Aperture.

When the pair first astronomical telescope is open. Size opening in front of the lens of the telescope. The biggest target more light will be collected and the number of astronomical dark themes, more light allows you to see the best. Say what you will be able to open when the number of glasses to match the size of the telescope. So, you see the pair means that you have binoculars 7x50 size is 50 mm. Cell size 25X100 binocular telescope will be more perfect! All 25X100 binoculars because they have legs to be too. Aperture is known as the lens diameter and number will be your own telescope.

Zoom.

Glass to count the first number. Binoculars for astronomy at least 7 times but not more than 10 times, or you must have the legs for easy handling.

The student.

Because the human eye is the size of the student in the evening is that if you have a 7 mm for the binocular telescope will be at least 7 mm exit pupil.

Prisma.

Prisms in the use of binoculars, they oppose the right. There are two types of roof and Porro. CommProve roof prism and display dimmer. They are also very expensive. Porro prism in one another that has a different convenient Prisms, but often heavy and bulkier. Spyglass telescope, and the greater weight should be better.
