at the most reasonable
price. For over eighteen
years we've manufactured
the most popular white
light filters in the world.
With our white light filter,
excellent views of sunspots
and granulation are easily
seen. In H-Alpha light,
spectacular prominence
activity can be seen at
the limb. The 1.5 band-width
also yields some surface
detail including flares.
Each system comes complete
and ready to attach to
telescope. The system includes
a red pre-filter and H-alpha
filter mounted in a tilting
(fine-tuning) mechanism.
(Type 2 and 3 series filters
will not work as a pre-filter
since the 656.3 band-width
is not transmitted). H-Alpha
filters generally do not
work with Newtonians as
there is not enough focus
travel. Piggy-backing a
small refractor is recommended
since a large aperture
is not necessary for solar
observation.
When
ordering a solar or H-Alpha
filter, please specify
telescope brand, focal
length and outside diameter
measurement of telescope
tube. The cost of any filter
is based on the actual
aperture of your instrument.
The cell that the filter
is mounted in will be sized
to fit over the end of
the tube.
We
manufacture filters to
fit all brands and apertures
of optical instruments
including telescopes, binoculars,
cameras, telephoto lenses
and video cameras.
Thousands
of our filters are in use
world wide.
All
of our Solar filters and
Nebular filters are manufactured
in the U.S.A. by Thousand
Oaks Optical.
WARRANTY:
The
safety of this product
is guaranteed by ensuring
the coating has a transmission
of 0.001% or less. The
R-G solar film, 2+ Solar
Glass Filter and Black
Polymer is tested before
shipment. If
the film has arrived
damaged it will be replaced
free of charge. Do
not use any film that
shows any form of defect
described in this document.
Please contact us for
further return instructions.
All solar filters are
covered by a limited
liability warranty from
defects in material and
workmanship. This
warranty does not apply,
if in our, the product
fails to be safe due
to shipping, damage from
handling, storage, abuse
or misuse, or it has
been used or maintained
in a manner not conforming
to product’s
instructions or has
been modified in any
way.
