Buying telescope eyepieces Your choice of eyepiece will determine the magnification and the size of the field of view that your telescope will deliver. You can pay anything from around £30 up to £400 for a good eyepiece, and an item with the latter sort of price tag is something you...
You can use the changes in the light intensities to calculate the rate of the asteroid's rotation. Comets and Meteors Comet Kohoutek Photo courtesy of NASA A comet or a meteor streaking across the sky is an exciting sight for anyone, and a telescope can make these objects even more ...

Put your scientific calculator in degree mode and calculateAFoV = 2*arctan(L/(2*X))(arctan() may be denoted as the inverse tangent, i.e. tan with a superscript -1). If you mean TRUE field of view, Ed Z. and David Knisely just yesterday wrote about how to do this with drift ...
To calculate the exit pupil divide the objective lens size by magnification. So the higher the magnification, the larger the objective lens needed to maintain image brightness. As a general rule of thumb, try to get a scope where the exit pupil is 1.33mm or more. ...
Every telescope also has afocuser.8This is the short tube that protrudes from the bottom of the tube on a refractor or compound scope, and near the open end of the tube on a reflector. This is also where you’ll insert your eyepiece and lean in to observe your target. ...
It’s a diverging lens that spreads out rays of light for a clearer, more magnified image. How do you calculate the magnification of a telescope? To determine this, you’ll need the focal length (FL) of the eyepiece and focal length of the lens.The magnification is the ...
Compound microscopes are capable of magnifying objects up to 1,000 times. Specimens smaller than can be seen with the naked eye -- objects as small as 100 nanometers -- can be seen in detail with these microscopes. Estimating the size of different specim
Calculate magnification by dividing the focal length of the telescope by the focal length of the eyepiece. For example, a 900mm refractor, when used with a 10mm eyepiece, provides a magnification of 90x. Consult the owner's manual for your Meade telescope to determine its focal length. ...
