Star Hopping; Care And Cleaning Of The Telescope - Celestron AstroMaster AZ Serie Manual De Instrucciones

STAR HOPPING

The easiest way to find your way around the sky is by a technique called star hopping The first thing you will need to do is
measure the field of view of your finderscope Look in the sky and locate a constellation with bright stars You can use your
planisphere or astronomy app to help identify it Now find the map in your star atlas that shows this constellation Center your
finderscope on any bright star that you can recognize on the star map Hold your head 12 inches behind the reflective window
of your StarPointer finderscope and move the telescope so that the bright star is at the edge of the field if view of the window
(it does not matter which direction you pick) Without moving the telescope, look through the finderscope window and locate
another star near the opposite edge of the field of view Locate this second star on the chart Measure the distance between
these two stars on the chart using a ruler This distance is represents one finderscope field of view on your atlas You can now
use this measurement to locate celestial objects

CARE AND CLEANING OF THE TELESCOPE

While your telescope requires little maintenance, there are a few things to remember that will ensure your telescope
performs at its best Occasionally, dust and/or moisture may build up on the objective lens Special care should be taken
when cleaning any instrument so as not to damage the optics
If dust has built up on the optics, follow these steps, in order, to clean your scope:
1 . Use a camel hair brush to gently remove the larger particles
2 . Use a photographer's squeeze bulb to blow away any loose debris You can also use a can of compressed air, such as those
sold for cleaning computer keyboards, but you need to be careful Avoid using cans that are almost empty and be sure to hold
the air can vertically Failure to do this can result in the can spitting propellant out onto the optics Hold the optical surface at
an angle to the spray from the can for approximately two to four seconds
3 . Use an optical cleaning solution of over-the-counter isopropyl alcohol and distilled water in a 50/50 mixture Apply this solution
to a white unscented tissue, then apply the tissue paper to the optics Low pressure strokes should go from the center of the
lens (or mirror) to the outer portion in straight lines like spokes on a wheel Do not rub in circles!
You may experience dew build-up on the optics of your telescope during an observing session If you want to continue
observing, the dew must be removed, either with a hair dryer (on low setting) or by pointing the telescope at the ground
until the dew has evaporated If moisture condenses on the inside of the optics, remove the accessories from the telescope
Place the telescope in a dust-free environment and point it downward until the moisture evaporates
To minimize the need to clean your telescope, replace all lens covers once you have finished using it Since the telescope
tubes are not sealed, the covers should be placed over the openings when not in use This will prevent contaminants from
entering the tubes
Internal adjustments and cleaning should be done only by the Celestron repair department If your telescope is in need of
internal cleaning, please call the factory for a return authorization number and price quote
