Im sorry but you need to elaborate by editing this question by stateing what is unusual for a telescope to do.
Telescope eyepieces are important of any visual telescope. It is the main part of the telescope and is what determines how the object will look like through the telescope.
simplest possible telescope
The focal length of a telescope is directly related to the magnification in that the longer the focal length, the more magnification you get from the telsceope. How the focal length of a telescope relates to the length of the telescope itself depends on the design of the telescope. In a refracting telescope, the focal length is approximately the length of the telescope. In a reflecting telescope, the focal length is roughly two time the length of the telescope.
The most powerful telescope is the Hubble telescope, please note you did not ask where.
She didn't invent the telescope, but she used a telescope to discover a comet.
Tremble Island (Turret Rock) and the Large Zenith Telescope,
Perhaps there is an optical blemish in your telescope causing you to see what looks like a line in space. Try looking at a streetlight in the distance with a similar brightness to see if it is still there. If you are convinced you are seeing something unusual, call any local telescope club or university astronomy department and tell them what you are seeing.

Telescope.
it is a reflector telescope
The Hubble Space Telescope has a number of instruments, but the primary one is an optical telescope.
No. A Dutchman created a refractive telescope. Newton improved the telescope by creating the Reflective Telescope.
