It could easily cause instant blindness or serious damage to your
eyes. To view the sun, use only appropriately designed solar filters
that will reject 99.96% of the sun light and heat. Educate your family
on how to use this telescope properly during day and night time
observations. For further information please contact your local dealer.

Usage
Important Notice
The Fluorostar 110 is designed to work with both 1 1/4 inch and 2 inch diameter
eyepieces in various focal lengths, for both daytime and nighttime viewing. Because
the Fluorostar is well suited to viewing nebulae, clusters, large galaxies and comets,
we recommend the use of high quality wide angle eyepieces. The WO SWAN (72o )
and UWAN (82 o ) series eyepieces are available in a variety of focal lengths. Viewing
the moon and planets is also impressive at magnifications of 120X when seeing
conditions permit.
www.william-optics.com
Keep in mind that the atmosphere plays an important role in seeing conditions, and
only the best seeing conditions will support high power viewing. Additional power
under less than ideal seeing conditions will not result in an increase in viewable
details, and lower powered eyepieces should there be used under those conditions.
It's easiest to locate objects using low power eyepieces (20X magnification) and then
zoom in by switching to higher powered eyepieces. The largest field of view will be
seen using a 12X low power-wide field of view eyepiece. Also remember to let the
telescope reach thermal stability for optimal results. A triplet lens takes longer than
a doublet to cool down. A stable tripod or mount is recommended for optimal
viewing. This includes high quality photography tripods, and German Equatorial
mounts, which are designed for astronomical use and include precise tracking of
celestial objects. William Optics is marketing a very practical Alt-Az mount too, which
will perfectly complement any of its refractors.
The Fluorostar has been specifically designed for astrophotography; it will produce
excellent results when used with the proper equipment. Being this a high-end
astrophotography telescope, it should be mounted on a good mount. Please see our
website for examples of photos taken with these telescopes. The Accessories Chart
on page 4 provides additional details on photographic accessories for various CCD,
digital and film cameras.
Optional accessories from WO include mounting rings and plates, super high-quality
2" Quartz star diagonals, and 2" Erecting Prisms (45o and 90o ), all of which provide
for superior viewing and high quality images.
Never aim your telescope or finderscope at the Sun without proper Solar filters
installed on the front of the telescope. Doing so for even a moment may permanently
damage your vision. Proper Solar filters consist of a filters made by reputable
manufacturers, designed to fit tightly over the front of the dew shield. Solar eyepiece
filters are not considered safe, and should not be used. With proper front mounted
Solar filters, the telescope will not be harmed by viewing the Sun. Contact your
Authorized WO Dealer for further information on the brands, sizes, and prices of
proper solar filters.
P09
Crafting the Earth's Finest Astronomical Instruments
This telescope is also well suited for higher power observations with planetary
eyepieces.
To calculate the magnification of your telescope and eyepiece combination, divide
the telescope focal length in mm by the eyepiece focal length in mm.
William Optics warranty does not cover damage to the focuser due to inappropriate tension setting.
This focuser is designed to hold many pounds without problems. If nonetheless
your setup requires additional tension adjustment, please use the tension allen
screw under the focuser.
In order to avoid sagging or denting of the focuser steel reinforcement, it is
necessary to adjust tension ONLY when the drawtube is FULLY EXTENDED.
Extend the focuser drawtube to its full 93 mm as in the picture
here above before performing adjustment.
Storage and Cleaning
We suggest placing all accessories inside an airtight container with desiccative
control. Secondly, remember to store the telescope in a non-humid environment,
never leave it in a hot heated environment. If not properly stored, it may
develop mildew growth and other preventable build up.
Be particularly careful after a night observation that the lens has no dew on it
before storing the telescope away.
In case the lens surface becomes dusty, smeared, or gets fingerprints or fungus
build-up on it, first of all, remove any surface particle by using an air blower,
then carefully proceed to wiping the lens gently with a lint-free proper soft cloth.
Use a lens liquid cleaner to get the best cleaning result. Make sure you change
your cloth to a new one from time to time.
The above-mentioned indications are not necessary if you carefully protect your
telescope.
The beautiful multi-layer Dupont paint white finish of your Fluorostar 110 is not
easy to ruin. Nonetheless take care of the exterior body tube by wiping it down
with a slightly damp soft cloth from time to time. Water should be enough to do
the job. Please do not use any organic solvent on your telescope, for example
alcohol, benzene and other hazardous chemical as this might ruin it.

please contact your WO Authorized Dealer right away for details on a service
