Rc vs newtonian
WebGalactic mass consistent with luminous mass is obtained by fitting rotation curves (RC = tangential velocities vs. equatorial radius r) using Newtonian force models, or can be unambiguously calculated from RC data using a model based on spin. In contrast, mass exceeding luminous mass is obtained from multi-parameter fits using potentials … WebAlso in Newtonian Physics time is treated as a variable which is independent of space coordinates, whereas in GR time may not be de-attached from space, being time part of …

WebThe largest-focal-length eyepiece you can use with your telescope is easy to calculate: multiply the focal ratio (the focal length of your scope divided by its aperture) by 7. For example, your Newtonian scope is f/5: the largest-focal-length eyepiece you should use is 35 mm. (Note: there is no harm in using a lower-power eyepiece — you will ... WebMay 7, 2024 · A field flattener is not optional except when using small sensors. The radius of field curvature of a Newtonian without correction is much better: equal to its focal length. …
WebFeb 29, 2024 · So an 8" f/6 Newtonian has curved field with a radius of 1200mm, while an 8" f/4 has a field curvature radius of 800mm. Therefore the faster (f/4) telescope has greater field curvature (a more strongly curved field). In more complex optical systems, there is often not a direct relationship between focal length or focal ratio and WebNewtonian is a good instrument, but probably it is harder to handle (collimation and balancing above all). Also the edge HD is a good instrument, but I'm not sure that the …
