It all depends on what one is doing with the telescope. To gaze at the sun, the eyepiece is not used and in astrophotography, the eyepiece may be used but not always.
It would be 50x. To find the magnification, you just have to multiply the number eyepiece and the number objective. So for example, * A 10x eyepiece and a 40x objective would have a magnification of 400x * A 10x eyepiece and a 100x objective would have a magnification of 1,000x
That depends on the eyepiece, a 9mm eyepiece will have more magnification than a 22mm eyepiece.
Lint-free cloth would be suitable.
it is the cylindrical structure which is used to support the eyepiece. it is the cylindrical structure which is used to support the eyepiece.
You are referring to Ramsden eyepiece. This is a particular lens used in optical microscopes.
The eyepiece is primarily used to examine micro-organisms as well as viruses that are undetected by the human eye.
used to focus the image
it is something on a microscope used for the eyepiece
Concave lenses are used in the eyepieces of microscopes. However, they are not used alone on the eyepiece, but are joined in a concave-convex combination to prevent internal reflections.
the diameter of the eyepiece, the diameter of the objective, the focal length of the eyepiece or the number of mirrors used to form the image?
Eyepiece is a noun.
multiply the magnification of the eyepiece by the magnification of the high objective lens. for example, if the eyepiece magnifies x10, and the high objective magnifies x40, then the total magnification would be 400x
