3.
Lock the R.A. and DEC clamps to hold the telescope in place.
4.
Check the finder to see where the object is located in the field of view.
5.
Adjust the screws on the finder bracket, tightening one while loosening another, until cross hairs are
centered on the target.
6.
Tighten each set screw a quarter of a turn to ensure that they will not come loose easily.
The image orientation, through the finder scope is inverted (i.e., upside down and reversed from left-to-
right). Because of this, it may take a few minutes to familiarize yourself with the directional change each
screw has on the finder.
With the telescope fully assembled and all the accessories attached, you are ready for your first look. Your
first look should be done in the daytime when it is easier to locate the locking clamps and slow motion
knobs. This will help to familiarize you with your Ultima, thus making it easier to use at night.
As mentioned in the introduction, your Celestron Ultima telescope works well as a terrestrial spotting scope.
When not used to examine objects in the night sky, it can be used to study objects here on Earth.
WARNING !
NEVER POINT YOUR TELESCOPE AT THE SUN UNLESS YOU HAVE THE
PROPER SOLAR FILTER. PERMANENT AND IRREVERSIBLE EYE DAMAGE MAY RESULT AS
WELL AS DAMAGE TO YOUR TELESCOPE.
1.
Find a distant object that is fairly bright.
2.
Insert a low power eyepiece (one with a large focal length 30mm) into the telescope.
3.
Release the R.A. and DEC clamps and point the telescope in the direction of the object you selected.
4.
Locate the object in your finder.
5.
Move the telescope by hand until the object is centered in the finder.
6.
Lock the R.A. and DEC clamps to hold the telescope in place.
7.
Look through the main optics and the object will be there (if you aligned the finder first).
8.
Use the slow motion knobs to center the object if needed. Remember, you should not use the drive for
terrestrial viewing.
Try using different eyepieces to see how the field changes with various magnifications.
Looking at objects in the sky is quite different than looking at objects on Earth. For example, many objects
seen in the daytime are easy to see with the naked eye and can be located in the telescope by using
landmarks. In the night sky, many objects are not visible to the naked eye. To make things easier, you are
better off starting with a bright object like the Moon or one of the planets. Here is a quick description to get
you started. A more detailed description is found under the section on "Visual Observing."
