how to calculate the magnification in prime focus?
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 ...

such as earth ground. Ground your oscilloscope by plugging its three-pronged power cord into an outlet grounded to earth ground. Grounding the oscilloscope is necessary for safety. If a high voltage contacts the case of an ungrounded oscilloscope—any part of the case, including knobs that appear...
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 describe the feeling. But it's not an illusion; it's a measurable effect. A good pair of binoculars can help your brain ...
Calculate the dot product of vectors A = 2 1 and B = 3 2 . The three vectors u = u_x i + 3j + 2k, v = -3i + v_y j + 3k, w = -2i + 4j + w_z k, are mutually perpendicular. Use the dot product to determine the components u_x, v_y, and w_z. ...
When the light ray transverses a material medium of different refractive index, it undergoes refraction. The refraction of light is identified as the bending of light and is caused by the change in the speed of light in different material media....
Interesting. I have finders on all my telescope, and use them all at the same rate -- never. With plate-solving and/or with an APPM model, I just tell the mount where to go and it goes there. Yep, no "thrill of the hunt" for me. Just the thrill of the catch. ...
Within sampling, the lowest amount of magnification — or smallest sample size — could make the most sense, given the level of precision needed, as well as timeline and budgetary constraints. If you’re able to detect statistical significance at a difference of 10%, and 10% is a meaningful...
Hazard and risk assessment of nanomaterials (NMs) face challenges due to, among others, the numerous existing nanoforms, discordant data and conflicting results found in the literature, and specific challenges in the application of strategies such as gro
