What do telescopes allow you to see?

Posted in Telescopes on May 29th, 2010 by admin

I know Telescopes allow you to see the moon and images of certain planets, but does it actually allow you to see in depth detail of star clusters etc.?

I would apprectiate experienced opinions please.

Stars are points of light. A telescope might let you see some color.

Detail can be seen on the Moon, nebulae, some galaxies. Open clusters become lots of dots. Globular clusters can become lots and lots of dots. Many stars become double and triple stars.

Venus shows a crescent. Mars shows polar caps and certain large features. Jupiter has bands, swirls, the GRS, and moons. Saturn has rings, some bands, and moons. Uranus shows a colored disk, as does Neptune. Pluto is a dot.

There may be heavenly views through a neighbor’s window. The Earth is generally close enough to touch.

What college major should I go into besides astronomy, if I love space?

Posted in Astronomy on May 29th, 2010 by admin

I have always been obsessed with anything that has to do with space. Looks like you need to know physics, calculus, etc to get a degree in Astronomy. Is there any other option for me?

Engineering physics or Aerospace engineering. However, if you really want to understand space; you need Multilinear Algebra. So you understand, mapping points to themselves in 4d space.

Do you know of any best telescopes for land viewing ?

Posted in Telescopes on May 18th, 2010 by admin

Any best "terrestrial" Telescopes ? To look high up into the mountains into the woods with at birds? The view of them be 100 yards away. So many interesting animals to see. And Binocular’s won’t do.

Are there any available for under $600.00 US or as near as possible. Or Would a a monoscope do for less?

Thanks in advance.

How to Use Telescopes : How to Align Telescopes on Equatorial Mounts

Posted in Telescopes on May 15th, 2010 by admin

Telescopes should be aligned on equatorial mounts, often centering on the North Star, to ease following celestial bodies over time. Align Schmidt-Cassegrain telescopes with an observatory director in this free astronomy video.

What are the types of telescopes and Cameras?

Posted in Telescopes on May 11th, 2010 by admin

i would like it in terms of science, refracting Telescopes.etc.
What are the advantages and disadvantages of each one of them.
A website would be helpfull

From Answers.com:
Optical telescopes
Three main types of optical telescopes – and these are divided into subgroups. They all have their different advantages and disadvantages and they are used in different areas of Astronomy.

Refractor telescopes (Dioptrics)

* Non-achromatic
o Galilean telescope
+ Galileoscope
o Keplerian Telescope
+ Aerial telescope
* Achromatic telescope
* Apochromatic
* Superachromat
* Varifocal gas-lens telescope

Reflector telescopes (Catoptrics)

* Newtonian telescope
o Dobsonian telescope
* Gregorian telescope
* Cassegrain telescope
o Ritchey-Chrétien telescope
o Dall-Kirkham
* Large liquid mirror telescope
* Pfund telescope
* Schiefspiegler telescope
* Toroidal reflector / Yolo telescope
* Herrig telescope
* Stevick-Paul telescope

Combined Lens-Mirror Systems (Catadioptrics)

* Schmidt camera
* Schmidt-Newton telescope
* Schmidt-Cassegrain telescope
* Lurie Houghton
* Maksutov telescope
* Modified Dall-Kirkham telescope
* Klevtsov-Cassegrain
* Argunov Cassegrain telescope
My favorite is the Catadioptric Newtonian Telescopes.

What are some careers in Astronomy, and what classes should I take for it in college?

Posted in Astronomy on May 11th, 2010 by admin

I got very interested in Astronomy (while looking at the meteor shower) so I started thinking about astronomy as a career option, but I want to know what classes I should take in my last 2 years of High School and also later for college. I mainly want to know about what college classes I should take.

There really aren’t any careers in Astronomy if you don’t have a PhD, so you’re going to be in college for a long time. Take all the math and science you can while in high school – it would really help if you could take calculus your senior year so you can start calculus-based physics your first semester of college. You’d want to major in physics in college, take classes in math, computer science, and astronomy, and spend your summers doing research projects with professors to prepare for graduate school and a job doing astronomy. Grad school is another 4-8 years after the bachelors.
