 You Should Have a Pretty Accurate Idea:Binoculars In Low Light

Planning on using your Monocular Telescope in low light conditions, such as at dusk or at dawn? If so, when you buy your new binoculars you'll want to look for some specific qualifications to ensure that your vision won't be compromised. First, check the lens coating. If the binoculars are listed as fully multi-coated, this means that there are multiple layers of lens coatings on all lenses and optical pieces. This is important because the lens coating is what cuts down on glare and allows the most light possible to enter the binocular. The amount of light affects the brightness and clarity of the images you see, so during periods of low light you want to maximize the amount of light that is taken into the binoculars.

Additionally, the exit pupil is a very important indicator in how well the binoculars can function in low light. The size of the exit pupil can be determined by dividing the size of the objective lens by the magnification size, or basically the second number by the first in the specifications. For instance, a 10x50 specification would indicate an exit pupil of 5. The rule of thumb is to use an exit pupil that is the same size as the human eye. During periods of low light, the human eye's pupil expands to five to seven millimeters, to maximize the amount of light that can be collected. Thus, you'll want to choose a binocular with an exit pupil of five to seven millimeters as well.

You may see some binoculars with a twilight factor listed. This complex mathematical formula can be used along with the brightness index, or overall light transmission, to determine how well the binoculars will perform in low light periods. By also considering the lens coatings and exit pupil, you should have a pretty accurate idea of how well the binoculars will perform in low light.

 You Should Purchase A Giant Telescope Binoculars

Telescopic binoculars or astronomy binoculars proffer the highest and best of optic choices-a true telescopic presentation but without the unpleasant eye strain or squinting required of a telescope. Also the high-end giant binoculars offer image stabilization which is not possible in hand held binoculars but can be found in those that will be mounted. This way, a strong breeze, for instance, will not make your image jiggle to cause significant discomfort to the user. You should know that image stabilization requires the use of a battery to power it.

Telescope binoculars have two eyepieces, usually made with soft, molded cups for eye comfort.  Telescope binoculars may come with exchangeable eyepieces depending on the cost. Each eyepiece may come with its own focusing capability. Ordinarily they have a very sleek, modern design. When used with a tripod, they are the excellent telescopic binoculars for stargazing at its best.

Costs for such giant binoculars range from the very affordable Celestron SkyMaster Series, to thousands if you are desirous of the upper, upper best such as the VIXEN BT125A 125mm binocular telescope package with 2 LVW22MM eyepieces, tripod, fork mount 5835P2 which retails for $4,999.99 though, of course, these are not meant for the beginner astronomer. Costs for window-mounted tripods that can be used to mount your binoculars to a window sill or even your car window, begin under $50. Regular tripods start at approximately the same price, but can climb to as high as $500 for a some Swarovski models.

 Galileo is Often Thought of As Inventing the Telescope

Galileo is often thought of as inventing the telescope. He didn't invent the telescope but he was the first person to turn one toward the night sky. And the observations he made created the new science of modern astronomy where telescopes are used to help us understand our universe, our place in it, and how it works.Galileo first heard about the mysterious telescope in 1609 and set out to make a copy for himself. This first telescope magnified images about three times. And over the course of a decade Galileo continued to make more telescopes and his most powerful one magnified images about ten times. This telescope enabled him to see things never before seen. And it enabled him to change our view of the universe and of the objects in the sky.

The first thing that Galileo turned his telescope to was the moon and by observing it over the course of many nights he made an important discovery. He saw that dark areas on the surface grew and shrunk depending on where the moon was in relation to the sun. From this he made the correct deduction that these dark areas were shadows cast by craters and mountains. He further explained with geometry that the height of the mountains and depth of the craters could be correctly calculated. This was an astonishingly important revelation in our view of the universe because it was previously believed that the moon was a smooth surfaced object.

Another extraordinary observation, and the most important, that Galileo made was the discovery of the four largest moons around Jupiter. They were previously unviewable but with his ten-power telescope he could see them. And after viewing them over the course of several nights he observed that they moved. With further careful observation and calculation he proved that they revolved around Jupiter. And this was a universe changing observation because it was previously believed that everything in the universe revolved around the Earth.

Galileo went on to make many telescopes and to make many other important observations in both the night and day sky including the discovery of spots on the sun and the discovery of the rings of Saturn. His observations in the sky spurred on many other telescope makers and astronomers to further explore the amazing and mysterious objects in the sky. But more importantly he also spurred on other astronomers to apply the laws and lessons of mathematics and logic to their observations in a quest to understand how the universe works.

 A Timeline of Hubble Space Telescope History and Future

1924--Edwin Hubble looked up into the night sky to disprove the theory of a single galaxy. He proved that rather than just gasses and dust, the universe was filled with other galaxies. He was the first to prove that our universe was continuing to grow and expand. However, he did not have the benefit of the tools we have available today, so his knowledge was still somewhat limited although his vision was far-reaching.1924-1983--the concept of a Large Space Telescope (LST) was conceived, designed, revised and developed and implemented. In 1985, the LST was renamed the Hubble Space Telescope, to honor the man who started it all.

1990--After delays with its launch due to conflicts with the launch of the space shuttle, the Hubble Space Telescope was sent into orbit.1994--the telescope took pictures of a comet collision, and detailed photos of Pluto, as well as giving us a greater knowledge of Neptune and Uranus.1995--the Hubble took pictures of the "birth" of a star as it developed from interstellar clouds.1996--Photos from the Hubble Space Telescope show that quasars are actually nuclei which illuminate when a black hole uses energies from surrounding gases and stars.1997--The Hubble takes pictures which prove that black holes are bigger than the sun.1998--The most detailed pictures of the planets in our solar system are taken.

2004--The Hubble Space Telescope was able to document in pictures how, when, and why stars die and using the Hubble Ultra Deep Field technology, to take pictures of the expanding universe unlike any that had previously been taken. It also took pictures of Mars when it was closer to Earth than it had been in 60,000 years.2005--Took pictures of a comet with a projected piece of equipment from the Hubble Space Telescope.

Future Developments--The Hubble Space Telescope's mission is scheduled to end with this decade. Astronauts will go up, make repairs and assess the future usefulness of this tool in deep space discovery and a decision will be made about whether it should be discontinued or remain in service. But, no matter what decision is made, this telescope has been an amazing resource for a broader understanding of space and its limitless possibilities. Thank you, Mr. Hubble.

 Distinguished Brands:Top Orion SkyQuest Series Telescope

The Orion SkyQuest XT4.5 Classic is the perfect beginner telescope of the dobsonian kind. Although it is petite when placed next to the more professional reflectors in this product range, you will most likely be floored by the strength it demonstrates when placed next to your 60mm refractor. Indeed, it is 260 times more powerful! You can slew Mars, Saturn and track some great crater-filled sights of the moon. The XT4.5 is perfect for your children, and if you're excited about the outdoors, pack it along on camping trips.

A major step up from the 4.5", the XT6 sends you 80X more light than the XT4.5. The thing people will often tell you is that it's best not to spend less than $300 on a telescope. The 6" destroys this rule. Toss out the 60mm; the 6" mirror makes for an excellent 1st or 2nd telescope. The Skyquest 6" comes with an additional option, the Intelliscope. This add-on allows you to travel the sky by way of a computerized system.

Introducing the Orion XT8. This is powerful enough telescope to capture the ice caps on Mars and a catalogue of other attractions with flare. The 8" also has a price that is well positioned at just over $300. This telescope is also stocked with two laudable upsells, the Intelliscope (as outlined in the paragraph on the Orion XT6) and the GoTo box, which actually slews the telescope with use of a mechanical system. The GoTo system makes the 8" a wonderful starter scope for astrophotography.

The Orion XT10 is the most robust of the enameled steel tube dobsonians and is also the most impressive. Any larger and you couldn't stuff it in your trunk! The Orion XT10 is a luminous sky tracker that eats up the light rays and it will undoubtedly give you looks when you lay it out on camping trips. It is also very well priced within the $500 mark. A lot of astronomers with this kind of budget will forgo picking up a larger telescope for the GoTo improvement that marks this as a fantastic scope for astrophotography.

The 12" mirror marks the end of the enameled tube-based telescopes and announces the bar-based truss. The reason for this will be undeniable when you think of lifting this larger telescope. Having it as a solid tube would create problems when moving it in and out of rooms. The bar-truss system reduces this problem. The Orion XX12 has incredible optics and is truly a night gazer that can view star nurseries and gas clouds with ease. The telescope is installed with either the Intelliscope or the GoTo encoder.

 Types of Telescopes & Advantages: Newtonians and Catadoptric

Newtonians are a type of telescope, which is also known as catoptrics. This type is different from the other telescopes because it has the lowest per inch of aperture compared to refractors and Catadioptrics, because lenses are more expensive to produce than mirrors, especially in medium to large apertures. Newtonians deliver very bright images and are low in optical aberrations.

Catadoptric telescopes are the most popular type of instrument, with the most modern design, marketed throughout the world in 3 1/2 and larger apertures. Its very good for looking at different planetary, lunar, and binary stars. If you like to take photos with your telescope this type of instrument is excellent for deep sky observing or astrophotography with fast films or CCD's.

 Interesting Facts About Hubble Space Telescope:Servicing Missions

In Feb. 1997 the Hubble Telescope received its Second Servicing Mission. The space shuttle Discovery was boarded by seven astronauts. They installed two technologically advanced instruments, onto the Hubble. To observe space objects in infrared wavelengths the Near Infrared Camera and Multi-Object Spectrometer was installed. The second instrument installed was the Space Telescope Imaging Spectrograph, which is used to take detailed pictures of celestial objects and hunt for black holes.

Service Mission 3A in December 1999 was a busy one for the space telescope. Their goal was the replacement of gyroscopes, which accurately point the Hubble at celestial targets. The crew replaced all six gyroscopes as well as one of Hubble's three fine guidance sensors, which allow fine pointing and keep Hubble stable during space observations.

Service Mission B for the Hubble Telescope occurred on March 1st 2002 when NASA launched the space shuttle Columbia, where its seven member crew met with Hubble to perform a series of upgrades. The astronauts performed five spacewalks. Their mission was to install the Advanced Camera for Surveys. The ACS doubled Hubble's field of view and collects data ten times faster than before.
