Aligning the Secondary Mirror
Only the secondary mirror can be adjusted on the TableTop.
If the secondary mirror seems off center, or the star test as
described above is showing an elliptical or off center diffrac-
tion pattern you may need to adjust the tilt of the mirror using
the three allen-head screws on the secondary holder.
Appendix B:
Cleaning the Optics
Cleaning Lenses
Any quality optical lens cleaning tissue and optical lens clean-
ing fluid specifically designed for multi-coated optics can be
used to clean the exposed lenses of your eyepieces. Never
use regular glass cleaner or cleaning fluid designed for eye-
glasses.
Before cleaning with fluid and tissue, blow any loose particles
off the lens with a blower bulb or compressed air. Then apply
some cleaning fluid to a tissue, never directly on the optics.
Wipe the lens gently in a circular motion, then remove any
excess fluid with a fresh lens tissue. Oily fingerprints and
smudges may be removed using this method. Use caution;
rubbing too hard may scratch the lens. On larger lenses, clean
only a small area at a time, using a fresh lens tissue on each
area. Never reuse tissues.
Cleaning Mirrors
You should not have to clean the telescope’s mirror very often.
Covering the telescope with the dust cap when it is not in
use will help prevent dust from accumulating on the mirrors.
However, when bringing the telescope inside after an eve-
ning’s viewing it is normal for moisture to accumulate on the
mirror due to the change in temperature. We suggest leaving
it uncovered overnight to allow this condensation to evapo-
rate. Improper cleaning can scratch mirror coatings, so the
fewer times you have to clean the mirrors, the better. Small
specks of dust or flecks of paint have virtually no effect on the
visual performance.
If either mirror needs cleaning please email us at:
