Usually the first number is the magnification (in this case 30X) and if it has a zoom from 10X to 30X it would look like 10 - 30X25. The second number is the objective diameter (in mm) of the binocular. The larger the diameter usually means more light is let in and more field of view. 8X42 for example has an 8 times magnification with an objective diameter of 42mm for each side (each monocular).
The DCF is a way of describing a roof shape of the internal prism binocular. It means "Dach Centre Focus" (Dach is German for roof).
The first number specifies the amount of magnification (10 times in this case) and the second number(25) has to do with the amount of light the binocular takes in, measured in mm
10x means 10-times linear magnification, and 25 means a 25-mm object lens at the top of the telescope.

The difference between binoculars and celestron binoculars is that celestron binoculars can see farther and closer. But of course they do cost a lot more.
There is not an antonym for binoculars.
Binoculars in Tagalog is Largabista.
Only thing to help is that "jumelles" means binoculars in French. THere must be millions of jumelles with brass and black trim.

there are 10 millimetres in each centimetre. so 10x25 gives 250mm in 25 cm.
If you mean: -3-10x = 25+4x then the value of x works out as -2
