The resolving power of a telescope is the ability to produce an image in which objects that are close together can be seen separately.
Resolving power is sometimes expressed in terms of the inverse of the minimum angle there must be between two points in order to see them separated.
This minimum angle is proportional to (lambda/d) where d=diameter of objective

Not intended to improve, just a comment:
Think of resolution and clarity as the telescopes Dots per Inch (DPI).
Low DPI , Poor resolution = blurry TV picture
'Best' DPI= High Definition.
Personally on my LX2080 I get better resolution at lower powers of magnification than very high.
haha
Resolving power is measured in arc seconds. The formula to find this is as follows: arc seconds (x) = 11.6/(D) 11.6 is part of the formula D- is the diameter of the telescope (which you have = 25cm) Therefore the resolving power should be: 11.6/25 = .46 arc seconds
No, you can change the magnification of the telescope by simply changing the eyepiece. The two most important powers of the telescope, light-gathering power and resolving power, depend on the diameter of the telescope, but it does not control the magnification.
Resolving power / the resolution.
Mainly, it has to have a large main lens, or main mirror.
The "resolving power" of a telescope is a measure of the ability of a telescope to distinguish between two separate objects that appear to be very close together in the sky.

Yes, both have to do with the diameter of the objective mirror/lens
Earth's atmosphere does not limit a telescope's resolving power.
I know of at least three. I hope these help: - magnifying power - light gathering power - field of view
The aperture of the main lens or mirror, which also determines the light gathering power ------------------------- True but the quality of the mirrors or lenses (how near they are to a perfect shape for the design of telescope) determines the sharpness of the image.
The ability of a microscope, telescope, or other optical instrument to produce separate images of closely placed objects. It's also possible to relate this to optical instruments such as computer screens or digital cameras where a higher resolution (more resolving power) will produce a clearer image.
If magnification increases ONLY, then resolving power does not increase. However, if the magnification increased while staying in focus (upgrading resolution and magnification with objective lense), shorter wavelengths are needed to stay in focus with increased magnification to yield the same high resolution as with previous objective lense, so this case, resolving power does increase.
