WebNov 23, 2024 · I have a 130pds newtonian reflector with a coma corrector, and am happy with it. It has a short focal length (650mm) and so is wide field. It is a lot cheaper than an apochromatic. There is an extra challenge with balancing a newtonian, as I have to rotate the telescope within the mounting rings. (I find it hard to explain why. 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 ... WebJan 7, 2024 · Short focal length telescopes – especially Newtonian reflectors – exacerbate this problem, but field curvature is present in most telescopes to some extent.

WebCollimation and coma in a Newtonian telescope By far the most common reason for non-round stars in a Newtonian telescope is poor collimation. This produces an optical aberration called coma. Some examples of the appearance of coma in images can be found in the diagram to the right.

RC scopes are mainly for photographic work and is about the best one can do with 2 mirrors. The two mirrors are hyperboloidal and must be matched exactly in shape.

WebFor a hypothetical orbital system (Sun + single planet) the Newtonian model and the General Relativity (GR) model produce different expressions for the gravitational effect of the Sun on the planet. This is well known. The ratio between the Newtonian and GR effects is expressed in different ways by different writers.

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.
