A telescope must grasp the light from enormous distances. A microscope's task is to refine tiny images at very close distances.
Reflecting telescope. Most useful reflectors are compound types, combining a system of mirrors and lenses, such as the Newtonian and Cassegrain.
Hi , A reflective scope uses mirrors to focus the image and the light while a refractive scope uses curved glass lenses to focus the light and the image. Generally the reflector telescope is better for deep sky viewing and the refractor is better for lunar and planetary viewing. You can also find a compound telescope which uses both glass and mirrors which is better for general viewing.

compass, thermometer. telescope, and the compound microscope :)(hope it helps)
Multiply the magnification or power of the objective lens times the power of the eyepiece and it equals the total magnification
Zacharias Janssen was the first person to invent the microscope and the kind of microscope he made was a compound microscope--a microscope that uses two or more sets of lenses. Plus, the first compound microscope (by Zacharias) was made around 1595 in Middleburg, Holland.
A compound light microscope is used to magnify objects in steps.
objective lens
The objective and the eyepiece.
LPO
The upper part of a compound microscope that holds the objective lens
Don't crush the slide with the objective lens.
A microscope with more than one lense, has an objective and an eyepiece.
The type of microscope that you are looking for is known as a "compound microscope."A pair of lenses includes the objective lens (one or more) and the eyepiece lens.

what magnification is ontained with the high power objective
A low power objective in a microscope is a Small Lens with Low Magnifying Power. A microscope head with two eyepiece lenses, one for each eye. Generally this term is used in describing a high power (compound) microscope. With a low power microscope we say "stereo" head because, unlike the compound microscope, the stereo has a separate objective lens for each eyepiece lens, producing two independent paths of light, one for each eye. In the compound microscope with a binocular head, there are two eyepiece lenses but still only one objective lens and you will not get stereo vision. Hope this helps.
