PRIMARY MIRROR ADJUSTMENT
If the reflection of the secondary mirror does
not appear to be in the center of your view:
1. Loosen the 3 primary mirror lock screws a
couple of turns each (Figure 8).
2. Turn the 3 primary mirror adjustment screws
until the reflection of the secondary mirror
is centered in the view.
3. Gently tighten the locking screws. Your
telescope is now collimated.
CLEANING AND MAINTENANCE
Cleaning should be done as little as possible
and then only with mild soap solution and
a soft, lint-free cloth. Do not rub elements
when cleaning. Blot optical components
gently and allow telescope to air-dry.
Store telescope in its box or in a telescope
case when not in use. Do not use pure alcohol
or solvents to clean any parts of the telescope.
Do not remove optical elements from the
telescope as doing so may affect the alignment
of optical components when reassembled. If
the telescope needs realignment, contact us at
1-800-728-6999 for further direction
1. Brush telescope optics with camelhair brush
or blow off dust with an ear syringe (can be
purchased at any pharmacy). Do not use a
commercial photographic lens cleaner.
2. Remove organic materials (e.g. fingerprints)
with short gentle strokes using soft white
tissue paper and a solution of three parts
distilled water and one part isopropyl alcohol.
You may also add one drop of biodegradable
dish soap to one pint of the homemade
solution. Do not use lotioned or scented
tissues as they could damage the optics of
your telescope.
3. Wipe down the outside of your telescope
with a dry cloth or let air dry inside to remove
condensation prior to packing up your
telescope. Do not wipe any of the optical
surfaces. Instead, allow the optics to dry
naturally in warm indoor air prior to packing
up your telescope.
4. Protect your telescope from excessive heat.
For example, do not store your telescope in a
sealed car on a warm day. Excessive storage
temperatures can damage your telescope.
