Everyday need to be fun. And to add to additional fun - a telescope will most likely do the trick.
Going out everyday to unique places or even star gazing at night with a telescope would be extra fun than usual.
This way you could point and take a extra closer look to the 1, for example, constellation that you like most.
Telescopes are fun. Get a telescope and let everyday lif......
The principle in which the telescope works is very simple. There are two lenses that make up the task of viewing the objects that are at a distance. One of the lenses picks up the light from the object viewed and makes it available at a focus point. Another lens picks up the bright light from the focus point and spreads it out to your retina so that you can view. The lens that picks up the ligh......
Refractor- It is most commonly used and traditionally designed telescope. The telescope has a lens or mirror in the front to gather light and capture an image. It is a little expensive but the cost depends on the aperture, so a small refractor can be good option as a telescopes for beginners.
Newtonian reflector- It can be viewed using an eyepiece.Larger apertures are available but at t......
The refracting telescope is the telescope most often associated with astronomy. It was the first type of telescope made and uses a set of lenses to collect and magnify the light of whatever you are looking at. Because of the cost and weight of large lenses refracting telescopes don't have the aperture that reflecting telescopes do, however they tend to have a much longer focal length. This larg......

First thing you see when looking at the focuser, you will find that most department store telescopes come with cheap plastic focusers. This may not seem important at first, but over time those cheap plastic parts will began to wear out, slip, and eventually stop working. Once it cracks or starts to slip, you may find replacing the focuser would be more expensive than the telescope is worth.

Dobsonian telescopes were developed in the 1960's by John Dobson, an amateur astronomer. Having been fascinated by the Universe, John Dobson built his telescope, based on the Newtonian reflector telescope, out of every day common materials such as plywood and cardboard and is mostly, if not always alt-azimuth mounted. This simply meant that it had a simple two-axis mount for supporting and rota......
Refractor telescopes, also known as refracting telescopes or dioptric telescopes bend light to make parallel rays converge at a focal point. The refractor telescope design was predominantly used in spy glasses before its use in astronomical telescopes. The refractor telescope was the first kind of telescope invented. It utilises' a glass lens as a medium to refract the rays of light to form an ......
Basically, binoculars with an objective lens smaller than 30 mm are considered "Compacts", while ones with lenses larger than this are described as "Full Size". In most cases, I recommend people to go with a full size binocular for watching birds and nature. One reason is that they are just a lot easier to look through. A reason for this is compact binoculars have correspond......
binoculars come in either the Roof Prism or Porro Prism design. Generally, the Roof prism is more desirable, but can be more expensive for the same quality glass and optics compared to a Porro Prism. But, the more streamlined design and more rugged hinge design makes it worth it in most cases. Water Proof and Fog Proof are also desirable features if you're going to possibly be using the binocul......

1. If your binoculars came with a micro-fiber lens cleaning cloth, use this to clean your lens after blowing or brushing away any dust or debris. Gently and with light pressure, wipe the lens in a circular motion. On the larger objective lens you may want to 'ball up' the cleaning cloth and twist lightly in a circular motion on the lens. By doing this you will exert less pressure on the lens th......
When you are in the market searching for that best model for less than 100 dollars things can become tough as you will constantly find things that are much better at say 120 or 150.

The formula that shaped known telescopes over the centuries of development is pretty basic, well known, and proven- bigger is better. This is the same as saying that larger aperture provides brighter image, while longer focal length provides greater magnification. Even so, is this formula written in stone? Let's put the formula to the test. Can large magnification be obtained without long focal......
All optical instruments are design around focus; therefore it will always be a top priority in the formation of clear image. Magnification and brightness are of secondary importance, they are the result after focus is achieved. It is the critical distance of focus that determine the maximum magnification and brightness at which an image will be clearly viewed.
Magnification describes t......
Refractor telescopes cannot obtain a 7 millimeters exit pupil without being affected by aberrations. In order to overcome this, telescope designers attempt to allocate a balance between magnification and brightness. Resolving power describes this balance. The compromise will reduce brightness, but increase magnification power and image clarity by the same proportion. The ocular plays an importa......
Technique in lens and mirror manufacturing has improved significantly over the centuries. With the aid of computers, lasers, and robotics technologies, optics can be made with precision accuracy.
