Telescopes & Its Numbers

Telescope Eyepiece Number
The telescope eyepiece number denotes the focal length of the eyepiece. It is not the magnification of the eyepiece.

Magnification of the Telescope
For any telescope, you can calculate the magnification of the eyepiece by dividing the focal length of the telescope by the focal length of the eyepiece. For example – by using a 20mm eyepiece on a telescope of focal length of 1000mm its magnification power will be 50x (1000/20=50), however, a 10mm eyepiece on the same telescope have magnification of 100x (1000/10=100). The eyepieces are exchangeable, so you can use a telescope to obtain a range of powers.

Magnification (buy telescope)
You need only adequate magnification to acquire a usable image. If you happen to obtain blurry images without much detail, you need to decrease the magnification. All this also depends on atmospheric conditions - clarity and constancy, the object you are observing, and the size of the telescope. A larger telescope can allow you to use more magnification by the time the images start becoming blurry.

Beginners
Begin viewing with an eyepiece for lowest magnification until you get a hold of the equipment. Therefore, you need to buy an eyepiece 'bigger number' denoting longer focal length. Remember the number on the eyepiece is the focal length, not its magnification.

Increasing Magnification
The basic law of optics affirms that increasing the magnification decreases the brightness of the image. Too much increase of magnification can cause an object to become faint to notice.

Fading Objects in the Field of View
It is important to understand how to choose a telescope, as a telescope along with magnifying the object in the sky also magnifies the earth's rotation. The added magnification in a telescope causes the object drift out of the field of view. A manual telescope mount can constantly 'recapture' the object by minor movements in the telescope. To keep the object in the eyepiece you can use motorized mounts to move the telescope with the rotation of the earth.

The Basic Anatomy of Picture Framing

Picture framing is an art that requires good creativity. Like every art work it does a few rule of thumb, added to that a bit of creativity and inquisitiveness you can go on to build your confidence in framing your art, your certificates, or memorabilia, and whatever else you want to frame and display.

Fundamentally, all types of framing are based on four important decisions that you will have to make such as – the frame, the color matting, the mounting or backing material, and the glass. Each of these components has only one of its kind personalities that are helpful in understanding when buying a frame.

The Frame: The frames used for picture framing are made of either metal or wood. If you prefer a warmer and inviting look, you should go for a wooden frame. Wooden frames have a conventional look, are attractive, and enhance some specific types of artwork like paintings, bright color photograph, or an heirloom piece. The metal frames having straight edges and sharp corners, have propensity to stand for bold contemporary and industrial look. Black and white photography and other modern media look extraordinary in metal frames.

The Mat Boards: The selection of matting requires you to consider three decisions – the grade, the number of layers, and the choice of color. The grade of mat is based on its acidity level, the lesser is better. Number of layer refers to the number of mats and color, which can be any color that enhances the picture to be displayed.

Mounting Board: Mounting board is the third important thing in picture framing. It is sometimes called the foam board and forms the back of the frame to which artwork is attached.

Glass or Glazing: The last step in framing is the type of glass, or glazing to your frame that is the cover that protects your art. These are available in different qualities such as acrylic, anti-glare glazing, ultra violet protective, and a combination of both anti-glare and ultra violet reducing glazing.

Selecting Hunting Binoculars

If you are a hunter that has been in a deer stand, climbed the Rockies or searched for elk, then you know that the right binoculars can make these adventures even more successful and enjoyable.  They can expose you to different animals and environments that you might not have otherwise seen on your own.

A great pair of binoculars can last you a lifetime and give you many years of wonderful memories.  So when searching for a pair of binoculars for hunting, understand that you want something that performs well with low light.  As a hunter, it is expected that most viewing is done either when the sun is rising or setting.  This is why a majority of hunters want to use full sized binoculars that have objective lenses with 40 to 50 millimetres.

In terms of magnification, this will rely on the different types of terrain and game that you hunt.  A wide FOV that is provided with binoculars with 8x or 7x magnification is wonderful for skimming tree lines and fields for wildlife.  A wide angle binocular gives the ability to see wildlife that is lurking along the perimeter.

When hunting in open areas that have little greenery, you will need to have binoculars that can get wonderful distant views.  Magnification of 10x is great for such areas.  A lot of western hunters like to use  10 x 56.  But remember, that you won’t get steady images with anything over 10x unless a tripod is used.  The quality will not be as good unless it is used.

It is also important that your binoculars are rugged and durable, especially if you will be out in the wild with harsh weather conditions.  Roof prism binoculars will perform better in locations with a lot of moisture and higher degrees.  They do better than porro prism style binoculars, which tend to be standard.  A majority of the roof prism binoculars that are sold in this day and time are waterproofed and will not fog internally.  Binoculars that do not fog up internally have an inert gas like nitrogen or argon.
