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 … Web1. Newtonian. Lovingly referred to as a “Newt,” this is the simplest type of reflector: a parabolic mirror that reflects the light back to a secondary mirror at a 45º angle, which directs it to an eyepiece or camera. These are excellent for beginners, have short focal ratios, and can have large apertures.
