Telescope Maintenance
While your StarSeeker telescope requires little maintenance,
there are a few things to remember that will ensure your tele-
scope performs at its best.
care and cleaning of the Optics
In general, your telescope's objective lens will only need to be
cleaned very infrequently, if ever. Covering the front opening of
the telescope with the dust cap when it is not in use will pre-
vent dust from accumulating on the lens surface. Keeping the
dust cap on the focuser's 1.25" opening is also a good idea.
Improper cleaning can scratch the lens coatings, so the fewer
times you have to clean the lens, the better. A little dust or
small specks of paint from the scope's interior have virtually no
effect on the visual or imaging performance of the telescope.
So avoid the urge to clean the optics unless it is absolutely
necessary!
If dust has built up on the lens surface, remove the dust with a
brush made of camel's hair or a can of pressurized air. Spray
at an angle to the lens for approximately two to four seconds.
Then, use an optical cleaning solution and optical cleaning tis-
sue to remove any remaining debris. Apply the solution to the
tissue and then apply the tissue paper to the lens. Low pres-
sure strokes should go from the center of the lens to the outer
portion. Do NOT rub in circles! You can use a commercially
made lens cleaner or mix your own. A good cleaning solution
is isopropyl alcohol mixed with distilled water. The solution
should be 60% isopropyl alcohol and 40% distilled water. Or,
liquid dish soap diluted with water (a couple of drops per one
quart of water) can be used.
collimation
For the sharpest images, the optics of your telescope should
be precisely aligned, or collimated. Your StarSeeker II 102
refractor's optics were aligned at the factory and should never
need adjustment. If you believe the scope is out of collimation,
contact Orion Customer Service at (800) 676-1343, or sup-
port@telescope.com

RS-232 connection
You can control your StarSeeker telescope with a computer via
the RS-232 port located on the computerized hand controller
using the included RS-232 serial cable. If your computer does
not have a serial port (which many do not these days), you will
also need to purchase a serial-to-USB adapter, available from
Orion. The telescope can be controlled using popular astrono-
my software programs such as Starry Night.
The RS-232 port and cable are also used for updating the
firmware of the hand controller, when firmware updates are
available. See Oriontelescopes.com for the firmware update
procedure.
This device complies with Part 15 of the FCC Rule. Opera-
tion is subject to the following two conditions: 1) This device
may not cause harmful interference, and 2) This device must
accept any interference received, including interference that
may cause undesired operations.
