Seen | Unseen: Art, Science, and Intuition from Leonardo to the Hubble Telescope

Seen | Unseen: Art, Science, and Intuition from Leonardo to the Hubble Telescope
iSeen | Unseen/i is a deep, richly illustrated, and erudite analysis of the interconnections between science and the visual arts. Martin Kemp explores the responses of artists, scientists, and their instruments, to the world - ranging from early representations of perspective, to pinhole cameras, particle accelerators and the Hubble telescope. From Leonardo, Durer, and the inventors of photography to contemporary sculptors, and from Galileo and Darwin to Stephen J. Gould, Kemp considers the way in which scientists and artists have perceived the world and responded to its patterns, and sees common 'structural intuitions' reflected in their work.

The Best Telescopes Out There

This will be a big surprise. Can you tell me what the best telescope out there today is? There are actually two of them. If you said your eyes, you are correct.
You were born gifted with two telescopes that can focus from one inch to infinity and beyond. They have a field of view of about 110 degrees, and they have built in lens covers. They open and close at about Barometer 1/40 of a second. Eyes can detect subtle color changes as well as any variance in color. They also send three dimensional depth information to your brain. No telescope could ever do all these things.
Go out before you start with the telescope and look at where you will be pointing it. Pick out several constellations by sight and look for the moon and a planet. Make a mental picture so you know where t go to come back to the object when you want to. Just relax and go out in the warm Star Gazing night air and look up. It really is that simple.
To get the most from learning astronomy, you must have a lot of patience. You Meade Lx200 may go several nights without seeing anything new. This is what frustrates Tele Scope beginners. Start with the moon and look at its brightness. Look for craters and mountains. There is so much to the moon that you could find something new every night for the next year.
Don't give up though. Even though you didn't find what you were looking for doesn't mean it's not out Mead Telescopes there. It just means you haven't been able t see it Eyepiece Newtonian yet. Keep looking each Monoculars Tasco night. You may find something else you weren't looking for and that will lead to other new objects as well. Look around star clusters and the planets. You may even spot some comets or meteors.

Celestron NexStar 80 SLT Computerized Telescope

Celestron NexStar 80 SLT Computerized Telescope
Celestron's computerized NexStar 80 SLT offers a significant step up in performance compared to 60mm telescopes. This 80mm telescope has 78% more light gathering power than a 60mm scope, and that means more Lunar and planetary detail, and more stars visible on any given night.

Celestron's new SkyAlign technology is remarkably quick and easy to use. You won't need a GPS receiver or a star chart. In fact, if you can see the moon just choose "Solar System Align", enter the date and time, point the scope at the moon and push the "Align" key. This simple procedure was all I needed to initialize the computerized tracking system and start taking pictures with my Celestron NexImage CCD imager.

The NexStar computer allows the telescope to track quietly and accurately with surprisingly good precision. When I use the three star "SkyAlign" mode to initialize the telescope, the GoTo system consistently places deep space highlights like the Orion Nebula, the Andromeda Galaxy and the Double Cluster in Perseus near the center of the low power eyepiece. The standard equipment 25mm eyepiece (36x magnification) or an optional 32mm plossl (28x) provide nice low power views of these objects. The tracking system also makes it easy to get some delightful high power views of the moon and planets. The included high power 9mm eyepiece gives a magnification of 100x, but I find the views are quite good up to 150x when I use an optional 6mm plossl.

The NexStar 80 SLT is large enough to show good detail on the moon and planets, but it's not large enough to bring out much detail in deep space objects. Globular cluster M13, for instance, looks very comet-like with a glowing core and feathery edges; it simply takes a larger telescope to see M13's individual stars. The other drawbacks to this telescope are its short battery life and a mount that wobbles while focusing at high power. Try setting an external 12 Volt battery like Celestron's Power Tank on the accessory tray; it will power the scope and reduce vibrations at the same time. -Jeff Phillips

Pros:

Easy computerized pointing and tracking

High contrast views of the moon and planets Cons:

Short battery life

Wobbles while focusing at high power

Too small for deep space

Today's bushnell telescope ArticleBuying a Telescope?

What an experience you have ahead of you if you are choosing a telescope to look at the night sky!

But even if you want a telescope for other purposes, it is important to gather a few facts about telescopes first so you know what to look for when you buy.

Types of telescope

Essentially there are two types of telescope:

1. A refractor telescope ? that?s the ?traditional? type of telescope which has a lens at the front, a tube for the body, and an eyepiece at the other end.
2. A reflector telescope ? which has an open end and a mirror at the other which directs the image to another mirror and then directs that to the eyepiece

Which should you go for?

Well, if price is important, then generally speaking you will get better ?value for money? with a reflector telescope. But purists will claim that you will get a better quality image with a refractor. So, if you can, try each out and make your decision.

Buying tips

DON?T be sold on magnification! Ads and salesmen will talk about so many hundred times magnification. That?s not the most important factor at all ? too much magnification often only succeeds in giving you a more blurred image!

What counts is the amount of light collected by the telescope ? and that depends on the size of the lens or the mirror (as a rule of thumb, multiply the diameter of the objective by 2.5, and you?ll get an idea of the magnification possible).

And don?t skimp on the tripod and mountings; make sure they are solid and steady. When you are looking at a distant object at high magnification, a wobbly tripod is not something that you want!

If you can afford it:

Go for a GoTo telescope. What?s that? Well you align it with several known objects in the sky, and then you can find just about anything else with a supplied remote control ? saves hours of time and frustration.

Or go one step further and invest in a GPS telescope ? using the same principle of satellite navigation used in cars, this will find any known object in the night sky for you!

Final word of warning

DON?T under any circumstances, point your telescope at the sun ? ever. The damage you can inflict on your sight is unbelievable. Do not be tempted ? just don?t do it!

Happy viewing.

HOW TO BUILD AN ASTRONOMICAL TELESCOPE

HOW TO BUILD AN ASTRONOMICAL TELESCOPE
By Rob Smith

ISBN: 978 1846930430
Published: 2007
Pages: 120

Description

This book is based on a GCSE course, and is very popular

The view through the eyepiece of a good Telescope is an experience which often marks the turning point from an interest in telescopes to an overwhelming urge to own one. However, a visit to a telescope supplier and a study of the prices, can deter all but the most passionate of Amateur Astronomers. However, the remedy is a simple one; almost anyone who wishes to may build a Telescope capable of studying the surface of the Moon, the rings of Saturn, the brighter Moons of Jupiter, Nebulae and Double Stars.

About the Author
