German Made Binoculars - A Buyer's Guide

!9#: German Made Binoculars - A Buyer's Guide

German made binoculars are some of the best binoculars made on the market. Although, there are other makers in other countries, Germany has consistently produced reliable and efficient binoculars through the years. Aside from this praise, what would a normal person just starting out need to know when purchasing a pair of binoculars.

So, when it comes to buying binoculars, what do you need to know? To sum it up:
The binoculars need to have a large objective diameter. Having a large objective diameter increases the field of sight. Putting it in other terms, the larger the diameter, the more light can get into your eye. With more light you will be able to see fainter objects. With binoculars with small objective diameters, you will not be able to get a lot of light into your eye, thus fainter objects will not be visible. Get a pair of binoculars that has a magnification no greater than 7-8. Also find a pair with a proper size exit pupil Good eye relief is also important fully multi-coated optics BAK-4 Porro prisms rugged design - Binoculars tend to be taken everywhere and tend to fall an extraordinary amount of time.

These are just a foreground matter of facts when starting to look at binoculars. Now, depending on what you will be using the binoculars for will also bring about a few more questions. For example, are you going to use your binoculars in the dark? If so, you may want to consider investing in a pair of night vision binoculars. But, how about if your just looking at the stars. Then a pair of night vision binoculars would not be needed. In this case I would opt for a pair of high power binoculars to bring the stars image closer for better study.

Investing in a good pair of German made binoculars takes a little bit of research, but it is well worth it. Start from these basics and build from here and you should end up with a pair of binoculars that will last you for a long time.

New Telescopes for Beginners

!9#: New Telescopes for Beginners

There are two basic types of telescopes: one in the reflector and the other is the refracting telescope. It is important to know the difference so the you can choose what is correct for your circumstances.

The first telescopes were the refractor type. A man named Lippershey was tinkering with eyeglass lenses and noticed that when he place one lens in front of the another the object resting just beyond the lenses were magnified slightly.

He soon built the first spyglass, the first optical telescope which focused light into the human eye. It also used two lenses. The first lens (the objective lens) collects and refracts (bends) incoming light, focusing it into a tiny image.

The secondary lens, placed directly in front of the first, magnifies the image, making it look larger to the eye.

This new invention was used as a novelty at parties and later by army officers to observe enemy troop movement up close. No one thought about using it to study the skies.

Galileo is best known for taking this invention, improving on it with more magnification, and turning it upwards to observe astronomy. He was the first to see other planets.

Telescopes were not only getting larger and more powerful the quality of the lenses were improving rapidly making images sharper.

A Scottish mathematician named James Gregory in the 1660s tried building a telescope that used mirror instead of a lens to gather light.

Isaac Newton picked up on the idea, came up with a simpler and better reflecting telescope, or a reflector. Light enters the telescope's tube from an opening in the front. The light travels to a mirror located in the back and bounces off.

Because the mirror curves inward slightly the reflected light comes together and forms a small image in the center of the scope.

To get the best viewing for your money your best choice would probably be a good pair of binoculars (two telescopes for the price of one). After that reflector telescopes are great for beginners. When you have more experience move up to a refractor telescope.

Happy viewing, mary

Solar system lesson plans help people learn about the planets and their features in a systematic way. The goals of a well drawn-out solar system lesson plan include the development of thinking, reasoning and collaborative skills.

Topics included in a common solar system lesson are the basics of the solar system, relative distances of planets within the solar system, exploring the planets, and solar system adventures. The total time required is 3 classes with approximately 60 minutes each. The total preparation time for the teacher is about 1 hour. The first period introduces the solar system which is followed by a group discussion. The second period covers relative distances of planets in the solar system and the observation of solar images. Chart preparation of planets is part of the homework. The third period includes discussion and review of planet features from homework, the summarizing of the concepts and facts for gas giant planets.

The objective of a middle school level solar system lesson plan is to give a thorough knowledge of space and the vast emptiness between the planets. These lessons also cover ways of determining the size of a star. Topics for middle school level lesson plans include exploring the planets, charting the planets, solar system and the universe generally. The total time required for this is 4 classes with approximately 60 minutes each. The normal preparation time for the teacher is 2 hours.

High school level lesson plans' objective is to make students observe and explain the apparent movement of the sun and the moon, relating the location of the sun to the time of day and naming and describing the seasons. Before going to the lessons, the student should understand the concepts of basic physics and math including the concepts of ratio, angular velocity, and measurement of an arc in a circle. The topics covered for high school level students are planetary rotation, angular velocity, period of rotation, orbital motion, and angles and angular measurement. The time required for completing the full unit is several days to two weeks.

Venus and Mercury at Sunset

!9# Venus and Mercury at Sunset

Venus is very bright, you can spot it easily either after sunset or before sunrise. Mercury is a difficult planet to observe, due to its proximity to the Sun. Few people have actually seen Mercury. It is even said that Copernicus' greatest regret was never seeing Mercury in the sky during his lifetime. View is very similar to the one in my 15x70 Celestron SkyMaster binoculars. Filmed in Campeni, Romania with a JVC Everio camcorder (35x optical).
