Magnification Table; Microscope Operation - Celestron 44320 Instruction Manual

Use the following table to determine the magnification of the different eyepiece/objective lens combination of your microscope.
1. Take the Styrofoam container out of the carton.
2. Remove the tape from the Styrofoam container holding the various parts in place.
3. Carefully remove the microscope and other parts from the container and set them on a table, desk, or other flat surface.
4. Remove the plastic bag covering the microscope.
5. Remove the plastic cap from the zoom eyepiece (1).
6. Install the batteries in the top illuminator (11) which uses two AAA batteries (user supplied). See the image below (figure 2) --- Turn the top of the pen light
(top illuminator) counterclockwise to take it off. Then, insert the AAA batteries into the tube with the positive ends going into the tube first. Screw the top
of the pen light clockwise until tight.
7. Install the batteries for the bottom illuminator in the base (7) of the microscope which uses two AA batteries (user supplied). See the image below (3a)
showing the battery compartment closed at the back of the microscope. Then, image 3b shows the batteries being installed in the compartment (see the
inside of the battery compartment door to see where the positive (+) and negative (-) ends of the batteries go. Pull out on the door to open it while holding
the base firmly and push firmly to close it after the batteries are installed.
You are now ready to use your microscope for looking at specimen slides or small objects through the zoom eyepiece! For using the digital (CMOS) camera,
installation and operating instructions will follow later in this manual.
Viewing a Specimen
Carefully place a specimen slide under the stage clips (9) and center the specimen directly over the hole in the center of the stage (5) – Figure 4a below shows the stage
area with the hole in the center and Figure 4b shows a specimen slide centered over the hole in the stage. It will take some experimenting to place slides or objects in the
center of the stage as the image you see is upside down and reversed but after some usage you will have an easy time centering. Read the sections below on Focusing,
Changing Power, and Illumination before proceeding.
You are now ready to focus and view the specimen, but first you must take some precautions so as not to damage a specimen slide or valuable object. When using the
higher powers while you are focusing, make sure that the objective lens does not hit the slide or object being viewed.
Focusing & Changing Power (Magnification)
Now that the specimen slide (or object) is placed directly under the objective lens, use the focus knob (8) to focus on the specimen.
Note that for very small objects, you should set them on the clear slide with a recessed hold in the center.
1. Always start with the lowest power (4x objective lens) and have the zoom eyepiece at the 10x position (all the way
counterclockwise ((when you are facing the microscope from the front)) until it stops) so that the total power is 40x – this is the
most useful power for solid objects.
