The space observations
In order to observe celestial bodies it is not obligatory to have a telescope or a binocular! You can see many things just with naked eye eventually, only this instrument was at the disposal of ancient stargazers! But if you have really interested in astronomical observations then you wont manage without good binocular! Of course this device is second in point of the degree of magnification and the size of objective versus to a telescope but in some cases the lesser power turns out to be an advantage! The fact of the matter is that many celestial bodies are so large that they dont conform to the field of the view even the least power telescope! That is why it is better to watch them through a good binocular! Moreover many binoculars are much easier and compact than even the smallest and the most qualitative telescopes and they dont require additional appliances for their installation.
