Buying your 1st Orion Telescope
With so many planetary telescope manufacturers on the market, we need to make sure we buy a planetary telescope which meets our needs. First step to choosing a planetary telescope, is to look at what we want to achieve with the planetary telescope. This is crucial as it will allow us to buy the best planetary telescope for our needs.
If you are buying your first astronomy telescope, then buying a planetary telescope is not always easy, though almost all of Orion telescopes are great for viewing the heavens, some may not be practical to your needs. I have included just below some questions for you to consider before buying your first astronomy telescope, they will help you well in picking a planetary telescope which meets your needs.
Here are some questions to consider, when looking to buy an Orion planetary telescope to look at space objects:
* Do you simply want the planetary telescope for show?
* How much space do your really have to hold the planetary telescope?
* Do you only want to look at the moon and planets within our solar system?
* Do you want to explore deep space objects such as galaxies and nebula?
::: How To Buy A Space telescope :::
Orion telescopes come in many different models, and types. So it is best to look at would you prefer your Orion telescopes to simply be able to look at local objects, such as planets and the moon or would you want to look at deep space objects. This is crucial as most cheaper planetary telescope models may not be up to the job of being able to view distant nebula.
I have found that Orion refracting planet telescopes are great to hold as show planet telescopes, where you have a great design, and want it to complement your home. A refracting planetary telescope also is great for looking at the planets in our solar system, and the moon.
For deep space objects, my planetary telescope of choice is reflecting Orion telescopes. These planet telescopes house a mirror, and are great for deep space astronomy. How a Orion reflecting planetary telescope works, is by having light bounce off a mirror at the back of the planetary telescope, then zoom back up the tube to meet a mirror, which reflects the light to the side of the tube, where the eyepiece is.
The mirror size on a reflecting planetary telescope is what determines the power of the planetary telescope, and how far you can see. Many people new to astronomy think that magnification is key to a planetary telescope, however that is not the case. You can magnify any object in the sky to a large amount, however, whether you can see any detail is a different matter. So, if you find a camera shop or normal consumer electrical shops trying to sell you a planetary telescope based on its magnification, look elsewhere!
I like Orion planet telescopes as they are made for people who want the planetary telescope to do what they want. The Orion planetary telescope is competitively priced, and has good features. The tripod of the Orion planetary telescope are a key ingredient in having a great time viewing the heavens. And Orion planetary telescopes provide a stable tripod.
Orion telescopes are not as popular as Meade telescopes, however, I have found that you can get a better planetary telescope for the same price as a Meade planetary telescope. If you want a planetary telescope to provide you breathtaking views of the heavens, then a Orion planetary telescope may be what you are looking for.
What are the types of telescopes and Cameras?
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.

I actually only use binoculars! It is too cloudy here!
