Question about telescopes?
I'm looking at buying a telescope. Of course, the budget is a concern, so I wonder ... Anyone know what the minimum size is decent? I see them ranging from 50 mm x 450 mm to 1,100 mm x 102 mm This means nothing to me. On the other hand, I see that Dobsonian, Newton and Galileo. Assuming that these beings are trademarks: More I think are important distinctions Tri-Central Astronomical Refractor Reflector (I know what that means) Terrestrial (I know what that means, too, and not time!) And Equatorial Any idea what they mean and why I want in my telescope? Type in a hurry, as I like to buy before Thursday. (Birthday present) If I know what these things mean, then maybe you can find one you want at a price range you can afford. (The who has everything is $ 1399)
First, I think is a mistake of buying someone something so personal as a telescope without asking first. Although it may damage surprise, I recommend including the receiver in the decision making process. Some of the factors involved are age, number of knowledgeable technical limitations, physical and many more. I'll try to give some specific answers: The minimum size decent: a refractor, a 114mm reflector, but 100 mm and 150 mm respectively, would better. Dobsonian 75mm is a type of forest, like a cannon. Newtonian optical design with mirrors. Galileo is a brand not very good. Tri-Central never heard of him in 50 years in astronomy Refractor!: optical design with a reflector lens, optical design with mirrors (like Newton) vs. ground-based astronomical: first serve only for astronomy, second only serve to bird watching, etc Equatorial mounting type This probably has killed more confused than ever, so let me tell you what I like to buy: any of these, depending on budget: http://www.telescope.com/jump.jsp? itemType = CATEGORY & Itemid = 9 Finally, where to buy, not buy at a discount / department / big box store! They do not know anything about telescopes and sell rubbish. Buying from a telescope shop (look in the Yellow Pages) or online. If you ignore this advice, you're almost sure to get your loved one a piece shit! Better to delay the gift for a few days, you lose your money. But, please, PLEASE, pay attention to my initial advice to include beneficiaries in the process decision-making.

Choosing and Using a Refracting Telescope (Patrick Moore's Practical Astronomy Series)
List Price: |
DescriptionChoosing and Using a Refracting Telescope has been written for the many amateur astronomers who already own, or are intending to purchase, a refracting telescope â perhaps to complement their existing arsenal of larger reflecting telescopes â or for the specialist who requires a particular refractor for serious astronomical applications or nature studies. Four hundred year ago, during the winter of 1609, a relatively unknown Italian scientist, Galileo Galilei designed a spyglass with two crude lenses and turned it skyward. Since then, refractors have retained their dominance over all types of reflector in studies of the Moon, planets and double stars because of the precision of their optics and lack of a central obstruction in the optical path, which causes diffraction effects in all commercially-made reflectors. Most mature amateur astronomers got started with a 60mm refractor, or something similar. Thirty years ago, there was little choice available to the hobbyist, but in the last decade long focus crown-flint achromats have moved aside for some exquisitely crafted apochromatic designs offered by leading commercial manufacturers. There has been a huge increase in the popularity of these telescopes in the last few years, led by a significant increase in the number of companies (particularly, William Optics, Orion USA, StellarVue, SkyWatcher and AstroTech) who are now heavily marketing refractors in the amateur astronomical magazines. In Choosing and Using a Refracting Telescope, well-known observer and astronomy writer Neil English celebrates the remarkable history and evolution of the refracting telescope and looks in detail at the instruments, their development and their use. A major feature of this book is the way it compares not only different classes of refractor, but also telescopes of each class that are sold by various commercial manufacturers. The author is perhaps uniquely placed to do this, having used and tested literally hundreds of different refracting telescopes over three decades. Because it includes many diverse subjects such as imaging with consumer-level digital cameras, imaging with webcams, and imaging with astronomical CCD cameras â that are not covered together in equal depth in any other single volume â Choosing and Using a Refracting Telescope could become the ârefractor bibleâ for amateur astronomers at all levels, especially those who are interested in imaging astronomical objects of every class. |
