If you are looking for an even greater image scale, you can introduce a teleconverter, which effectively doubles the magnification of the lens, depending on the degree of magnification. The only caveat to this imaging technique is that it reduces the amount of light that enters the camera and...
Related to this Question How do you calculate the total magnification of a microscope? How do you determine the magnification of a microscope's eyepiece? A microscope produces an image that is 5.5 x 10-4 m high using a magnification of 125 times. What is the actual size of the object?
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 ...

Depth-of-field calculations are flawed. They calculate the largest aperture that will give barely passable sharpness. They do not calculate the aperture which will give you the sharpest photo, just the bare minimum.Depth-of-field charts and scales came from an era where film was very slow and...
When using a standard light microscope, the objective lens usually provides a certain level of magnification, but so does the ocular lens. The ocular...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question O...
If you know the barlow's focal length then there are formulas that can tell you the magnification and spacing that is needed. Then, it isn't too difficult to determine what change there will be in the focus position. However, most manufacturers don't state the focal length of the barlow...
Depending on the pair you pick, you could see 25 or even 50 times more stars with binoculars than with your unaided eyes. This is not due to the magnification alone, but to the phenomenon of perceptive narrowing driving a flow state. Some people use the term focus, or clarity, to descri...
If you’re focusing at high magnifications (e.g., you’re using amacro lens), then you’ll struggle to lock focus. Any movement will shake off moisture and may even break the webs. So you must take care to shootonlyon the stillest of days. Check your local weather forecast, and ai...
Oh, and one last note. You’ll notice that nowhere in my testing do I say how to calculate “is my copy sharp”. It’s a meaningless calculation unless you have dozens of copies of the same lens like we do and are using some standard measurement of sharpness. I know, for example th...
