Care & Maintenance; Additional Precautions - Takahashi FOA-60Q Instruction Manual

▼Optical Axis
Before shipment, the optical axis of your
telescope has been precisely adjusted
and in normal use it should not require
adjustment. On occasion, however,
d a m a g e o r r o u g h h a n d l i n g d u r i n g
transport may cause alignment issues.
If there is an abnormal star image visible
with your telescope, immediately contact
your local distributor.
▼Care for the Lens
If the front lens of the objective has dust
or dirt particles on it, use a large hand-
powered blower to remove the particles.
Under no circumstances should dust be
removed by any other means. Rubbing
the surface will cause scratches. If the
lens must be cleaned, be certain that all
dust and particles have been removed by
using a blower.
▼Minimize large fluctuation in temperature
a r o u n d y o u r t e l e s c o p e . W h e n t h e
telescope is brought out from a warm
room to colder air, dew may form.
▼ S t o r e t h e t e l e s c o p e i n a c o l d d r y
environment. Any dew should be removed
by blowing it with a hair dryer with the
heat element turned off, which means the
air will be at room temperature. This flow
of room temperature air will dry the dew
and not leave a residue. Additionally, it is
a good idea to store the telescope with a
drying agent near the objective to prevent
moisture issues.
Care & Maintenance

Additional Precautions

T h e n u s i n g c o t t o n s w a b s s l i g h t l y
moistened with telescope lens cleaner,
dab the surface, changing cotton swabs
often until the objective is cleaned.
If any questions arise during this process,
immediately contact your local distributor
for help. Under no circumstances should
the surface ever be rubbed.
REMEMBER, DO NOT USE ANY FORM
OF CANNED AIR TO REMOVE THE
PARTICLES.
Canned air is very cold and could harm
the front lens of the objective. Be certain
that the dew cap is removed before
attempting to clean the objective. Use
the procedure above, if the front and rear
surfaces of the objective must be cleaned.
NEVER USE ALCOHOL TO CLEAN
THE LENS. IT WILL DESTROY THE
COATING.
▼Under no circumstances should the
lenses be disassembled. The lenses have
been properly aligned and set in place by
a skilled optical technician with special
tools. Movement, removal or disassembly
of the lenses will void any warranty on the
tube assembly.
