PART II: TELESCOPES AND BINOCULARS

A: TOOLS OF THE TRADE (THE EQUIPMENT)

TYPES OF SCOPES - REFRACTORS

Though it's difficult to exceed the thrill of looking at a dark night sky with just the naked eye (and there are some things, like meteors and aurorae that are best viewed this way), even a modest optical aid can show thousands of times more stars and hundreds of objects invisible to the naked eye. This makes the sky an exciting place--full of wonderful things to find.

Binoculars are the easiest to use optical instruments, and offer the advantage of a completely correct image, which makes their use on land and sea practical while still being appropriate for stargazing and Moon viewing. While binoculars of 40mm and larger are appropriate for nighttime viewing, daytime viewing can be done with binoculars small enough to put in a shirt pocket. Scope City has a huge selection of binoculars for every use—all the way up to big giants that require heavy-duty mounts to support them.

Refractors are often the preferred telescope type for use in the daytime, and their advantages make them a superlative choice for nighttime viewing of the Moon, planets, or stars. This is the type of telescope you probably have a mental image of when someone says "telescope". It has a lens at the front, and an eyepiece in a focuser at the back.

It comes in a land/sea use configuration called a "spotting scope" (the image is correct, both up and down and left-to-right) or a longer, larger version on a heavier mount, usually referred to as an "astronomical refractor" (the image is correct up and down, but reversed left to right). The images produced have terrific sharpness and contrast, and are typically constructed very sturdily to take a lot of abuse. This is the type of telescope you can give to children, and keep all your life. Very big ones are very expensive, but the smaller, more portable, sizes are quite affordable. Appropriate sizes for land and sea use vary from 50 to 90mm, while astronomically-oriented refractors are usually from 60 to 150mm in diameter. The largest refractor in the world has a lens over 1000mm across (40"), but today, refractors larger than 150-200mm (6" to 8") are not considered practical due to their sizes and weights.
