Meteors (Sky & Telescope Observer's Guides)



Meteors (Sky & Telescope Observer's Guides)
Sky Publishing MeteorsGlimpsing occasional "shooting stars" is exhilarating. This book helps you learn how to start your own meteor-hunting program. In great detail, Neil Bone teaches you the origins and science of meteors, naked-eye-metor watching, and record keeping. A seasonal calendar of annual meteor showers and their characteristics is also included.



Sky Atlas for Small Telescopes and Binoculars



Sky Atlas for Small Telescopes and Binoculars
This is the Atlas for sky observing begginers. The constellations are easy to locate, and all the objects in the atlas are within reach of binoculars or a small (2 inches or less) telescopes. The forward gives a basic overview of celestial motion. The selection of objects insures success for the beginner with the easiest to find objects in the sky. Many beginners do not know which objects are within reach of their equipment and end up frustrated and unsuccessful. This atlas describes if the object is viewable in binoculars, or a small telescope, or with the unaided eye. Descriptions of objects on a page are given on the opposing page. A



Celestron FirstScope 90EQ Telescope



Celestron FirstScope 90EQ Telescope
Celestron's Firstscope 90EQ refractor telescope is a good choice for anyone who wants to try out astronomy at an affordable price, and it can double as a high-power spotting scope. Standing five feet high and weighing nearly 30 pounds, the Firstscope 90EQ is a serious sized achromatic refractor. Achromatic refractors occupy a middle ground between 60mm beginner scopes and premium-priced Apochromatic refractors.

Refractors are known for their sharp, high-contrast views of the moon and planets, and the Firstscope 90 includes everything you need to get sharp views of the moon right out of the box. The low-power 20mm eyepiece (50x) shows a nice overall view of the moon, while the 10mm eyepiece (100x) can be used to zoom in for more detail. When the quarter moon is in the sky, I like to look for detail along the "terminator," the dramatic boundary between bright sunlight and dark shadow.

Brighter deep-space objects also show up nicely in the Firstscope 90. On a moonless night, I like the way the 20mm eyepiece frames the ghostly glow of the Orion nebula. Zooming in with the 10mm eyepiece, I can easily pick out all four stars of the Orion nebula's embedded multiple star, the Trapezium. The moons of Jupiter and the rings of Saturn are easy to see with the 10mm eyepiece (100x). With careful focusing, I was even able to detect the Cassini division in Saturn's rings using my own Ultima 7.5mm eyepiece. Low-cost refractors like the Firstscope 90 can be troubled by false color and spherical aberration, but I find these effects are well controlled at moderate powers. When I look at Jupiter and Saturn at magnifications over 100x however, the images are not as sharp as the ones I see with my C102HD refractor.

The equatorial mount included with the Firstscope 90EQ is designed to track stars and planets. When I set up the telescope, I simply point the polar axis at Polaris, the North Star. This allows me to keep celestial objects in view by turning one slow-motion knob, and an optional motor drive is available for hands-free tracking. Celestron also offers the Firstscope 90AZ, which is the same telescope with an alt-azimuth mount. The standard equipment Kellner eyepieces are just average quality; I'd add a 32mm plossl like the one in Celestron's optional accessory kit to bring out the full view of deep space highlights like the Pleiades. You'll also want some star charts to help find planets and star clusters; I like the monthly star charts and viewing tips in Night Sky magazine. --Jeff Phillips

Pros:

  • High-contrast views of the moon and planets
  • Durable, low-maintenance design
  • Can double as a spotting scope
Cons:
  • Eyepiece quality just average
  • Equatorial mount can be awkward to use
  • Planet views over 100x are a little soft
  • 90mm is a bit small for deep space viewing



Tools of Radio Astronomy (Astronomy and Astrophysics Library)



Tools of Radio Astronomy (Astronomy and Astrophysics Library)

This substantially rewritten and expanded fourth edition outlines the most up-to-date methods and tools of radio astronomy. Tools of Radio Astronomy gives a unified treatment of the entire field of radio astronomy, from centimeter to sub-millimeter wavelengths and using single telescopes as well as interferometers. The basic physical principles are described and a complete outline of the instrumentation, observational techniques, and methods of measurement and analysis are given. The goal of this standard reference and text is to prepare readers to carry out observations and relate the data to physical processes in interstellar space. In this fourth edition, the chapter on interferometry and aperture synthesis has been thoroughly revised in the light of most recent developments, as has been the chapter on molecules in interstellar space, and material on receiver technology.
