Why Astronomical Binoculars Are Becoming Popular Over Telescopes

Astronomy is taught in universities, colleges, and selected high schools today. While observing the stars is considered a scholarly challenge, amateur gazers find it enjoyable entertainment. The opportunity to view the stars in an appreciable way requires a telescope. The need for using sophisticated equipment for viewing the stars has limited the number of participants. More recently binoculars have been used for astronomical viewing. The result is appreciable for many people considering the easier mobility and simpler operation of the binocular equipment. There is a great difference in price, comparing a telescope and binoculars. Transporting a telescope has always been a difficult assignment because the instrument is cumbersome and setup is an involved process. The best binoculars for astronomy use are (7 x 50) or larger. Any size binocular can be used for viewing stars and sky objects, but choosing quality equipment promises better results.

The binocular rating has two basic parameters: magnification and aperture. The first number tells the magnification factor. A second number is the aperture, the diameter of the lenses. A (7 x 50) binocular shows a view magnified 7 times and it has objective lenses 50 mm wide. Objects will appear brighter with wider lenses. The area of land or sky that is presented to your eyes by using binoculars is referred to as the field of view. Astronomers have expressed these fields in degrees. In order to define the quality performance of their products, binocular makers present the field of view in mathematical conversions that show a variance of fields. Binoculars with larger fields of view may work better, but the cost is considerably more.

When choosing binoculars for astronomical use, both technical quality and optical quality are important aspects. Many astronomers are professionals, but amateur observers have embraced the romance of stargazing also. Each group enjoys the beauty of the sky and they appreciate the gentle relaxation gained by watching the stars. Adaptation of binoculars for a telescope offered change along with creating new opportunities. One group of star gazers aims to enjoy their astronomical pursuits while using as little amount of equipment as possible while the another group requires a sophisticated telescope for their endeavors. Each group will choose equipment for viewing/observing the stars after consideration of all available information. Nevertheless, the capabilities of binoculars appeal to both groups as they choose equipment that best fits their needs.

Death Stars, Weird Galaxies, and a Quasar-Spangled Universe: The Discoveries of the Very Large Array Telescope

Death Stars, Weird Galaxies, and a Quasar-Spangled Universe: The Discoveries of the Very Large Array Telescope
In 1931, Karl Jansky was hired by AT&T to search for sources of static that might interfere with radio waves for transatlantic communications. Jansky identified static from thunderstorms and random radio noise from devices on Earth, but he also found a radio hiss from the Milky Way galaxy.

After World War II, astronomers constructed more radio telescopes with greater sensitivity to faint radio signals from space. In the 1970s, the National Radio Astronomy Observatory built the Very Large Array (VLA) radio telescope, on the plains of San Agustin, New Mexico. The VLA is well equipped to hunt for strange objects and solve astronomical mysteries.

The VLA receives radio signals from outer space. Most are so faint, a blastingly strong signal would be a cell phone ringing on the moon, 238,900 miles away from Earth. The VLA has shown ice on the burning-hot planet of Mercury, has discovered a burst of brand-new star formations, and has probed dying and exploding stars.

Karen Taschek introduces young readers to the wonders revealed by the VLA. She begins with basic information on our solar system and our own Milky Way galaxy and then extends the discussion to galaxies billions of light-years from Earth.

Nikon Coolpix 5700 5MP Digital Camera w/ 8x Optical Zoom

Nikon Coolpix 5700 5MP Digital Camera w/ 8x Optical Zoom
Nikon's Coolpix 5700 digital camera combines Nikon's world-renowned Nikkor optics, an 8x optical zoom, and a 5-megapixel CCD sensor for superior image quality. With its maximum resolution of 2,560 x 1,920 pixels and file sizes of up to 15 MB, you can create brilliant color prints sized 16 by 20 inches and beyond. The Coolpix 5700 provides great control over picture composition, and plenty of latitude to crop and resize images without digital artifacts becoming noticeable in the final print.

The 8X optical zoom Nikkor lens offers a 35-280mm zoom range (35mm equivalent), and uses Nikon-developed ED (extra-low dispersion) glass. For even greater magnification, the stepless 4x digital zoom provides for a maximum zoom range of 32x, so you can capture details even from great distances.

The Coolpix 5700 features Nikon's exclusive clear-image mode for lower-resolution shooting, plus noise-reduction mode for use with longer exposures. It also offers a three frame-per-second burst mode and a top shutter speed of 1/4,000 second, great for action-packed outdoor and sports photography.

You can frame subjects using the various-angle LCD monitor, or the new electronic viewfinder for through-the-lens viewing of scenes and menus. Nikons "quick review" makes viewing images on the included memory card a snap, and a five-area multi autofocus lets you pick your focus spot.

Its movie mode enables you to record full-motion video for up to one full minute with sound. A built-in speaker provides instant confirmation and playback capabilities for digital movies.

The Coolpix 5700 comes equipped with an automatic pop-up flash, plus a hot shoe for additional flash units. The bundled NikonView 5 browser software (for Mac and Windows) makes it simple to organize, retrieve, and print images. It includes a lens cap, camera strap, 16 MB CompactFlash card, AV cable, USB cable, rechargeable lithium-ion battery (EN-EL1), and battery charger. It is compatible with type I and II CompactFlash memory cards, as well as IBM Microdrives (512 MB and 1 GB).
