Telescope aperture vs Focal Length

Telescope aperture or Focal length?

Leave a comment

Every telescope can be chosen on the basis of two criteria because one of the main characters that will be taken into account is either aperture or focal length. Aperture in a telescope is the objective length diameter when it is referred to a refracting telescope or the primary mirror when it is referred to reflecting telescope. So, if you switch to greater focal length, it is clearly better to observe remote objects in space such as the Moon, planets, etc. or if you require better observation of DSO (deep space objects) such as galaxies getting a device with greater aperture figures is better.

Leave a comment

I met this little friend on one trip; he was attached free to my hotel room. His name is Baigish 50×50 and he is Russian. He was created on the manufactory called KOMZ – an optical-mechanical factory in Kazan, which has been existed since the time of the Soviet Union.
