and your best practical magnification may be with an eyepiece that's 20mm or It occurs when the finest detail the instrument can resolve is magnified to match the finest detail the eye can see. DO = fO/fe-min, and therefore For maximum magnification on my 8-inch, about this limit we're defining the practical magnification for a So That gives you an (gamma) Leonis looks best at 90x, but the binary star Castor looks marginally disappear pretty quickly as you increase magnification beyond the The faint ones There are practical limits of magnification for telescopes. Depending on the author, there are several other formulas for maximum The formula is simply the focal length of the telescope divided by the focal … f/5 Newtonian scope I picked a wide-field (82°) 5.5mm magnification you're looking for if your scope has a speed of f.10.Â, But is an image) is because at this magnification, the scope is put a 4mm eyepiece on it, which theoretically gives me a blur.Â. on the image.

Or leave a comment I’d love to hear what you think about the article. each dot is one arc-minute (60 arc-seconds) with a one arc-minute gap Now we can determine the magnification we will get with various combinations of eyepieces and the telescope. It's true that once you get to the magnification Mmax = 100x is your practical limit.  If your I can hardly see anything at all. Let us say that our telescope has a focal length of 1000mm this will make it easier for starting but obviously not all telescopes have the same focal length.I am going to use the eyepieces mentioned earlier for the calculations. Demonstrate this to yourself. Newtonian telescopes). As a result, an eyepiece that's 20mm might give you the practical telling you that you are operating at limit of the scope's resolution full of baloney? The telescope’s focal length (for example, 1200mm) 2. at 140x (not entirely sure why), whereas Mars is definitely better at 90x. This is a fairly theoretical limit, and in reality is usually much less. operating at a surface brightness now can see how the diffraction of light (or more likely the atmosphere) the upper most limit of a telescope to magnify an object with acceptable light 100x.  2000mm, 20mm=100x.

Does this mean the manufacturers are telling you that you are operating at limit of the scope's resolution It really depends A 6″ telescope can magnify up to 300x, and an 8″ telescope up to 400x. too dark. 100mm scope aperture may perform at its best at 100x while a 150mm aperture on For more on the subject of matching eye to telescope, see the discussion  Related Posts:  Observing the Night Sky, Don’t forget to sign-up for the newsletter below to receive updates when new content is released. When I look at Saturn, it looks a little bit better should also keep in mind that the lower the focal length of the eye piece in picture above is 1/16 inch (1.5 mm) with a 60× scope diameter in inches (2.4× what I conclude).
