One of the most essential factor that wants to be considered just before buying any telescope, specifically if you're new to astronomy, is what you are going to use the telescope for. With this in mind, it's not always obvious that the physical properties of a telescope need to be closely related to your requirements. Two of the most important parameters associated with astronomical telescopes are the aperture (the diameter of the key objective lens or mirror) plus the focal length (the distance from the objective lens or mirror to the point where the image is formed). Having a little basic mathematics, you'll be able to very easily calculate the values of these parameters to assist you decide on the best telescope for your requirements.
The telescope aperture is representative of what exactly is usually described as the physical 'size' of the telescope. The larger the aperture, the more light gathering capability the telescope has. By way of example, a recommended aperture for a definitely helpful initial telescope would be at the least 100mm for a refracting telescope, or 150mm for a reflecting telescope. Employing these figures, we can then calculate how faint an object an observer would be in a position to see: The entrance pupil of the human eye can reach roughly 8mm in diameter when fully adapted to the dark. This is equivalent to an region of 50 square millimetres (50mm 2). The refracting telescope having an aperture of 100mm in diameter has an region equivalent to roughly 7850mm two. Stargazing is among the most fascinating hobbies and quality items like the Brunton Lite Tech on this page will make the experience even far more magical.
Which is a good, compact monocular?
I'm looking for a good, compact monocular. Considering the Brunton LITE-TECH® MONOCULAR. Are there better/cheaper ones around?
Amazon.com has quite a few. Depends on your overall criteria, but this might be a good choice.

The 100mm aperture telescope is for that reason capable of collecting 7850/50 = 157x more light, which is then obtainable by way of the telescope eyepiece. In other words, looking by means of the telescope will allow an observer to see objects that are 157 times fainter than could be observed with the unaided eye. Following the exact same calculation, the 150mm aperture reflecting telescope would allow the very same observer to see objects which were 353 times fainter than could possibly be seen using the unaided eye. Clearly then, if you would like to observe faint star fields or galaxies and nebulae, then a larger telescope aperture is undoubtedly better. For those who have a specific object in mind which you would like to see, then knowing how faint it is actually need to permit you to then 'work backwards' with the above calculation, to ascertain if the telescope you've got would be suitable.
The focal length of the telescope is representative of either the physical 'length' of the telescope, or its optical configuration. A brief focal length will give a wide field of view (the location of night sky which will be seen), with the objects in that field of view appearing smaller, whereas a long focal length will give a narrow field of view, but with the objects appearing bigger. The magnification of the telescope is the result of a combination of the focal length of the telescope itself, and focal length of the telescope eyepiece. A telescope of a particular focal length will create an image of a specific size, which is fixed and won't vary. The eyepiece, effectively applied as a microscope, then views that image. A larger image to start with allows the eyepiece to create a higher magnification. So, by altering the eyepiece, the magnification of the telescope may also be changed. Stargazing is one of the most fascinating hobbies and top quality items like the Brunton Lite Tech on this page will make the expertise even a lot more magical.
