Review
From the reviews: "This book covers a huge subject: catadioptric telescopes. … It’s an invaluable resource describing what equipment is available, including Schmidt-and Maksutov-Cassegrains and their Newtonian variants. … Mollise includes details of brands such as Sky-Watcher and Orion Optics, increasing the book’s value to a wider audience. … overall this is an enjoyable and very informative book … ." (Steve Richards, Sky at Night Magazine, September, 2009) “If you frequent online discussion areas for astronomical assistance or amusement, you’ve no doubt seen a message or 20 from ‘Uncle Rod’ Mollise. … His latest book tackles one of his favorite subjects: the compact … powerful catadioptric telescope (a ‘CAT’), which comes in Schmidt-Cassegrain, Maksutov, and Ritchey-Chrétien configurations. … Mollise walks you through everything you need to know about these scopes … you can make an informed decision to buy one and operate it effectively.” (Sky & Telescope, April, 2009)
Product Description
Choosing and Using the New CAT will supersede the author’s successful Choosing and Using a Schmidt-Cassegrain Telescope, which has enjoyed enthusiastic support from the amateur astronomy community for the past seven years. Since the first book was published, a lot has changed in the technology of amateur astronomy. The sophistication and variety of the telescopes available to amateurs has increased dramatically. Computerized SCTs, Maksutov-Cassegrains, and most recently Meade’s new and acclaimed Ritchey-Chrétiens have come to dominate the market. That means that all amateurs considering the purchase of a new telescope (not only a SCT, and not just beginners) will benefit from this detailed guide. Choosing the right telescope for particular kinds of observation (or even for general work) is far from easy – but Rod Mollise gives invaluable advice and guidance.
From the Back Cover
Catadioptric telescopes (CATs), such as the Schmidt Cassegrains, are increasingly popular with today’s amateur astronomers and are capable of showing even the novice observer thousands of beautiful deep space wonders. Modern CATs, though, have become increasingly reliant on computers. This allows them to automatically point to and track celestial objects, making astronomy more accessible to more people than ever before. Unfortunately, because of the high-tech nature of these telescopes, selecting one and learning how to use it is often a difficult experience for stargazers both old and new. That’s where Choosing and Using the New CAT comes in. This book guides even the most greenhorn astronomer past the pitfalls encountered on the path to enjoying the beauties and mysteries of the universe. Here you will learn not just which telescope is right for you but how to set up, operate, and maintain the most complex and electronics-laden CAT. There are plenty of tips for keeping the new CAT happy and working correctly, and there is even guidance on advanced applications, such as hooking computers to CATs and using these telescopes to take gorgeous pictures of planets and deep space objects. This book gives readers the benefit of the author’s thirty-five years experience using and enjoying catadioptric telescopes and solving the problems that inevitably crop up. If you dream of owning a telescope or are frustrated by the telescope you already own, this is the book for you!

  Product Description
Astro-imaging is an immensely rewarding hobby, but the challenges involved can seem difficult to beginners. Some of the best objects to start on are the planets of our own solar system and the Moon. Big, bright targets like Jupiter, Saturn, Mars and the Moon make wonderful models as they strut their way around the Sun on their celestial catwalk. The planets are relatively easy to locate and identify in the night sky, so solar system objects prime imaging targets for all astro-imagers. The Orion StarShoot Solar System Color Imager IV is equipped with features that make it easy to take your own images of objects in our solar system. Its 1/3-inch format CMOS imaging sensor with a 1280 x 1024 pixel layout can take sharply detailed planetary and lunar images. Each pixel is a mere 3.6µm x 3.6µm in size for exceptional image resolution in 24-bit RGB color. Since the 8-bit output StarShoot Solar System Color Imager IV is progressive scan, all pixels will be used for each and every exposure. At full 1280 x 1024 resolution, you can capture up to 15 frames per second. By stacking multiple exposures to create a single picture, you can increase image detail significantly.

Tech Talk
Objective Lens: The diameter of the objective or front lens. The larger the objective lens, the more light that enters the binocular, and the brighter the image.

Field of View (F.O.V.): The side-to-side measurement of the circular viewing field or subject area. It is defined by the width in feet or meters of the area visible at 1000 yards or meters. A wide angle binocular features a wide field of view and is better for following action. Generally, the higher the magnification, the narrower the field of view.

Roof Prism System: In roof prism binoculars the prisms overlap closely, allowing the objective lenses to line up directly with the eyepiece. The result is a slim, stream-lined shape in which the lenses and prisms are in a straight line.Amazon.com Product Description
