Why doesn't the telescope mirror in a reflecting telescope get in the way of what you are viewing?
It does, a little. But the amount of light lost by the secondary mirror blocking the primary mirror is generally a small percentage. But to avoid even that loss, some reflecting telescopes are being built with an angled primary mirror. The secondary mirror is off-axis, meaning that the secondary mirror doesn't block ANY light from the primary.
Which design has a convex primary mirror and a flat secondary mirror with the eyepiece located on the top side of the telescope tube?
The Newtonian reflector has a convex primary mirror and a flat secondary mirror with the eyepiece located on the top side of the telescope tube.
Is hubble space telescope a convex?
No - HSTs' primary mirror is a Cassegrain Reflector of Ritchey-Chrétien design, which contains a hyperbolic primary/secondary mirror.
Which part of a refracting telescope forms the image?
Eyepiece, Primary Mirror, Secondary Mirror, Prime Focus.
What telescope has an eyepiece lens and a mirror?
The telescope described is an optical telescope. If the primary optic is a mirror, it's a reflector, and it the primary optic is a lens, it's a refractor.
What kind of shape is the primary mirror of a reflecting telescope?
The name of this type of instrument is derived from the fact that the primary mirror reflects the light back to a focus instead of refracting it. The primary mirror usually has a concave spherical or parabolic shape, and, as it reflects the light, it inverts the image at the focal plane.
How big is the Hubble space telescope primary mirror?
7
How many centimeters is the diameter of the Hubble telescope's mirror?
The primary mirror of the HST has a diameter of 2.4 m; the secondary mirror measures 30 cm in diameter.
What reflecting telescope has a focus which results from a single secondary mirror and which forms through a hole in the primary mirror?
are you doing your science homework?
Are light-gathering power and resolving power determined by the primary mirror of a telescope?
Yes, both have to do with the diameter of the objective mirror/lens
Is a Hubble space telescope a space telescope?
No, it isn't. The Hubble Space Telescope is a reflector. It has a primary mirror, and not a primary lens.
What type is the the hubble space telescope?
HST's primary mirror is a Cassegrain Reflector.
