Options for the solar telescope.

Binoculars, small telescopes connected and installed side by side with mechanics remote viewing. This is useful, durable, lightweight and easy to use. Astronomy telescope will allow you to see up to 40%, with a more one-note compared to the telescope eye.

Zoom.

Selection also reflects the increase in intention to use. Mobile on how to set to zero. Do not drop your equipment bag. This means that there must be a magnification of 12x to the bottom of the glass stability. But the combination of size, but makes the lens of a hundred stars and galaxies 7x to 12x binoculars.

Therefore, you can also define an exit pupil binocular. (In virtual-optics), with the eyes. This is done by dividing the size of the lens with the magnification power.

Human eye 2 mm output of summer students, a harangue. Students should leave more than 5 mm, more light to be useful. As all the edges of glass, to consider the value of distance can be achieved if the focus or the so-called eye relief. 9 millimeters binoculars eye relief to be unpleasant show.
Travel can help effectively 15-20x zoom. Astronomical Telescope 15x to 30x and can lead to more information about astronomy. This is the moment of 25x100mm very effective in light and dark at night.

A giant telescope with only a small number continue pretending. This version is even if you have some resoluble eyes.

Size.

Lens size - Aperture (opening or hole through which light is known) is the size of the lens. This collection is a source of light that play roles in determining the application of textile telescope. This means that more open and brighter image editing. Size and weight can be used in a special report. Telescope is easy to transport, with a size less than 30 mm. 5x25 or 5x30 models could easily carry the bag. Low magnification is a good size for the photos.

Binoculars 40 mm, a range of sizes. This is considered by most people for some programs. 50-60 mm lens that is difficult to sustain. But also suitable for astronomy.

Months.

Telescope has a large car. Weight glasses can be compared with the maximum load on the legs. Travel with a minimum capacity of 12 kg and 15 kg or more of the best 80 mm binocular.
Prism type.

Form of new versions of the Porro prism binoculars are ideal for astronomy. Porro prism, which is not cheap. This may be an image of good hands.

Light helps you see the body at a time. Because the light or path. This can also display pictures and about 3 times the time light.

File Types.

Astronomy telescope is a CF (Focus) and (each focus lens). Main focus is flexible and easy to use, especially for reorientation. From other programs. When the meditation practice, easier to seal against moisture and dust.

Price and quality.

Most of the giant telescopes in China. Chinese Optics certain pattern of light. Brand-name is.

Celestron.
Oberweck.
Meade.
E Apogee.

Small camera, the quality of $ 25. I of $ 50 - $ 75, while the 80 mm telescope is $ 100 and $ 300 version with 100 mm, with the $ 400 to $ 1000, especially for. luxury resoluble eyes.
