7. VIEWFINDER
An eyepiece has a narrow field of view. The red dot viewfinder has a wider field
of view, which makes it easier to locate objects. Once the red dot viewfinder
is aligned to the optical tube, the red dot can be used to locate and place
objects more easily in the eyepiece of the telescope.
The viewfinder is powered by a 3V Lithium Coin battery (type CR2032) which
is included. Before using the viewfinder for the first time, remember to remove
the plastic insulator that is blocking the battery from connecting.
When it is time to replace the battery, push the left side of the viewfinder
housing. The battery compartment will slide out on the right side of the
device. Take out the battery and slide a new battery in place with the positive
side up. Then push the battery compartment back into the viewfinder and
power on the device.
To preserve battery life, don't forget to turn off the viewfinder after use.

8. HANDLING OR TRANSPORTING YOUR TELESCOPE
Handling the telescope around or transporting it to the observing site requires
careful handling.
The telescope can be transported in 2 main parts: The telescope tube and
the mount.
We suggest removing the accessories from the optical tube. Cover the
telescope tube and the eyepiece with their caps. It is also convenient to
remove the fine-adjustment control cables and counterweights.

The accessory tray should be removed to be able to transport with the 3
tripod legs closed.
The telescope can be transported in a vehicle without a problem. Padded
insulation can prevent scratches on the tube but it is not necessary. The
mirrors may go out of collimation after a bumpy ride but collimation would be
required after transportation anyway, with or without padding.
9. CLEANING YOUR TELESCOPE
While your telescope requires little maintenance, there are a few things to
remember that will ensure your telescope performs at its best.
Use a slightly damp soft cloth to clean the outside of the tube and tripod.
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
chemicals as this might ruin it. Do not let any liquid enter the telescope.
Occasionally, dust and/or moisture may build up on the objective lens of your
telescope. Special care should be taken when cleaning the instrument so as
not to damage the optics.
If dust has built upon the lens, remove it with a brush (made of camel's hair) or
with a can of pressurized air. Spray at an angle to the lens for approximately
two to four seconds. Next, use an optical cleaning solution and white tissue
paper to remove any remaining debris. Apply the solution to the tissue and
apply the tissue paper to the lens. Low-pressure strokes should go from the
center of the corrector to the outer portion. Do NOT rub in circles!
