Calculating the Magnification of a Telescope 32

For example, if the telescope objective has a focal length of 2000 millimeters and the eyepiece has a focal length of 4 millimeters, H/h = 2000/4 = 500, so the image h has been magnified by 500 times. The quantity F/f is the magnification. Problem 1 – The table below gives the optical data for some large telescopes. Use this data

The Newton reflector - Telescope Optics

The Newton reflector. The most popular telescope design among amateurs - Newtonian reflector - consists from a single concave primary mirror and a reflecting flat. It is a single optical surface of the primary mirror that creates the image, while the flat merely directs light out to the side, to an accessible observing location.

What is a Cassegrain telescope? A Cassegrain telescope (proposed by Laurent Cassegrain in 1672) uses a primary parabolic mirror and a secondary hyperbolic mirror to reflect the light to the primary through a hole.The secondary mirror produces a diverging and folding effect creating a telescope having a short tube length with a long focal length.

Aberrations of the Newtonian reflector diagonal flat

Fast Newtonian telescopes usually have the flat "offset", or slightly shifted from the strictly centered position away from the focuser and toward the mirror, both directions by ∆=(D-V)/4[F-(1/16F)]D, in units of the diagonal flat's minor axis, where D and V are the aperture diameter and fully illuminated image field diameter, respectively, F ...

Reflecting Telescopes use a concave primary mirror to collect light and form an image. In the Newtonian type of reflector, light is reflected by a small, flat secondary mirror to the side of the main tube for observation of the image. In the refracting telescope, light is collected by a 2-element objective lens and brought to a focus at F.

The reflector telescope was first conceived by Sir Isaac Newton (hence "newt" in Newtonian), who first conceived of the idea that mirrors can be used to create a magnified image in the same way that a lens could. Newtonians are some of the most commonly sought after telescopes for their simple design and incredible light gathering capability.

Hint: Reflecting telescope is one that was constructed by Newton. This telescope as the name suggests uses the principle of reflection also, so must consist of a reflecting mirror. Students must draw a well labeled clear diagram for the telescope and then explain its working firstly. Afterward, compare it with other refracting telescopes.

A Beginner's Guide to Collimation - Gary Seronik

Just kidding! I wanted to see if you were paying attention. Collimation is a 3-step process. Step #1 is to roughly align the primary mirror. Step #2 is to position the secondary mirror. Finally, step #3 is to fine-tune the alignment of the primary. Most nights, step #3 is the only one you'll have to perform.
